如何通过物理模型寻求数学模型从而找出数学方法并解决固体物理问题是固体物理学学习中的重要的内容.本文就通过简单的数学模型清晰的分析理解晶格及晶格振动的的一些基本概念；通过晶体比热容物理模型的改进解决低温下与实际不符的问题；通过广义积分、δ函数、傅里叶级数等特殊函数方法对固体物理学中的费米、电子比热容、能带进行了求解,并分析了三种物理量各自蕴含的物理含义.

Answer 1

How to through physical model and mathematical model to seek out and solve mathematical methods of solid physical problems in the study of solid state physics is an important content. This paper through the simple mathematical model analysis of the grid work and understand clearly the lattice vibrations some basic concepts; Through the crystal heat capacity improvement of physical model to solve let under low temperature and the actual problem not; Through the generalized integrals, the delta function, Fourier series, and other special function method to solid state physics, the electronic heat capacity let, Fermi band are solved, and analyses three kind of physical quantity of the physical meaning each contains.
