非线性Schrodinger方程的流不变集

Invariant Subset of the Flow for Nonlinear SChrdinger Equation

本文采用“非线性化”方法，对非线性Ｓｃｈｒｄｉｎｇｅｒ方程的Ｌａｘ组进行非线性化。非线性化后。

In this paper,by the“nonlinearization method”the Lax system for nonlinear Schrodinger equation is nonlinearized.After the nonlinearization,the solution variety of the spatial part of the Lax system is an invariant set of the S-flow detemined by its time part.
