| 10 | Who even knows? | 谁知道呢? |
| 11 | And you know those body scanners? | 你知道那些身体扫描仪吗? |
| 12 | Can they see you naked? | 他们能看到你裸体吗? |
| 13 | And why does it feel like every airport's got its own rules? | 为什么每个机场都有自己的规则? |
| 14 | I'm Hannah. | 我是汉娜。 |
| 15 | This is What in the World from the BBC World Service. | 这是英国广播公司世界服务社的《世界》。 |
| 16 | And we're going to get into all of this airport tech with our favourite science gal, Caroline Steele. | 我们要和我们最爱的科幻女郎卡罗琳·斯蒂尔 一起进入所有机场技术 |
| 17 | Hey. | 顿 |
| 18 | Hello. | 哈罗 |
| 19 | Thanks for having me on again. | 谢谢你再次邀请我 |
| 20 | So today we're going on a trip, right? | 今天我们要去旅行,对吧? |
| 21 | We're going on a long haul flight on a vacation. | 我们要去度假的长途飞行 |
| 22 | I'm wearing my summer dress and I want you to talk me through every single step of what goes on at airport security. | 我穿着我的暑期礼服 我要你跟我谈谈 机场保安的每一步 |
| 23 | So we're going to start off at check-in. | 我们从报到开始 |
| 24 | We've just sent off our luggage on that belt. | 我们刚刚把行李放在腰带上 |
| 25 | What happens to it next? | 接下来呢? |
| 26 | So your bag goes onto a belt and often goes underground into this huge belt system. | 所以,你的包 进入一个带, 并经常去地下 进入这个巨大的带系统。 |
| 27 | So Denver International Airport in the US, I think, has 35 kilometres of baggage belts. | 所以,我认为,美国丹佛国际机场有35公里的行李带。 |
| 28 | Yeah, I think Dubai has 90 kilometres. | 是的,我认为迪拜有90公里。 |
| 29 | I mean, these systems are huge. | 我的意思是,这些系统是巨大的。 |
| 30 | And as part of this process, your bag will also pass through a scanner, just like your hand luggage does. | 作为这个过程的一部分 你的包也会通过扫描仪 就像你的手提行李一样 |
| 31 | And it's looking for basically anything that could be an explosive. | 它正在寻找任何可能爆炸的东西。 |
| 32 | If your bag does contain something suspicious, it will be opened, which I always forget when I pack my suitcase. | 如果你的包里有可疑的东西 就会打开 我收拾行李的时候就忘了 |
| 33 | I don't think anyone's going to rifle through it. | 我不认为有人会通过它。 |
| 34 | But if there's something suspicious in there, it will be opened, which is why a lot of people, if they want to lock their bags, | 但如果里面有可疑的东西 就会被打开 所以很多人要锁上行李 |
| 35 | will buy sort of an airport approved lock that can be unlocked by people. | 将购买某种机场 批准的锁, 可以被人们解锁。 |
| 36 | So your bag doesn't have to be sort of ripped into. | 所以你的包不必被扯进去 |
| 37 | There are also sometimes sniffer dogs as well, which can, you know, check and have an explosive. | 有时也会有嗅探犬, 它们可以,你知道,检查和有炸药。 |
| 38 | Then your bag continues on this huge, vast system and it ends up on your flight. | 然后,你的包继续 在这个巨大的,巨大的系统, 它结束在你的飞行。 |
| 39 | Once you're on board, a system checks that all bags that have been checked in have a human on the flight that matches them. | 一旦登机,系统检查所有检查过的袋子 飞机上有一个和它们匹配的人 |
| 40 | And if you check in a bag, but you don't end up on the flight, your bag has to be removed. | 如果你检查一个袋子, 但你不会最终在飞行, 你的包必须去除。 |
| 41 | Have you ever been sort of sat ready to take off and then you hear over the speaker system, | 你是否曾坐着准备起飞 然后听到扩音系统的声音 |
| 42 | oh, sorry, we've just got to wait for a bag to be removed from the hold because someone hasn't boarded the plane. | 哦,对不起,我们只是 等待一个袋子 取出搁置 因为有人还没有登机。 |
| 43 | It takes forever, can't it? | 它需要永远,不是吗? |
| 44 | It takes forever and you see these poor people out the window rifling through and trying to find the right bag. | 它需要永远,你看到这些穷人 窗外横跨,试图找到正确的袋子。 |
| 45 | I feel really sorry for them. | 我为他们感到非常抱歉。 |
| 46 | But it's all for a good reason. | 然皆为善根故. |
| 47 | It's to make sure that we don't fly with unattended, sort of unattended bags. | 它是为了确保我们不会用无人看管的袋子来飞行。 |
| 48 | And this happened in 1988 when a bomb went off on a plane over Lockerbie in Scotland | 这发生在1988年 当时苏格兰洛克比上空的飞机上 一枚炸弹爆炸了 |
| 49 | and the owner of the bag wasn't on board the flight. | 包的主人没有在飞机上 |
| 50 | Yeah, so it is for a really good reason, isn't it? | 是啊,所以这是一个很好的理由,不是吗? |
| 51 | It is to keep us safe. | 是为了保护我们的安全 |
| 52 | So we've got through the check-in. | 所以,我们已经通过报到。 |
| 53 | Now we're on to security. | 现在我们去保安处了 |
| 54 | Yeah. | 对 |
| 55 | And we're going to leave our bag in the scanner in a sec. | 我们马上把包放在扫描仪里 |
| 56 | But first of all, we're going to walk through these gates where we have to stand like this, these body scanners. | 但首先,我们要穿过这些大门, 在那里我们必须站着,这些身体扫描仪。 |
| 57 | These ones or this sometimes. | 这些或这个有时。 |
| 58 | Sometimes it's like this, isn't it? | 有时是这样的,不是吗? |
| 59 | How do they work? | 他们怎么工作的? |
| 60 | So they're called millimetre wave scanners and basically they fire radio waves at your body | 因此,它们被称为毫米波扫描仪 基本上,它们发射无线电波 在你的身体 |
| 61 | and they have a wavelength that you can measure in millimetres, which is why they're called millimetre wave scanners. | 他们有一个波长,你可以用毫米测量, 这就是为什么它们被称为毫米波扫描仪。 |
| 62 | But the wavelength is really important because it's basically just the right size that these waves pass through your clothes, | 但是波长很重要 因为这些波从你的衣服里穿过 基本上是合适的大小 |
| 63 | but they reflect off your skin and anything you have hidden underneath your clothes. | 但是它们会从你的皮肤中 以及你藏在衣服底下的任何东西中 反射出来 |
| 64 | And then these reflected waves are picked up by a detector | 然后这些反射波被探测器探测 |
| 65 | and used to build an image of your body and anything that you're hiding underneath your clothes. | 用来塑造你的身体和任何你藏在衣服下面的东西 |
| 66 | But the people working in security, I don't know if you've seen over their shoulder, | 但是那些在保安部门工作的人 我不知道你是否见过他们 |
| 67 | they basically get like a body and then an area will light up that needs further checks. | 基本上,他们得到像一具尸体, 然后一个区域会亮出来, 需要进一步检查。 |
| 68 | And that's when you end up with like an awkward ankle pat down. | 这时你最后会像一个尴尬的脚踝拍下来。 |
| 69 | Yeah. | 对 |
| 70 | A lot of people call them virtual strip searches because of the way that they can take off your clothes. | 很多人称他们为虚拟脱衣搜查,因为他们可以脱下你的衣服. |
| 71 | And there was actually an earlier iteration of these machines when they were first rolled out that could actually see you naked, right? | 这些机器最初被推出时 曾经有过一次重复 可以看到你裸体,对吧? |
| 72 | I mean, the tech itself can build an outline of your body in the sense that that is what it's doing. | 我的意思是,技术本身 可以构建一个轮廓 你的身体,从这个意义上说,它在做什么。 |
| 73 | It's firing particles or waves at your body and picking up on the reflections. | 它向你的身体发射粒子或波浪 并收集反射。 |
| 74 | But that isn't what the staff see. | 但工作人员不这么认为 |
| 75 | The staff just see here's an area of concern, check that out. | 工作人员只是看到这里有一个值得关注的地方, 看看这个。 |
| 76 | But yes, an earlier version of body scanner basically was unsuccessful | 但是,是的,一个早期的 车体扫描器基本上没有成功 |
| 77 | because people didn't want to get in them because they didn't want to be seen naked. | 因为人们不想进去 因为他们不想被看见裸体 |
| 78 | Fair enough. | 不错 |
| 79 | Fair enough, right? | 公平,对不对? |
| 80 | But all kinds of concerns about about privacy, right? | 但对于隐私的各种担忧,对不对? |
| 81 | And essentially someone being able to see underneath your clothes. | 基本上有人能看见你的衣服下面 |
| 82 | Yeah. | 对 |
| 83 | So at the same time as we're going through this body scanner, | 所以,与此同时,我们通过 这个身体扫描仪, |
| 84 | our bag is on the little conveyor belt and it's going through these scanners, which are x-rays, right? | 我们的包在小传送带上,它正在穿过这些扫描仪, 这些是X光,对不对? |
| 85 | So the really modern ones, which actually are in quite a lot of airports now, are CT scanners, | 所以真正现代化的, 实际上是在很多机场 现在,是CT扫描仪, |
| 86 | like the ones you see in a hospital, but they use x-rays. | 就像你在医院里看到的 但他们用X光 |
| 87 | So basically, you put your bag in the scanner. | 所以基本上,你把你的包 在扫描仪。 |
| 88 | It's fired at with x-rays from all different directions and different objects in your bag absorb, | 它用X射线发射 从所有不同方向 和不同的物体 在你的包吸收, |
| 89 | scatter or let different amounts of x-rays basically pass through. | 分散或让不同数量的X射线基本通过. |
| 90 | And those x-rays are picked up by detectors on the other side and used to build a 3D image of what's going on inside your bag. | 这些X光被另一边的探测器取出, 用来构建一个3D图像 显示你包里发生的事情。 |
| 91 | And as a general rule, more dense materials absorb more x-rays than less dense materials. | 而一般来说,密度较大的材料吸收的X射线比密度较低的材料多. |
| 92 | And this 3D image is often also colour coded so that the screeners, | 而这个3D图像也经常被编码成颜色,这样屏幕显示器, |
| 93 | which are the people, you know, sat looking at the inside of your bag, can sort of make sense of them more quickly. | 就是这些人,你知道,坐着看着你包里的东西, 可以更快地理解他们。 |
| 94 | So often orange is given to organic materials. | 因此,橙色常被赋予有机材料. |
| 95 | So that's things like clothes and food. | 这就是衣服和食物 |
| 96 | Green is often given to mixed materials. | 绿色常被赋予混合材料. |
| 97 | So that might be something like electronics. | 所以,这可能是 像电子的东西。 |
| 98 | And blue is often given to metals. | 而蓝色常被赋予金属. |
| 99 | So a gun, for example, could show up as blue. | 所以,比如枪,可以出现为蓝色. |
| 100 | And interestingly, I thought that this would be quite a fun job. | 有趣的是,我认为这是 一个相当有趣的工作。 |
| 101 | Like, I've always thought, you know, I could sit there and snoop on people's bags for hours. | 就像,我一直想,你知道, 我可以坐在那里 和窥探在人们的包上几个小时。 |
| 102 | That just sounds quite fun. | 这听起来很有趣。 |
| 103 | But apparently, it's really easy to switch off. | 但很明显,它真的很容易关闭。 |
| 104 | So research basically shows that we get worse at picking up on things that happen less frequently. | 因此,研究基本上表明,我们更难发现 发生较少的事情。 |
| 105 | So that could be a screener looking for an explosive or a weapon. | 因此,这可能是一个屏幕 寻找炸药或武器。 |
| 106 | That could be a doctor looking for cancer in a scan. | 可能是医生在扫描中寻找癌症 |
| 107 | It's called the low prevalence effect. | 这被称为低流行效应. |
| 108 | And basically, to avoid this, a lot of airports do something called threat image projection, | 基本上,为了避免这种情况, 很多机场都做了一些 所谓的威胁图像投影, |
| 109 | where they basically insert the image of something dangerous into random scans of people's bags to keep the screeners on their toes. | 将危险的东西的图像 插入到人们的袋子的随机扫描中 以保持屏幕上的脚趾 |
| 110 | So their kind of answers are recorded. | 所以他们的答案被记录下来。 |
| 111 | And if they're not picking up on these projected threatening images, then that data gets fed into training. | 如果他们不接收到这些预测的威胁图像, 那这些数据就会被输入训练中。 |
| 112 | They're looking for dangerous objects, these guns, explosive weapons, drugs, anything illegal, also liquids. | 他们正在寻找危险的物体,这些枪支,爆炸性武器,毒品,任何非法的东西,还有液体. |
| 113 | That seems to be one of the most frustrating things, because a lot of the time you've got to get your liquids into these tiny little 100 millilitre bottles, | 这似乎是最令人沮丧的事情之一, 因为很多时候你必须 得到你的液体 进入这些小小100毫升瓶, |
| 114 | and they've got to fit in a little plastic bag. | 他们必须装在一个塑料袋里 |
| 115 | Where did that rule come from? | 这个规则从哪里来的? |
| 116 | And can they actually tell the difference between different types of liquids when they put them in the scanner? | 他们把不同种类的液体放进扫描仪时 能分辨出它们之间的区别吗? |
| 117 | So this all comes from in 2006. | 所以这一切都来自2006年。 |
| 118 | There was basically a foiled liquid explosives plot where people were going to create an explosion on board a plane | 基本上有一个被挫败的液态炸药 在那里人们要制造爆炸 在飞机上 |
| 119 | that was taking off from Heathrow to somewhere in North America using liquids. | 从希思罗飞到北美的某个地方 用液体 |
| 120 | And the issue is, X-rays aren't very good at telling different liquids apart because they have really similar densities. | 问题是,X光片不太擅长分辨不同的液体, 因为它们的密度非常相似。 |
| 121 | So an explosive liquid could look very similar to a bottle of water. | 因此,爆炸性液体可以看起来非常类似于一瓶水. |
| 122 | And there's not much we can do about that. | 我们对此无能为力。 |
| 123 | So to basically avoid liquids as a problem, this rule got introduced where you could only carry on a tiny amount, | 所以,为了避免液体作为一个问题, 这个规则被引入 在那里你只能继续 微小的数量, |
| 124 | so it's less threatening, and you often have to put them in a clear plastic bag so people can see exactly what's going on. | 所以威胁较小,你常常必须把它们放进一个清晰的塑料袋里,这样人们才能看清到底发生了什么。 |
| 125 | But yeah, that's a pain. | 但是,是的,这是一个痛苦。 |
| 126 | And that is the one that always catches me out. | 而那个总是能让我脱身的 |
| 127 | I always have a water bottle hanging around in the bottom. | 我总是有一个水瓶 挂在底部。 |
| 128 | And it's really embarrassing when you have to sort of, you know, go and take it back through. | 这真的很尴尬 当你必须,你知道的,去把它带回去。 |
| 129 | Yeah, you see all of the bottles stacked up. | 是啊,你看所有的瓶子都堆起来了。 |
| 130 | Yes, all the people practically drinking them. | 是的,所有的人几乎都喝他们。 |
| 131 | I'm always downing my water. | 常降水势. |
| 132 | Yeah, I'm so hydrated on every flight. | 是啊,我是如此水分 每一次飞行。 |
| 133 | I'm desperate for a wee. | 我渴望一个小。 |
| 134 | And sometimes you get brought over to do a manual search. | 有时你被带过来做人工搜索。 |
| 135 | And I've seen they get these like little ones with these swabs on the end and they kind of put them through this little, | 我见过他们得到这些 像小的 与这些擦肩而过, |
| 136 | they put them around your bag and all around the zippers and then they put them in this little machine and it beeps. | 他们把它们放在你的包里, 和所有的拉链周围, 然后他们把它们放在这个小机器里, 它鸣叫。 |
| 137 | What are they looking for there? | 他们在找什么? |
| 138 | So they're looking for explosives. | 他们在找炸药 |
| 139 | And I think this bit of tech is just so clever because it can pick up on one billionth of a gram. | 我认为这种技术太聪明了,因为它能用十亿分之一的美元。 |
| 140 | So they are so, so sensitive. | 所以他们是如此,如此敏感。 |
| 141 | Yeah, really, really tiny amounts. | 是啊,真的,真的很小的数量。 |
| 142 | So what happens? | 发生什么了? |
| 143 | Yeah, you get swabbed with a little bit of white cloth normally, then that gets put into a machine. | 是啊,你被涂 一点点白布 通常,然后被放进机器。 |
| 144 | It's called an ion mobility spectrometer. | 称为离子移动光谱仪. |
| 145 | And the machine heats up the swab and basically these tiny, tiny traces of chemicals evaporate and turn into a gas. | 机器加热了瓦片 基本上这些微小的化学物质 蒸发成气体 |
| 146 | That gas is then ionized, which basically means turned into charged particles. | 然后,气体被电离化, 这基本上意味着变成电荷粒子。 |
| 147 | And these charged particles are passed through a tube which has an electric field across it. | 这些带电的微粒通过一个管子, 它有一个电场。 |
| 148 | And different particles move at different speeds through this tube, depending on their size, shape and charge. | 而不同的粒子通过这个管子以不同的速度移动,取决于它们的大小,形状和电荷. |
| 149 | So each particle is basically timed as it moves through the tube. | 因此,每个粒子在通过管子移动时基本上都是定时的. |
| 150 | And then it's compared to a database of known threatening materials or compounds. | 然后与已知威胁材料或化合物的数据库进行比较. |
| 151 | So if a particle moves through, I'm making this up, but 3.72 seconds and that matches an explosive, you'd then be called for further testing or questioning. | 所以,如果一个粒子穿过,我正在编造这个, 但是3.72秒和炸药匹配, 你会被要求做进一步的测试或询问。 |
| 152 | That's incredible because it happens so fast. | 这是不可思议的,因为它发生得太快。 |
| 153 | It literally takes five seconds in front of your eyes and it's going through all those stages. | 它从字面上在你的眼前 花了5秒钟,它正在经历所有这些阶段。 |
| 154 | So one thing that's happened to me in a couple of airports, they've asked me to take my shoes off if I'm wearing my boots or trainers. | 因此,在几个机场里发生的一件事, 他们要求我脱鞋,如果我穿着靴子或教练。 |
| 155 | Some of them also want me to take my watch off. | 他们中有些人还想让我把表拿掉 |
| 156 | Others are like, no, it's absolutely fine. | 其他人喜欢,不, 这是绝对的罚款。 |
| 157 | Just keep your watch on, keep your electronics in your bag. | 只要保持你的表, 把你的电子在你的包。 |
| 158 | Why do they make you take your shoes and watches off at some point, not all? | 为什么他们要你脱鞋看人? |
| 159 | Yes, and I hate this, and belts as well. | 是的,我讨厌这个,还有皮带 |
| 160 | And if you get it wrong, you feel like such a creep taking your belt off or taking your shoes off. | 如果你弄错了,你感觉像一个变态 脱下你的皮带或脱鞋。 |
| 161 | And then it's like, no, put your belt and shoes back on. | 然后它就像,不, 把你的皮带和鞋子回来。 |
| 162 | And you're like, oh, sorry. | 你就像,哦,对不起。 |
| 163 | Getting dressed in front of people. | 于众生前着衣. |
| 164 | Yeah, exactly. | 没错 |
| 165 | It's so awkward. | 真尴尬 |
| 166 | And these differences happen for different reasons. | 而这些差异是因不同的原因发生的. |
| 167 | Not all airports have these millimeter wave scanners. | 并非所有机场都有这些毫米波扫描仪. |
| 168 | Some still use metal detectors. | 有些人仍然使用金属探测器。 |
| 169 | So if you're in an airport that uses metal detectors, then you need to take off anything that has any metal. | 所以,如果你在一个使用金属探测器的机场, 那你需要脱下任何有金属的东西。 |
| 170 | So that might be your belt, your shoes, your watch. | 这可能是你的皮带,你的鞋子,你的表。 |
| 171 | Some airports also want you to remove your shoes because you can conceal things in your shoes, | 有些机场也想让你脱鞋 因为你可以把东西藏在鞋里 |
| 172 | which wouldn't be picked up by a millimeter wave scanner. | 它不会被一个毫米波扫描仪接收。 |
| 173 | So that's when you go like this or like this, but would be picked up by the CT scanner or the X-ray scanner that your bag passes through. | 所以当你像这样走的时候, 你会被CT扫描仪或X光扫描仪接走, 你的包通过。 |
| 174 | So, yeah, it's a combination of different factors, but it's a pain. | 所以,是的,是不同因素的结合,但是一种痛苦. |
| 175 | I wish it was the same everywhere. | 我希望到处都一样 |
| 176 | Yeah, yeah, me too. | 是啊,是啊,我也一样。 |
| 177 | I mean, I understand that these rules have got to change and adapt and stuff, but it's also a technology thing, isn't it? | 我的意思是,我明白,这些规则 必须改变和适应 的东西,但它也是一个技术的事情,不是吗? |
| 178 | Some airports have got more developed, some airports have got less developed technology. | 有的机场较为发达,有的机场技术较不发达. |
| 179 | So it's just one of those things that changes. | 所以它只是其中之一 改变。 |
| 180 | But Caroline, I'm glad to say we passed through airport security. | 但是Caroline 我很高兴我们通过机场保安 |
| 181 | We've made it into the country. | 我们成功了 |
| 182 | We made it to our holiday destination. | 我们到了我们的度假目的地。 |
| 183 | Some airports, though, also make you scan all of your baggage when you arrive. | 不过有些机场也让你在抵达时扫描所有行李. |
| 184 | So what's that about? | 那又怎样? |
| 185 | Yes, it can be a couple of things. | 是的,它可以是 几件事情。 |
| 186 | So when you when you board your plane, that security is checking for anything that might be a threat to a flight. | 所以当你登机时 保安正在检查 任何可能威胁到飞行的东西 |
| 187 | If you're checked further when you enter a country, that's the country caring about what you're bringing into the country. | 如果你在进入一个国家时被进一步检查,那就是关心你带进国家的东西的国家. |
| 188 | Like customs? | 海关? |
| 189 | Yes, it's either customs or biosecurity. | 是的,不是风俗就是生物安保 |
| 190 | So customs are looking for things like they don't want you to be bringing in drugs or weapons. | 海关在寻找他们不希望你带毒品或武器的东西 |
| 191 | So you could be looking for that. | 所以,你可以寻找这一点。 |
| 192 | Biosecurity is looking for anything that could be a threat to the ecosystem that you're arriving into. | 生物安保正在寻找任何可能威胁到你即将到达的生态系统的东西。 |
| 193 | So Australia and New Zealand are really, really hot on this. | 因此澳大利亚和新西兰都非常热衷于这个。 |
| 194 | So they look for things like plants, animals. | 因此,他们寻找的东西 像植物,动物。 |
| 195 | You know, some people smuggle animals onto planes, food, because they don't want any of that to come in, | 有些人把动物偷运到飞机上 吃东西 因为他们不想让这些东西进来 |
| 196 | because you could accidentally introduce an invasive species or a pest or a disease to a fragile ecosystem. | 因为你可以不小心把入侵物种 或害虫或疾病引入脆弱的生态系统 |
| 197 | I've noticed that fewer airports are now asking me to take my liquids out and my electronics. | 我注意到 机场越来越少了 要求我把液体和电器拿出来 |
| 198 | I was just wondering if we have any idea of what airport security might look like in the future. | 我只是想知道我们是否知道 机场安全今后会是什么样子 |
| 199 | Liquids not needing to be taken out is basically because the tech has improved. | 不需要取出的液体基本上是因为技术有了改进。 |
| 200 | These CT scanners are much better at being able to distinguish between liquids. | 这些CT扫描仪更能区分液体. |
| 201 | So that's great when you get somewhere and they're like, leave your liquids in. | 所以,这是伟大的 当你得到某处, 他们喜欢,把你的液体留在。 |
| 202 | Amazing, unless you've already taken your liquids out, in which case annoying. | 惊人,除非你已经 把你的液体拿出来,在这种情况下令人讨厌。 |
| 203 | But I think the future of airport security is going to be so much less fiddly and faffy. | 但我认为机场安全的未来 将少得多 虚无和虚无。 |
| 204 | And if you look at other countries, there are already some amazing examples. | 如果你看看其他国家,已经有一些惊人的例子。 |
| 205 | So in Frankfurt, in Germany, you don't sort of stand like this for your millimetre wave scanner as you pass through security. | 所以在法兰克福,在德国, 在你通过安全系统时,你不会像这样站着。 |
| 206 | You just walk through it and it scans you as you walk, which I think is so cool. | 你只是走过它, 它扫描你 当你走, 我认为如此酷。 |
| 207 | In Dubai, certain passengers can use what they call a red carpet corridor, | 在迪拜,某些乘客可以使用所谓的红地毯走廊, |
| 208 | where basically you walk through a corridor and rather than passport control, | 基本上你走过走廊 而不是护照管制 |
| 209 | this corridor scans your face as you go through and you're just allowed through or not allowed through. | 这走廊扫描你的脸 当你走过, 你只是允许通过或不允许通过。 |
| 210 | And I was having a look on their website and it says that they can process 10 people simultaneously | 我在他们的网站上看到 上面说他们可以同时处理10个人 |
| 211 | and some people can pass through it in as quick as three seconds. | 一些人可以快速地通过它 3秒。 |
| 212 | So, yeah, I think everything hopefully in the future, as tech improves, | 所以,是的,我想一切 希望在未来, 随着技术的改进, |
| 213 | it basically allows the systems to become a bit simpler, involve fewer manual steps, fewer manual searches and hopefully we'll get faster. | 它基本上可以让系统变得简单一点, 包括更少的人工步骤,更少的人工搜索, 希望我们能更快。 |
| 214 | Yeah, less stress and more time for a holiday because we made it. | 是啊,减少压力和更多的时间 一个假期,因为我们做到了。 |
| 215 | We've made it to our destination. | 我们已经到达目的地了 |
| 216 | Amazing. | 厉害 |
| 217 | All we've got to do is get to the hotel. | 我们只要到酒店就行了 |
| 218 | Great. | 不错 |
| 219 | 我们池边见 Caroline | |
| 220 | Thanks so much. | 非常感谢 |
| 221 | See you there. | 再见 |
| 222 | Well, I hope that answered some of your questions. | 好吧,我希望这回答了你的一些问题。 |
| 223 | It definitely got to the point of some of mine and if you've got any more, you can drop us a line. | 它肯定有我的一些重点 如果你还有的话,你可以给我们留下一条线。 |
| 224 | I also want to thank you guys for your comments on the episode I mentioned about flying, | 我也要感谢你们对我提到的关于飞行的一集的评论, |
| 225 | about how the body's affected by being up in the air and Shadi said, | 关于尸体是如何受到影响的 在空中和Shadi说, |
| 226 | I can't even begin to explain the pain I feel in my feet when I get off a cross-continental flight. | 我甚至无法解释我从越洲航班上下来时 脚上的疼痛 |
| 227 | It's like walking on pins and needles on hot stones. | 犹如披针而走于热石. |
| 228 | Yeah, I feel you. | 是的,我感觉到你。 |

| 14 | I'm Hannah. | 我是汉娜。 |
| 15 | This is What in the World from the BBC World Service. | 这是英国广播公司世界服务社的《世界》。 |
| 16 | And we're going to get into all of this airport tech with our favourite science gal, Caroline Steele. | 我们要和我们最爱的科幻女郎卡罗琳·斯蒂尔 一起进入所有机场技术 |
| 17 | Hey. | 顿 |
| 18 | Hello. | 哈罗 |
| 19 | Thanks for having me on again. | 谢谢你再次邀请我 |
| 20 | So today we're going on a trip, right? | 今天我们要去旅行,对吧? |
| 21 | We're going on a long haul flight on a vacation. | 我们要去度假的长途飞行 |
| 22 | I'm wearing my summer dress and I want you to talk me through every single step of what goes on at airport security. | 我穿着我的暑期礼服 我要你跟我谈谈 机场保安的每一步 |
| 23 | So we're going to start off at check-in. | 我们从报到开始 |
| 24 | We've just sent off our luggage on that belt. | 我们刚刚把行李放在腰带上 |
| 25 | What happens to it next? | 接下来呢? |
| 26 | So your bag goes onto a belt and often goes underground into this huge belt system. | 所以,你的包 进入一个带, 并经常去地下 进入这个巨大的带系统。 |
| 27 | So Denver International Airport in the US, I think, has 35 kilometres of baggage belts. | 所以,我认为,美国丹佛国际机场有35公里的行李带。 |
| 28 | Yeah, I think Dubai has 90 kilometres. | 是的,我认为迪拜有90公里。 |
| 29 | I mean, these systems are huge. | 我的意思是,这些系统是巨大的。 |
| 30 | And as part of this process, your bag will also pass through a scanner, just like your hand luggage does. | 作为这个过程的一部分 你的包也会通过扫描仪 就像你的手提行李一样 |
| 31 | And it's looking for basically anything that could be an explosive. | 它正在寻找任何可能爆炸的东西。 |
| 32 | If your bag does contain something suspicious, it will be opened, which I always forget when I pack my suitcase. | 如果你的包里有可疑的东西 就会打开 我收拾行李的时候就忘了 |
| 33 | I don't think anyone's going to rifle through it. | 我不认为有人会通过它。 |
| 34 | But if there's something suspicious in there, it will be opened, which is why a lot of people, if they want to lock their bags, | 但如果里面有可疑的东西 就会被打开 所以很多人要锁上行李 |
| 35 | will buy sort of an airport approved lock that can be unlocked by people. | 将购买某种机场 批准的锁, 可以被人们解锁。 |
| 36 | So your bag doesn't have to be sort of ripped into. | 所以你的包不必被扯进去 |
| 37 | There are also sometimes sniffer dogs as well, which can, you know, check and have an explosive. | 有时也会有嗅探犬, 它们可以,你知道,检查和有炸药。 |
| 38 | Then your bag continues on this huge, vast system and it ends up on your flight. | 然后,你的包继续 在这个巨大的,巨大的系统, 它结束在你的飞行。 |
| 39 | Once you're on board, a system checks that all bags that have been checked in have a human on the flight that matches them. | 一旦登机,系统检查所有检查过的袋子 飞机上有一个和它们匹配的人 |
| 40 | And if you check in a bag, but you don't end up on the flight, your bag has to be removed. | 如果你检查一个袋子, 但你不会最终在飞行, 你的包必须去除。 |
| 41 | Have you ever been sort of sat ready to take off and then you hear over the speaker system, | 你是否曾坐着准备起飞 然后听到扩音系统的声音 |
| 42 | oh, sorry, we've just got to wait for a bag to be removed from the hold because someone hasn't boarded the plane. | 哦,对不起,我们只是 等待一个袋子 取出搁置 因为有人还没有登机。 |
| 43 | It takes forever, can't it? | 它需要永远,不是吗? |
| 44 | It takes forever and you see these poor people out the window rifling through and trying to find the right bag. | 它需要永远,你看到这些穷人 窗外横跨,试图找到正确的袋子。 |
| 45 | I feel really sorry for them. | 我为他们感到非常抱歉。 |
| 46 | But it's all for a good reason. | 然皆为善根故. |
| 47 | It's to make sure that we don't fly with unattended, sort of unattended bags. | 它是为了确保我们不会用无人看管的袋子来飞行。 |
| 48 | And this happened in 1988 when a bomb went off on a plane over Lockerbie in Scotland | 这发生在1988年 当时苏格兰洛克比上空的飞机上 一枚炸弹爆炸了 |
| 49 | and the owner of the bag wasn't on board the flight. | 包的主人没有在飞机上 |
| 50 | Yeah, so it is for a really good reason, isn't it? | 是啊,所以这是一个很好的理由,不是吗? |
| 51 | It is to keep us safe. | 是为了保护我们的安全 |
| 52 | So we've got through the check-in. | 所以,我们已经通过报到。 |
| 53 | Now we're on to security. | 现在我们去保安处了 |
| 54 | Yeah. | 对 |
| 55 | And we're going to leave our bag in the scanner in a sec. | 我们马上把包放在扫描仪里 |
| 56 | But first of all, we're going to walk through these gates where we have to stand like this, these body scanners. | 但首先,我们要穿过这些大门, 在那里我们必须站着,这些身体扫描仪。 |
| 57 | These ones or this sometimes. | 这些或这个有时。 |
| 58 | Sometimes it's like this, isn't it? | 有时是这样的,不是吗? |
| 59 | How do they work? | 他们怎么工作的? |
| 60 | So they're called millimetre wave scanners and basically they fire radio waves at your body | 因此,它们被称为毫米波扫描仪 基本上,它们发射无线电波 在你的身体 |
| 61 | and they have a wavelength that you can measure in millimetres, which is why they're called millimetre wave scanners. | 他们有一个波长,你可以用毫米测量, 这就是为什么它们被称为毫米波扫描仪。 |
| 62 | But the wavelength is really important because it's basically just the right size that these waves pass through your clothes, | 但是波长很重要 因为这些波从你的衣服里穿过 基本上是合适的大小 |
| 63 | but they reflect off your skin and anything you have hidden underneath your clothes. | 但是它们会从你的皮肤中 以及你藏在衣服底下的任何东西中 反射出来 |
| 64 | And then these reflected waves are picked up by a detector | 然后这些反射波被探测器探测 |
| 65 | and used to build an image of your body and anything that you're hiding underneath your clothes. | 用来塑造你的身体和任何你藏在衣服下面的东西 |
| 66 | But the people working in security, I don't know if you've seen over their shoulder, | 但是那些在保安部门工作的人 我不知道你是否见过他们 |
| 67 | they basically get like a body and then an area will light up that needs further checks. | 基本上,他们得到像一具尸体, 然后一个区域会亮出来, 需要进一步检查。 |
| 68 | And that's when you end up with like an awkward ankle pat down. | 这时你最后会像一个尴尬的脚踝拍下来。 |
| 69 | Yeah. | 对 |
| 70 | A lot of people call them virtual strip searches because of the way that they can take off your clothes. | 很多人称他们为虚拟脱衣搜查,因为他们可以脱下你的衣服. |
| 71 | And there was actually an earlier iteration of these machines when they were first rolled out that could actually see you naked, right? | 这些机器最初被推出时 曾经有过一次重复 可以看到你裸体,对吧? |
| 72 | I mean, the tech itself can build an outline of your body in the sense that that is what it's doing. | 我的意思是,技术本身 可以构建一个轮廓 你的身体,从这个意义上说,它在做什么。 |
| 73 | It's firing particles or waves at your body and picking up on the reflections. | 它向你的身体发射粒子或波浪 并收集反射。 |
| 74 | But that isn't what the staff see. | 但工作人员不这么认为 |
| 75 | The staff just see here's an area of concern, check that out. | 工作人员只是看到这里有一个值得关注的地方, 看看这个。 |
| 76 | But yes, an earlier version of body scanner basically was unsuccessful | 但是,是的,一个早期的 车体扫描器基本上没有成功 |
| 77 | because people didn't want to get in them because they didn't want to be seen naked. | 因为人们不想进去 因为他们不想被看见裸体 |
| 78 | Fair enough. | 不错 |
| 79 | Fair enough, right? | 公平,对不对? |
| 80 | But all kinds of concerns about about privacy, right? | 但对于隐私的各种担忧,对不对? |
| 81 | And essentially someone being able to see underneath your clothes. | 基本上有人能看见你的衣服下面 |
| 82 | Yeah. | 对 |
| 83 | So at the same time as we're going through this body scanner, | 所以,与此同时,我们通过 这个身体扫描仪, |
| 84 | our bag is on the little conveyor belt and it's going through these scanners, which are x-rays, right? | 我们的包在小传送带上,它正在穿过这些扫描仪, 这些是X光,对不对? |
| 85 | So the really modern ones, which actually are in quite a lot of airports now, are CT scanners, | 所以真正现代化的, 实际上是在很多机场 现在,是CT扫描仪, |
| 86 | like the ones you see in a hospital, but they use x-rays. | 就像你在医院里看到的 但他们用X光 |
| 87 | So basically, you put your bag in the scanner. | 所以基本上,你把你的包 在扫描仪。 |
| 88 | It's fired at with x-rays from all different directions and different objects in your bag absorb, | 它用X射线发射 从所有不同方向 和不同的物体 在你的包吸收, |
| 89 | scatter or let different amounts of x-rays basically pass through. | 分散或让不同数量的X射线基本通过. |
| 90 | And those x-rays are picked up by detectors on the other side and used to build a 3D image of what's going on inside your bag. | 这些X光被另一边的探测器取出, 用来构建一个3D图像 显示你包里发生的事情。 |
| 91 | And as a general rule, more dense materials absorb more x-rays than less dense materials. | 而一般来说,密度较大的材料吸收的X射线比密度较低的材料多. |
| 92 | And this 3D image is often also colour coded so that the screeners, | 而这个3D图像也经常被编码成颜色,这样屏幕显示器, |
| 93 | which are the people, you know, sat looking at the inside of your bag, can sort of make sense of them more quickly. | 就是这些人,你知道,坐着看着你包里的东西, 可以更快地理解他们。 |
| 94 | So often orange is given to organic materials. | 因此,橙色常被赋予有机材料. |
| 95 | So that's things like clothes and food. | 这就是衣服和食物 |
| 96 | Green is often given to mixed materials. | 绿色常被赋予混合材料. |
| 97 | So that might be something like electronics. | 所以,这可能是 像电子的东西。 |
| 98 | And blue is often given to metals. | 而蓝色常被赋予金属. |
| 99 | So a gun, for example, could show up as blue. | 所以,比如枪,可以出现为蓝色. |
| 100 | And interestingly, I thought that this would be quite a fun job. | 有趣的是,我认为这是 一个相当有趣的工作。 |
| 101 | Like, I've always thought, you know, I could sit there and snoop on people's bags for hours. | 就像,我一直想,你知道, 我可以坐在那里 和窥探在人们的包上几个小时。 |
| 102 | That just sounds quite fun. | 这听起来很有趣。 |
| 103 | But apparently, it's really easy to switch off. | 但很明显,它真的很容易关闭。 |
| 104 | So research basically shows that we get worse at picking up on things that happen less frequently. | 因此,研究基本上表明,我们更难发现 发生较少的事情。 |
| 105 | So that could be a screener looking for an explosive or a weapon. | 因此,这可能是一个屏幕 寻找炸药或武器。 |
| 106 | That could be a doctor looking for cancer in a scan. | 可能是医生在扫描中寻找癌症 |
| 107 | It's called the low prevalence effect. | 这被称为低流行效应. |
| 108 | And basically, to avoid this, a lot of airports do something called threat image projection, | 基本上,为了避免这种情况, 很多机场都做了一些 所谓的威胁图像投影, |
| 109 | where they basically insert the image of something dangerous into random scans of people's bags to keep the screeners on their toes. | 将危险的东西的图像 插入到人们的袋子的随机扫描中 以保持屏幕上的脚趾 |
| 110 | So their kind of answers are recorded. | 所以他们的答案被记录下来。 |
| 111 | And if they're not picking up on these projected threatening images, then that data gets fed into training. | 如果他们不接收到这些预测的威胁图像, 那这些数据就会被输入训练中。 |
| 112 | They're looking for dangerous objects, these guns, explosive weapons, drugs, anything illegal, also liquids. | 他们正在寻找危险的物体,这些枪支,爆炸性武器,毒品,任何非法的东西,还有液体. |
| 113 | That seems to be one of the most frustrating things, because a lot of the time you've got to get your liquids into these tiny little 100 millilitre bottles, | 这似乎是最令人沮丧的事情之一, 因为很多时候你必须 得到你的液体 进入这些小小100毫升瓶, |
| 114 | and they've got to fit in a little plastic bag. | 他们必须装在一个塑料袋里 |
| 115 | Where did that rule come from? | 这个规则从哪里来的? |
| 116 | And can they actually tell the difference between different types of liquids when they put them in the scanner? | 他们把不同种类的液体放进扫描仪时 能分辨出它们之间的区别吗? |
| 117 | So this all comes from in 2006. | 所以这一切都来自2006年。 |
| 118 | There was basically a foiled liquid explosives plot where people were going to create an explosion on board a plane | 基本上有一个被挫败的液态炸药 在那里人们要制造爆炸 在飞机上 |
| 119 | that was taking off from Heathrow to somewhere in North America using liquids. | 从希思罗飞到北美的某个地方 用液体 |
| 120 | And the issue is, X-rays aren't very good at telling different liquids apart because they have really similar densities. | 问题是,X光片不太擅长分辨不同的液体, 因为它们的密度非常相似。 |
| 121 | So an explosive liquid could look very similar to a bottle of water. | 因此,爆炸性液体可以看起来非常类似于一瓶水. |
| 122 | And there's not much we can do about that. | 我们对此无能为力。 |
| 123 | So to basically avoid liquids as a problem, this rule got introduced where you could only carry on a tiny amount, | 所以,为了避免液体作为一个问题, 这个规则被引入 在那里你只能继续 微小的数量, |
| 124 | so it's less threatening, and you often have to put them in a clear plastic bag so people can see exactly what's going on. | 所以威胁较小,你常常必须把它们放进一个清晰的塑料袋里,这样人们才能看清到底发生了什么。 |
| 125 | But yeah, that's a pain. | 但是,是的,这是一个痛苦。 |
| 126 | And that is the one that always catches me out. | 而那个总是能让我脱身的 |
| 127 | I always have a water bottle hanging around in the bottom. | 我总是有一个水瓶 挂在底部。 |
| 128 | And it's really embarrassing when you have to sort of, you know, go and take it back through. | 这真的很尴尬 当你必须,你知道的,去把它带回去。 |
| 129 | Yeah, you see all of the bottles stacked up. | 是啊,你看所有的瓶子都堆起来了。 |
| 130 | Yes, all the people practically drinking them. | 是的,所有的人几乎都喝他们。 |
| 131 | I'm always downing my water. | 常降水势. |
| 132 | Yeah, I'm so hydrated on every flight. | 是啊,我是如此水分 每一次飞行。 |
| 133 | I'm desperate for a wee. | 我渴望一个小。 |
| 134 | And sometimes you get brought over to do a manual search. | 有时你被带过来做人工搜索。 |
| 135 | And I've seen they get these like little ones with these swabs on the end and they kind of put them through this little, | 我见过他们得到这些 像小的 与这些擦肩而过, |
| 136 | they put them around your bag and all around the zippers and then they put them in this little machine and it beeps. | 他们把它们放在你的包里, 和所有的拉链周围, 然后他们把它们放在这个小机器里, 它鸣叫。 |
| 137 | What are they looking for there? | 他们在找什么? |
| 138 | So they're looking for explosives. | 他们在找炸药 |
| 139 | And I think this bit of tech is just so clever because it can pick up on one billionth of a gram. | 我认为这种技术太聪明了,因为它能用十亿分之一的美元。 |
| 140 | So they are so, so sensitive. | 所以他们是如此,如此敏感。 |
| 141 | Yeah, really, really tiny amounts. | 是啊,真的,真的很小的数量。 |
| 142 | So what happens? | 发生什么了? |
| 143 | Yeah, you get swabbed with a little bit of white cloth normally, then that gets put into a machine. | 是啊,你被涂 一点点白布 通常,然后被放进机器。 |
| 144 | It's called an ion mobility spectrometer. | 称为离子移动光谱仪. |
| 145 | And the machine heats up the swab and basically these tiny, tiny traces of chemicals evaporate and turn into a gas. | 机器加热了瓦片 基本上这些微小的化学物质 蒸发成气体 |
| 146 | That gas is then ionized, which basically means turned into charged particles. | 然后,气体被电离化, 这基本上意味着变成电荷粒子。 |
| 147 | And these charged particles are passed through a tube which has an electric field across it. | 这些带电的微粒通过一个管子, 它有一个电场。 |
| 148 | And different particles move at different speeds through this tube, depending on their size, shape and charge. | 而不同的粒子通过这个管子以不同的速度移动,取决于它们的大小,形状和电荷. |
| 149 | So each particle is basically timed as it moves through the tube. | 因此,每个粒子在通过管子移动时基本上都是定时的. |
| 150 | And then it's compared to a database of known threatening materials or compounds. | 然后与已知威胁材料或化合物的数据库进行比较. |
| 151 | So if a particle moves through, I'm making this up, but 3.72 seconds and that matches an explosive, you'd then be called for further testing or questioning. | 所以,如果一个粒子穿过,我正在编造这个, 但是3.72秒和炸药匹配, 你会被要求做进一步的测试或询问。 |
| 152 | That's incredible because it happens so fast. | 这是不可思议的,因为它发生得太快。 |
| 153 | It literally takes five seconds in front of your eyes and it's going through all those stages. | 它从字面上在你的眼前 花了5秒钟,它正在经历所有这些阶段。 |
| 154 | So one thing that's happened to me in a couple of airports, they've asked me to take my shoes off if I'm wearing my boots or trainers. | 因此,在几个机场里发生的一件事, 他们要求我脱鞋,如果我穿着靴子或教练。 |
| 155 | Some of them also want me to take my watch off. | 他们中有些人还想让我把表拿掉 |
| 156 | Others are like, no, it's absolutely fine. | 其他人喜欢,不, 这是绝对的罚款。 |
| 157 | Just keep your watch on, keep your electronics in your bag. | 只要保持你的表, 把你的电子在你的包。 |
| 158 | Why do they make you take your shoes and watches off at some point, not all? | 为什么他们要你脱鞋看人? |
| 159 | Yes, and I hate this, and belts as well. | 是的,我讨厌这个,还有皮带 |
| 160 | And if you get it wrong, you feel like such a creep taking your belt off or taking your shoes off. | 如果你弄错了,你感觉像一个变态 脱下你的皮带或脱鞋。 |
| 161 | And then it's like, no, put your belt and shoes back on. | 然后它就像,不, 把你的皮带和鞋子回来。 |
| 162 | And you're like, oh, sorry. | 你就像,哦,对不起。 |
| 163 | Getting dressed in front of people. | 于众生前着衣. |
| 164 | Yeah, exactly. | 没错 |
| 165 | It's so awkward. | 真尴尬 |
| 166 | And these differences happen for different reasons. | 而这些差异是因不同的原因发生的. |
| 167 | Not all airports have these millimeter wave scanners. | 并非所有机场都有这些毫米波扫描仪. |
| 168 | Some still use metal detectors. | 有些人仍然使用金属探测器。 |
| 169 | So if you're in an airport that uses metal detectors, then you need to take off anything that has any metal. | 所以,如果你在一个使用金属探测器的机场, 那你需要脱下任何有金属的东西。 |
| 170 | So that might be your belt, your shoes, your watch. | 这可能是你的皮带,你的鞋子,你的表。 |
| 171 | Some airports also want you to remove your shoes because you can conceal things in your shoes, | 有些机场也想让你脱鞋 因为你可以把东西藏在鞋里 |
| 172 | which wouldn't be picked up by a millimeter wave scanner. | 它不会被一个毫米波扫描仪接收。 |
| 173 | So that's when you go like this or like this, but would be picked up by the CT scanner or the X-ray scanner that your bag passes through. | 所以当你像这样走的时候, 你会被CT扫描仪或X光扫描仪接走, 你的包通过。 |
| 174 | So, yeah, it's a combination of different factors, but it's a pain. | 所以,是的,是不同因素的结合,但是一种痛苦. |
| 175 | I wish it was the same everywhere. | 我希望到处都一样 |
| 176 | Yeah, yeah, me too. | 是啊,是啊,我也一样。 |
| 177 | I mean, I understand that these rules have got to change and adapt and stuff, but it's also a technology thing, isn't it? | 我的意思是,我明白,这些规则 必须改变和适应 的东西,但它也是一个技术的事情,不是吗? |
| 178 | Some airports have got more developed, some airports have got less developed technology. | 有的机场较为发达,有的机场技术较不发达. |
| 179 | So it's just one of those things that changes. | 所以它只是其中之一 改变。 |
| 180 | But Caroline, I'm glad to say we passed through airport security. | 但是Caroline 我很高兴我们通过机场保安 |
| 181 | We've made it into the country. | 我们成功了 |
| 182 | We made it to our holiday destination. | 我们到了我们的度假目的地。 |
| 183 | Some airports, though, also make you scan all of your baggage when you arrive. | 不过有些机场也让你在抵达时扫描所有行李. |
| 184 | So what's that about? | 那又怎样? |
| 185 | Yes, it can be a couple of things. | 是的,它可以是 几件事情。 |
| 186 | So when you when you board your plane, that security is checking for anything that might be a threat to a flight. | 所以当你登机时 保安正在检查 任何可能威胁到飞行的东西 |
| 187 | If you're checked further when you enter a country, that's the country caring about what you're bringing into the country. | 如果你在进入一个国家时被进一步检查,那就是关心你带进国家的东西的国家. |
| 188 | Like customs? | 海关? |
| 189 | Yes, it's either customs or biosecurity. | 是的,不是风俗就是生物安保 |
| 190 | So customs are looking for things like they don't want you to be bringing in drugs or weapons. | 海关在寻找他们不希望你带毒品或武器的东西 |
| 191 | So you could be looking for that. | 所以,你可以寻找这一点。 |
| 192 | Biosecurity is looking for anything that could be a threat to the ecosystem that you're arriving into. | 生物安保正在寻找任何可能威胁到你即将到达的生态系统的东西。 |
| 193 | So Australia and New Zealand are really, really hot on this. | 因此澳大利亚和新西兰都非常热衷于这个。 |
| 194 | So they look for things like plants, animals. | 因此,他们寻找的东西 像植物,动物。 |
| 195 | You know, some people smuggle animals onto planes, food, because they don't want any of that to come in, | 有些人把动物偷运到飞机上 吃东西 因为他们不想让这些东西进来 |
| 196 | because you could accidentally introduce an invasive species or a pest or a disease to a fragile ecosystem. | 因为你可以不小心把入侵物种 或害虫或疾病引入脆弱的生态系统 |
| 197 | I've noticed that fewer airports are now asking me to take my liquids out and my electronics. | 我注意到 机场越来越少了 要求我把液体和电器拿出来 |
| 198 | I was just wondering if we have any idea of what airport security might look like in the future. | 我只是想知道我们是否知道 机场安全今后会是什么样子 |
| 199 | Liquids not needing to be taken out is basically because the tech has improved. | 不需要取出的液体基本上是因为技术有了改进。 |
| 200 | These CT scanners are much better at being able to distinguish between liquids. | 这些CT扫描仪更能区分液体. |
| 201 | So that's great when you get somewhere and they're like, leave your liquids in. | 所以,这是伟大的 当你得到某处, 他们喜欢,把你的液体留在。 |
| 202 | Amazing, unless you've already taken your liquids out, in which case annoying. | 惊人,除非你已经 把你的液体拿出来,在这种情况下令人讨厌。 |
| 203 | But I think the future of airport security is going to be so much less fiddly and faffy. | 但我认为机场安全的未来 将少得多 虚无和虚无。 |
| 204 | And if you look at other countries, there are already some amazing examples. | 如果你看看其他国家,已经有一些惊人的例子。 |
| 205 | So in Frankfurt, in Germany, you don't sort of stand like this for your millimetre wave scanner as you pass through security. | 所以在法兰克福,在德国, 在你通过安全系统时,你不会像这样站着。 |
| 206 | You just walk through it and it scans you as you walk, which I think is so cool. | 你只是走过它, 它扫描你 当你走, 我认为如此酷。 |
| 207 | In Dubai, certain passengers can use what they call a red carpet corridor, | 在迪拜,某些乘客可以使用所谓的红地毯走廊, |
| 208 | where basically you walk through a corridor and rather than passport control, | 基本上你走过走廊 而不是护照管制 |
| 209 | this corridor scans your face as you go through and you're just allowed through or not allowed through. | 这走廊扫描你的脸 当你走过, 你只是允许通过或不允许通过。 |
| 210 | And I was having a look on their website and it says that they can process 10 people simultaneously | 我在他们的网站上看到 上面说他们可以同时处理10个人 |
| 211 | and some people can pass through it in as quick as three seconds. | 一些人可以快速地通过它 3秒。 |
| 212 | So, yeah, I think everything hopefully in the future, as tech improves, | 所以,是的,我想一切 希望在未来, 随着技术的改进, |
| 213 | it basically allows the systems to become a bit simpler, involve fewer manual steps, fewer manual searches and hopefully we'll get faster. | 它基本上可以让系统变得简单一点, 包括更少的人工步骤,更少的人工搜索, 希望我们能更快。 |
| 214 | Yeah, less stress and more time for a holiday because we made it. | 是啊,减少压力和更多的时间 一个假期,因为我们做到了。 |
| 215 | We've made it to our destination. | 我们已经到达目的地了 |
| 216 | Amazing. | 厉害 |
| 217 | All we've got to do is get to the hotel. | 我们只要到酒店就行了 |
| 218 | Great. | 不错 |
| 219 | 我们池边见 Caroline | |
| 220 | Thanks so much. | 非常感谢 |
| 221 | See you there. | 再见 |
| 222 | Well, I hope that answered some of your questions. | 好吧,我希望这回答了你的一些问题。 |
| 223 | It definitely got to the point of some of mine and if you've got any more, you can drop us a line. | 它肯定有我的一些重点 如果你还有的话,你可以给我们留下一条线。 |
| 224 | I also want to thank you guys for your comments on the episode I mentioned about flying, | 我也要感谢你们对我提到的关于飞行的一集的评论, |
| 225 | about how the body's affected by being up in the air and Shadi said, | 关于尸体是如何受到影响的 在空中和Shadi说, |
| 226 | I can't even begin to explain the pain I feel in my feet when I get off a cross-continental flight. | 我甚至无法解释我从越洲航班上下来时 脚上的疼痛 |
| 227 | It's like walking on pins and needles on hot stones. | 犹如披针而走于热石. |
| 228 | Yeah, I feel you. | 是的,我感觉到你。 |

| 15 | This is What in the World from the BBC World Service. | 这是英国广播公司世界服务社的《世界》。 |
| 16 | And we're going to get into all of this airport tech with our favourite science gal, Caroline Steele. | 我们要和我们最爱的科幻女郎卡罗琳·斯蒂尔 一起进入所有机场技术 |
| 17 | Hey. | 顿 |
| 18 | Hello. | 哈罗 |
| 19 | Thanks for having me on again. | 谢谢你再次邀请我 |
| 20 | So today we're going on a trip, right? | 今天我们要去旅行,对吧? |
| 21 | We're going on a long haul flight, on a vacation. | 我们要去长途飞行 度假 |
| 22 | I'm wearing my summer dress. | 我着夏衣. |
| 23 | And I want you to talk me through every single step of what goes on at airport security. | 我要你跟我谈谈机场保安的每一步 |
| 24 | So we're going to start off at check-in. | 我们从报到开始 |
| 25 | We've just sent off our luggage on that belt. | 我们刚刚把行李放在腰带上 |
| 26 | What happens to it next? | 接下来呢? |
| 27 | So your bag goes onto a belt and often goes underground into this huge belt system. | 所以,你的包 进入一个带, 并经常去地下 进入这个巨大的带系统。 |
| 28 | So Denver International Airport in the US, I think, has 35 kilometres of baggage belts. | 所以,我认为,美国丹佛国际机场有35公里的行李带。 |
| 29 | Yeah, I think Dubai has 90 kilometres. | 是的,我认为迪拜有90公里。 |
| 30 | I mean, these systems are huge. | 我的意思是,这些系统是巨大的。 |
| 31 | And as part of this process, your bag will also pass through a scanner, just like your hand luggage does. | 作为这个过程的一部分 你的包也会通过扫描仪 就像你的手提行李一样 |
| 32 | And it's looking for basically anything that could be an explosive. | 它正在寻找任何可能爆炸的东西。 |
| 33 | If your bag does contain something suspicious, it will be opened, which I always forget when I pack my suitcase. | 如果你的包里有可疑的东西 就会打开 我收拾行李的时候就忘了 |
| 34 | I don't think anyone's going to rifle through it. | 我不认为有人会通过它。 |
| 35 | But if there's something suspicious in there, it will be opened, which is why a lot of people, | 但是如果里面有可疑的东西, 它会打开, 这就是为什么很多人, |
| 36 | if they want to lock their bags, will buy sort of an airport approved lock that can be unlocked by people. | 如果他们想锁好行李 就会买一个机场认可的锁 由人们解锁 |
| 37 | So your bag doesn't have to be sort of ripped into. | 所以你的包不必被扯进去 |
| 38 | There are also sometimes sniffer dogs as well, which can, you know, check and have an explosive. | 有时也会有嗅探犬, 它们可以,你知道,检查和有炸药。 |
| 39 | Then your bag continues on this huge, vast system and it ends up on your flight. | 然后,你的包继续 在这个巨大的,巨大的系统, 它结束在你的飞行。 |
| 40 | Once you're on board, a system checks that all bags that have been checked in have a human on the flight that matches them. | 一旦登机,系统检查所有检查过的袋子 飞机上有一个和它们匹配的人 |
| 41 | And if you check in a bag, but you don't end up on the flight, your bag has to be removed. | 如果你检查一个袋子, 但你不会最终在飞行, 你的包必须去除。 |
| 42 | Have you ever been sort of sat ready to take off and then you hear over the speaker system, | 你是否曾坐着准备起飞 然后听到扩音系统的声音 |
| 43 | oh, sorry, we've just got to wait for a bag to be removed from the hold because someone hasn't boarded the plane. | 哦,对不起,我们只是 等待一个袋子 取出搁置 因为有人还没有登机。 |
| 44 | It takes forever, can't it? | 它需要永远,不是吗? |
| 45 | It takes forever. | 它需要永远。 |
| 46 | And you see these poor people out the window rifling through and trying to find the right bag. | 你看到这些穷人在窗外横跨,试图找到合适的袋子。 |
| 47 | I feel really sorry for them. | 我为他们感到非常抱歉。 |
| 48 | But it's all for a good reason. | 然皆为善根故. |
| 49 | It's to make sure that we don't fly with unattended sort of unattended bags. | 它是为了确保我们不会用无人看管的袋子来飞行. |
| 50 | And this happened in 1988 when a bomb went off on a plane over Lockerbie in Scotland | 这发生在1988年 当时苏格兰洛克比上空的飞机上 一枚炸弹爆炸了 |
| 51 | and the owner of the bag wasn't on board the flight. | 包的主人没有在飞机上 |
| 52 | Yeah, so it is for a really good reason, isn't it? | 是啊,所以这是一个很好的理由,不是吗? |
| 53 | It is to keep us safe. | 是为了保护我们的安全 |
| 54 | So we've got through the check in. | 所以,我们已经通过检查。 |
| 55 | Now we're on to security. | 现在我们去保安处了 |
| 56 | Yeah. | 对 |
| 57 | And we're going to leave our bag in the scanner in a sec. | 我们马上把包放在扫描仪里 |
| 58 | But first of all, we're going to walk through these gates where we have to stand like this, these body scanners. | 但首先,我们要穿过这些大门, 在那里我们必须站着,这些身体扫描仪。 |
| 59 | These ones or this sometimes. | 这些或这个有时。 |
| 60 | Sometimes it's like this, isn't it? | 有时是这样的,不是吗? |
| 61 | How do they work? | 他们怎么工作的? |
| 62 | So they're called millimetre wave scanners and basically they fire radio waves at your body | 因此,它们被称为毫米波扫描仪 基本上,它们发射无线电波 在你的身体 |
| 63 | and they have a wavelength that you can measure in millimetres, which is why they're called millimetre wave scanners. | 他们有一个波长,你可以用毫米测量, 这就是为什么它们被称为毫米波扫描仪。 |
| 64 | But the wavelength is really important because it's basically just the right size that these waves pass through your clothes. | 但是波长很重要 因为这些波从你的衣服里穿过 基本上只有合适的尺寸 |
| 65 | But they reflect off your skin and anything you have hidden underneath your clothes. | 但是它们会从你的皮肤里 以及你藏在衣服下面的任何东西中 反射出来 |
| 66 | And then these reflected waves are picked up by a detector and used to build an image of your body | 然后这些反射的波 被探测器拾起 用来建立你身体的图像 |
| 67 | and anything that you're hiding underneath your clothes. | 和你衣服底下藏的东西 |
| 68 | But the people working in security, I don't know if you've sort of seen over their shoulder, | 但是那些在保安部门工作的人 我不知道你有没有见过他们 |
| 69 | they basically get like a body and then an area will light up that needs further checks. | 基本上,他们得到像一具尸体, 然后一个区域会亮出来, 需要进一步检查。 |
| 70 | And that's when you end up with like an awkward ankle pat down. | 这时你最后会像一个尴尬的脚踝拍下来。 |
| 71 | Yeah. | 对 |
| 72 | A lot of people call them virtual strip searches because of the way that they can take off your clothes. | 很多人称他们为虚拟脱衣搜查,因为他们可以脱下你的衣服. |
| 73 | And there was actually an earlier iteration of these machines when they were first rolled out that could actually see you naked, right? | 这些机器最初被推出时 曾经有过一次重复 可以看到你裸体,对吧? |
| 74 | I mean, the tech itself can build an outline of your body in the sense that that is what it's doing. | 我的意思是,技术本身 可以构建一个轮廓 你的身体,从这个意义上说,它在做什么。 |
| 75 | It's firing particles or waves at your body and picking up on the reflections. | 它向你的身体发射粒子或波浪 并收集反射。 |
| 76 | But that isn't what the staff see. | 但工作人员不这么认为 |
| 77 | The staff just see here's an area of concern, check that out. | 工作人员只是看到这里有一个值得关注的地方, 看看这个。 |
| 78 | But yes, an earlier version of body scanner basically was unsuccessful | 但是,是的,一个早期的 车体扫描器基本上没有成功 |
| 79 | because people didn't want to get in them because they didn't want to be seen naked. | 因为人们不想进去 因为他们不想被看见裸体 |
| 80 | Fair enough. | 不错 |
| 81 | Fair enough, right? | 公平,对不对? |
| 82 | But all kinds of concerns about about privacy, right? | 但对于隐私的各种担忧,对不对? |
| 83 | And essentially someone being able to see underneath your clothes. | 基本上有人能看见你的衣服下面 |
| 84 | Yeah. | 对 |
| 85 | So at the same time as we're going through this body scanner, | 所以,与此同时,我们通过 这个身体扫描仪, |
| 86 | our bag is on the little conveyor belt and it's going through these scanners, which are x-rays, right? | 我们的包在小传送带上,它正在穿过这些扫描仪, 这些是X光,对不对? |
| 87 | So the really modern ones, which actually are in quite a lot of airports now, are CT scanners, | 所以真正现代化的, 实际上是在很多机场 现在,是CT扫描仪, |
| 88 | like the ones you see in a hospital, but they use x-rays. | 就像你在医院里看到的 但他们用X光 |
| 89 | So basically, you put your bag in the scanner. | 所以基本上,你把你的包 在扫描仪。 |
| 90 | It's fired at with x-rays from all different directions and different objects in your bag absorb, | 它用X射线发射 从所有不同方向 和不同的物体 在你的包吸收, |
| 91 | scatter or let different amounts of x-rays basically pass through. | 分散或让不同数量的X射线基本通过. |
| 92 | And those x-rays are picked up by detectors on the other side and used to build a 3D image of what's going on inside your bag. | 这些X光被另一边的探测器取出, 用来构建一个3D图像 显示你包里发生的事情。 |
| 93 | And as a general rule, more dense materials absorb more x-rays than less dense materials. | 而一般来说,密度较大的材料吸收的X射线比密度较低的材料多. |
| 94 | And this 3D image is often also colour coded so that the screeners, | 而这个3D图像也经常被编码成颜色,这样屏幕显示器, |
| 95 | which are the people, you know, sat looking at the inside of your bag, can sort of make sense of them more quickly. | 就是这些人,你知道,坐着看着你包里的东西, 可以更快地理解他们。 |
| 96 | So often orange is given to organic materials. | 因此,橙色常被赋予有机材料. |
| 97 | So that's things like clothes and food. | 这就是衣服和食物 |
| 98 | Green is often given to mixed materials. | 绿色常被赋予混合材料. |
| 99 | So that might be something like electronics. | 所以,这可能是 像电子的东西。 |
| 100 | And blue is often given to metals. | 而蓝色常被赋予金属. |
| 101 | So a gun, for example, could show up as blue. | 所以,比如枪,可以出现为蓝色. |
| 102 | And interestingly, I thought that this would be quite a fun job. | 有趣的是,我认为这是 一个相当有趣的工作。 |
| 103 | Like, I've always thought, you know, I could sit there and snoop on people's bags for hours. | 就像,我一直想,你知道, 我可以坐在那里 和窥探在人们的包上几个小时。 |
| 104 | I just thought it's quite fun. | 我只是觉得这很有趣 |
| 105 | But apparently, it's really easy to switch off. | 但很明显,它真的很容易关闭。 |
| 106 | So research basically shows that we get worse at picking up on things that happen less frequently. | 因此,研究基本上表明,我们更难发现 发生较少的事情。 |
| 107 | So that could be a screener looking for an explosive or a weapon. | 因此,这可能是一个屏幕 寻找炸药或武器。 |
| 108 | That could be a doctor looking for cancer in a scan. | 可能是医生在扫描中寻找癌症 |
| 109 | It's called the low prevalence effect. | 这被称为低流行效应. |
| 110 | And basically to avoid this, a lot of airports do something called threat image projection, | 基本上,为了避免这种情况, 很多机场都做了一些 所谓的威胁图像投影, |
| 111 | where they basically insert the image of something dangerous into random scans of people's bags to keep the screeners on their toes. | 将危险的东西的图像 插入到人们的袋子的随机扫描中 以保持屏幕上的脚趾 |
| 112 | So their kind of answers are recorded. | 所以他们的答案被记录下来。 |
| 113 | And if they're not picking up on these projected threatening images, then that data gets fed into training. | 如果他们不接收到这些预测的威胁图像, 那这些数据就会被输入训练中。 |
| 114 | They're looking for dangerous objects, these guns, explosive weapons, drugs, anything illegal, also liquids. | 他们正在寻找危险的物体,这些枪支,爆炸性武器,毒品,任何非法的东西,还有液体. |
| 115 | That's one of the most frustrating things, because a lot of the time you've got to get your liquids into these tiny little 100 millilitre bottles | 这是最令人沮丧的事情之一, 因为很多时候你必须 得到你的液体 进入这些小小的100毫升瓶 |
| 116 | and they've got to fit in a little plastic bag. | 他们必须装在一个塑料袋里 |
| 117 | Where did that rule come from? | 这个规则从哪里来的? |
| 118 | And can they actually tell the difference between different types of liquids when they put them in the scanner? | 他们把不同种类的液体放进扫描仪时 能分辨出它们之间的区别吗? |
| 119 | So this all comes from in 2006. | 所以这一切都来自2006年。 |
| 120 | There was basically a foiled liquid explosives plot where people were going to create an explosion on board a plane | 基本上有一个被挫败的液态炸药 在那里人们要制造爆炸 在飞机上 |
| 121 | that was taking off from Heathrow to somewhere in North America using liquids. | 从希思罗飞到北美的某个地方 用液体 |
| 122 | And the issue is, X-rays aren't very good at telling different liquids apart because they have really similar densities. | 问题是,X光片不太擅长分辨不同的液体, 因为它们的密度非常相似。 |
| 123 | So an explosive liquid could look very similar to a bottle of water, and there's not much we can do about that. | 因此爆炸性液体可以看起来非常类似于一瓶水,对此我们无能为力. |
| 124 | So to basically avoid liquids as a problem, this rule got introduced where you could only carry on a tiny amount, | 所以,为了避免液体作为一个问题, 这个规则被引入 在那里你只能继续 微小的数量, |
| 125 | so it's less threatening, and you often have to put them in a clear plastic bag so people can see exactly what's going on. | 所以威胁较小,你常常必须把它们放进一个清晰的塑料袋里,这样人们才能看清到底发生了什么。 |
| 126 | But yeah, that's a pain, and that is the one that always catches me out. | 但是,是的,这是一个痛苦, 而那是一个总是抓住我。 |
| 127 | I always have a water bottle hanging around in the bottom, and it's really embarrassing when you have to sort of, you know, go and take it back through. | 我总是有一个水瓶 挂在底部, 它真的很尴尬 当你必须排序,你知道,去 取回来。 |
| 128 | Yeah, you see all of the bottles stacked up. | 是啊,你看所有的瓶子都堆起来了。 |
| 129 | Yes, all the people practically drinking them. | 是的,所有的人几乎都喝他们。 |
| 130 | I'm always downing my water. | 常降水势. |
| 131 | Yeah, I'm so hydrated on every flight. | 是啊,我是如此水分 每一次飞行。 |
| 132 | I'm desperate for a wee. | 我渴望一个小。 |
| 133 | And sometimes you get brought over to do a manual search, and I've seen they get these like little ones with these swabs on the end, | 有时候你被带过来做手动搜索, 我见过他们得到这些 像小的,在结尾有这些块, |
| 134 | and they kind of put them through this little, they put them around your bag and all around the zippers, | 他们把它们放进这个小包里 放在你的包里 和拉链上 |
| 135 | and then they put them in this little machine and it beeps. | 然后他们把它们放进这台小机器里 它就响了 |
| 136 | What are they looking for there? | 他们在找什么? |
| 137 | So they're looking for explosives, and I think this bit of tech is just so clever because it can pick up on one billionth of a gram. | 所以他们在找炸药, 我认为这种技术太聪明了, 因为它能拿一亿分之一的炸药。 |
| 138 | So they are so, so sensitive. | 所以他们是如此,如此敏感。 |
| 139 | Yeah, really, really tiny amounts. | 是啊,真的,真的很小的数量。 |
| 140 | So what happens is, yeah, you get swabbed with a little bit of white cloth normally, then that gets put into a machine. | 事情是这样的,是的,你通常会用一些白布 来擦擦,然后放进机器里。 |
| 141 | It's called an ion mobility spectrometer, and the machine heats up the swab, | 它被称为离子移动光谱仪, 机器加热的swab, |
| 142 | and basically these tiny, tiny traces of chemicals evaporate and turn into a gas. | 基本上这些微小的化学物 蒸发成气体 |
| 143 | That gas is then ionized, which basically means turned into charged particles. | 然后,气体被电离化, 这基本上意味着变成电荷粒子。 |
| 144 | And these charged particles are passed through a tube which has an electric field across it. | 这些带电的微粒通过一个管子, 它有一个电场。 |
| 145 | And different particles move at different speeds through this tube, depending on their size, shape and charge. | 而不同的粒子通过这个管子以不同的速度移动,取决于它们的大小,形状和电荷. |
| 146 | So each particle is basically timed as it moves through the tube. | 因此,每个粒子在通过管子移动时基本上都是定时的. |
| 147 | And then it's compared to a database of known, threatening materials or compounds. | 然后与已知,威胁性材料或化合物的数据库进行比较. |

| 149 | you'd then be called for further testing or questioning. | 你会被叫去接受进一步测试或询问 |
