摘　　要：文章从劳厄发现晶体X射线衍射的前因后果谈起.劳厄的这个发现产生了两个新学科,即X射线晶体学和X射线光谱学.文章中还回顾了布拉格父子对开展这两个新学科研究所作出的卓越贡献,并略述了X射线晶体学所产生的深远影响.This review begins with the background of Laue＇s discovery which gave rise to two branches of science, X ray crystallography and X-ray spectroscopy. It also covers the contributions made by W. H. Bragg and W. L. Bragg to these two areas, and will end with reviewing some of the far-reaching influence of X-ray crystallography.
