    The dynamic applications of these models are briefly discussed. The dynamic equations of visco-elastic composite structure are second order linear Volterra differential-integral equations. It is difficult to analyze the modes of composite structure by using Volterra differential-integral equations.

    2) With Green function dislocation equation in anisotropic simple-cubic crystal has been derived rigorously using crystal dislocation analytic theory on the base of crystal dynamics considering the central force interact during the first-nearest-neighbor atoms and the second–nearest-neighbor atoms and the angular force interact between the first-nearest-neighbor atoms. The universal structure of dislocation equation that the equation was nonlinear differential-integral expression has been discovered.
    2)利用基于晶格动力学的晶体位错全离散解析理论,考虑最近邻原子间和次近邻原子间的中心相互作用以及最近邻原子间的角向相互作用,考虑晶格的离散效应,利用格林函数方法严格推导出了准连续近似下各向异性简立方晶体中的位错方程,与已有的位错方程相比表明了位错方程具有普适结构:非线性的微分积分方程;
