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射线谱学和X射线晶体学 .文中还回顾了布拉格父子对这两个新学科所作的重大贡献 ,并阐述了X射线晶体学的深远影响 .A review is first given of the background of Laue′s discover which gave rise to two branches of science, X-ray spectroscopy and X-ray crystallography. This is followed by a review of the remarkable contributions of Bragg, father and son to these two areas, and a discussion of the far-reaching influence of X-ray crystallography.
