In addition to studying molecules and making molecules, some chemists Tim Swager want to detect molecules, and a chemist who likes to detect molecules TNT is Tim Swager. So, Tim Swager's lab has designed sensors that detect vapors, Fido and so they will detect TNT, for example.

除了研究和制备分子,有些化学家想要探测分子,其中的一位就是，他的实验组设计了用来探测蒸汽的感应器,可以用来检测比如说,而且他把化学应用到这个机器人手臂里，他们叫它。

And so, he has put this chemistry to use in this robotic arm and they call it Fido, because often dogs are the creatures that have to go out and detect these things, and it's not a great job if you're a dog to be sent out to see whether there was an explosive and discover yes, there was, a little bit too late.

因为通常都是派狗去检查这些东西,这个不是个好工作，如果你是一只狗,被派去检查是否有爆炸物，然后你发现有,那就来不及了,所以用机器手检查化学物质。

They bring it in and they say, "Oh, Fido's dead, Fido's dead, but what's for dinner?"

他们把它捡回来，说，“Fido死了，Fido死了，晚餐吃什么？“
