摘　　要：在讨论了一维晶格振动的色散关系和晶格热容的基础上,以二维正方晶格为例,计算了最近邻近似下的色散关系.其数值计算结果用Matlab作图表出.based on the two-dimensional square lattice for example,we analyze the relations of the closest atom approximate dispersion,which is based on the discussion about the dispersion relation of one-dimensional lattice and lattice heat capacity.The numerical result has been presented by Matlab.

关 键 词：二维正方晶格 最紧邻 频率色散
