Then the equations of elastic problem are imported into the hamilton system in the plane right - angle coordinate system and a new symplectic numerical method , the symplectic difference method of elasticity in hamilton system , is put up based on the mixed equation of elastic problem . the arithmetic of the method is programmed and used in the solution of three problems of elasticity , which is sheet problem , simply girder problem and deep girder p roblem that is pressed equally in the right - angle coordinate system
然后在平面直角坐标系下将弹性力学问题引入到hamilton体系中来，针对弹性力学混合方程建立了一种新的辛型数值计算方法? ?基于hamilton体系的弹性力学辛差分方法；并且编程实现了该方法的算法结构，计算了三个具体的算例：受均布载荷的薄板问题、简直梁问题和深梁问题。
