The symplectic conservative perturbation for a transfer symplecticmatrix 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。

And a numerical algorithm for constructing a random symplectic orthogonal matrix is put forward.
给出了一种构造完全随机的正交辛矩阵的数值实现方法。

In this paper, the author gives a kind of expression of symplectic matrices by using the result that any matrix on a field is a product of two symmetric matrices.
