An analytical approach is adopted for the calculation of squeezed property of coherent light interacting with a nonlinear medium of inversion symmetry.

分析研究了相干光与具有空间反演对称非线性介质作用的压缩性质。

The property of symmetry can also be used to save a part of the computational effort required for matrix inversion or for a solution of equations.

对称的特性也可用来节省矩阵求逆中或求解方程中所需要的一部分计算量。
