To the electron, the corresponding system is the positron, which was observed after the prediction in cosmic ray experiments by Anderson in 1932.

对电子来说，与其相对应的是正电子，后者被安德森于1932年在宇宙射线实验中发现。

So rather than calling this an electron beam, this was called a cathode ray.

因此我们最好别叫它电子束，而是阴极射线。

It is an electron beam. In the 1890s, the latter part of the 19th century a very fashionable word was "ray."

那是个电子束，在十九世纪九十年代，就是19世纪末,一个很时髦的词汇-“光线“
