我们回顾了固体光学常数的计算所带来的问题和为此目的的运动方程方法的适应。在过去的晶体材料的研究采用布洛赫定理，但非晶材料和表面的对称性通常不能用来减少计算到可管理的比例。运动方程方法避免了在计算晶体和非晶半导体的大型结构模型的线性和非线性光学性质时对角化的需要。这种方法应该提供一个实用的技术来计算大系统的光学特性。
We review the problem posed by the calculation of the optical constants of solids and the adaptation of the equation-of-motion method for this purpose. In the past crystalline materials were studied by employing Bloch's theorem, but for amorphous materials and surfaces symmetry cannot generally be used to reduce the computation to manageable proportions. The equation-of-motion method avoids the need for diagonalization in calculating linear and nonlinear optical properties for large structural models of both crystalline and amorphous semiconductors. This approach should offer a practical technique for calculating the optical properties of large systems.
