因此我们最好别叫它电子束，而是阴极射线。

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

食品通过短暂地暴露在x射线、γ射线或电子束来进行辐照杀菌。

Food is irradiated by brief exposure to X-rays, gamma rays or an electron beam.

电子束半导体探测器的测量精度易受到射线的能量、 剂量率、入射方向和环境温度等条件的影响。

The measurement accuracy of electron beam by using semiconductor detector is easily affected by beam energy, dose rate, beam incidence direction, environment temperature etc.
