In the systematic system, a direct method solution for symplectic eigenvalue problems is put forward. The symplectic method updated the solving system of the viscoelasticity to a new platform.
在辛体系下建立了一种辛本征解直接方法，将粘弹性力学求解方法和思路上升到一个新的平台。

Therefore, it is necessary to study numerical methods which preserve the symplectic structure of the Hamiltonian system.
因此，研究保持哈密尔顿系统的辛几何结构特征的数值方法是必然的。
The symplectic conservative perturbation for a transfer symplectic matrix should be based on the canonical transformation method.
辛矩阵只能在乘法群下保辛，故传递辛矩阵的保辛摄动必须采用正则变换的乘法。
The sum of two symplectic matrixes is not symplectic conservation. The product of two symplectic matrixes is symplectic conservation.
两个辛矩阵之和不能保辛，两个辛矩阵的乘积仍是辛矩阵。
