The air around the particle heats up, but the hollow center of the beam stays cool.
粒子周围的空气受热,但光束的空心部分仍然保持原来的温度。

But when they are zapped with a beamof electrons from a particle accelerator, the polymer chains are desaturated.
但是,当它们经过粒子加速器发射的电子束扫描后,聚合分子链被去饱和。

There is no way that you could irradiate a crystal of nickel with a single beamof x-rays and get that circular ring pattern if the electron beam were behaving as a particle beam only.
