摘要
本文从晶体对称性出发,在一定近似条件下利用群论方法,不作关于能带具体计算,就能得出晶体的电子态和能量的一般性质,其方法较为简明而又系统。
on the basis of the symmctry or crystal,tilldcr the fisl dcgree approxima-tion,this paper USeS group theory mcLhod to obtain the generaI qtiatlos of eleetron stateand CncCrgy of crystal without concrete calculation about cncrgy band.Discussions aboutthe resuILs are convcnicnt in physics, and the method is concisc and systmatic.
