Truncation and Approximate Solution for Nonlinear Dynamic System in Two Dimensions

通过对二维非线性动力系统的截断近似,使得二维非线性动力系统由一组方程来表达.本文用一个特例解出方程组,说明了二维线性动力系统向圆映象的转换,并且表明了这种方法的有效性.

Nonlinear dynamic system in two dimensions is expressed by a group of equations by approximately Truncating nonlinear dynamic system in two dimensions. A group of equations is solved for an example, the translation from nonlinear dynamic system in two dimensions to a circle mapping is discussed, and the effectiveness of the method is also showed.
