本课从晶体结构和张量分析出发，讨论晶体的性能与结构的关系，并论及晶体的各种效应及其应用。所论晶体的性能主要涉及热学、力学、电学和光学，对磁学涉及较少。主要内容包括32种晶体点群的推演及图示，二阶对称张量的示性面与主轴化，介电特性，电光效应，二阶非线性极化效应，虎克定律，压电效应，声表面波，晶体的物性方程等。

Beginning from crystal structure and tensor analysis, this lecture discusses the relation between properties and structures of crystals, as well as various physics effects and their applications. The mentioned properties are mainly thermal, mechanical, electrical and optical properties of crystals. Few magnetic properties is involved. The main contents include the deductions and the schemes of 32 point groups of crystal, the quadric and principal axes of a symmetrical second-rank tensor, dielectric properties, electro-optical effect, second-order nonlinear electric polarization, Hook’s law, piezoelectricity, acoustic surface wave and the equations of crystal properties, etc.
