If there were no voltage on the plates, we would expect everything to be over here in some negative value falling.

如果板子上没有速度，这些可能都在这,都是负值下降的。

And I am able to vary the voltage on the plates making this for argument's sake negative and this for argument's sake positive.

我可以改变两个板子上的电压,为了论证，这个是负电,这个是正电。

Go ahead and just pinch the metal plates and watch your eyes 'cause these do--things do have little springs.

挤压这些金属片,你会注意到没什么弹性。

So, when the voltage difference between the plates is zero, or when we just don't have the plates there at all, the cathode rays are not bent, they just go right in a straight line, and they can be detected on this screen.

拐弯来测试它们是否带电,当两板之间电压为零，或者根本就,没有这两个板时，阴极射线是一条直线,它可以在屏幕上。

The technology that they use and really there's quite a lot of technology here starting from the plates that you grow them in turn out to be engineered so they have the right properties.

这个过程需要使用的技术,确实非常多,从设计培养细胞用的培养皿,到工程化培养出有合适属性的细胞

And then I could put a couple of plates and I could raster the beam so that when I am looking here,the beam goes back and forth about 80 times a second.

然后我放了两个感光片,我可以检测到光束所以,当我观察时,电子束以每秒80次的速度来来回回了。

Can anyone not see it? Does anyone need -- actually I can't even tell if you raise your hand. So ask your neighbor if you can't see it and get one of the plates if you're having trouble seeing with the glasses. So this should match up with the spectrum that we saw.

有人没看到的吗？,有人需要-实际上你们举手我也看不见,看不到的话就问你们周围的人借个小片,如果你们用眼镜看不到的话,这应该和我们看到的光谱是吻合的。

that the negative particle travelled - it was deflected much, much further by those plates, what he could also assume and make the conclusion of is that the mass of that negative particle is actually larger or smaller?

因为他发现负电粒子,运动了很远,它被两块电板偏转了,非常非常远,所以他给出的结论是,负电粒子的质量,是比较大还是比较小？

You've probably seen agar plates, if you smear a solution that's contaminated with bacteria on it, then that bacteria will grow on this agar rich medium and you'll get many, many copies of the bacteria that you've smeared at low density onto the plate.

你们大概见过琼脂培养基,如果将有细菌的溶液涂抹在培养基上,细菌就会在富含琼脂的培养基上生长,你会得到许多许多细菌,即使你只涂抹了低浓度溶液

And, I mean, for example in France-- and if this ever disappears I'm going to be one unhappy guy--the license plates, the last numbers of the license plate tells you where people are from.

我的意思是,举例来说,在法国,如果这件事取消的话,我就会十分不高兴的,它就是汽车牌照,牌照上的最后几位数告诉你,这个人来自哪里

耶鲁公开课 - 1871年后的法国课程节选

And what we did was he put two detection plates on either side of these cathode rays, and when he put a voltage difference between these two plates, he wanted to see if he could actually bend the rays and test if they're actually charged or not.

但没有实验证明这件事,这就是Thomson所做的，它在阴极射线旁边放两块探测板,他想通过看当他,在两板之间加上电压后,阴极射线是不是会。
