Cosinor analysis uses the least squares method to fit a sine wave to a time series. Cosinor analysis is often used in the analysis of biologic time series that demonstrate predictible rhythms. This method can be used with an unequally spaced time series. Follows cosinor analysis of a time series as outlined by Nelson et al. Methods for Cosinor-Rhythmometry Chronobiologica. 1979.

朱邦芬只保留电子-声子互作用算符 对角项，把非对角项作为微扰处理； 原则上，不同的电子态对应于不同的晶格平衡位置；通常计算固体的振动性质时，假定电子处于基态。 (Zhu bonfim retain only electronic- phonon interaction diagonal operator, the diagonal of the non-perturbative as processing in principle, different electronic states corresponding to different lattice equilibrium position usually calculate the vibration of the solid nature, it is assumed that e in the ground state.)
