英语释义

1. an effect due to the wavelike nature of electrons and observed when a narrow beam of them upon passing through a very thin layer of a material (such as a metal crystal) is deflected in particular directions and if allowed to fall on a fluorescent screen produces a pattern of light and dark areas, the pattern formed by these areas being characteristic of the material traversed
