A simple fast method in finding the analytical solutions to a class of nonlinear partial differential equations
求一类非线性偏微分方程解析解的一种简洁方法

By introducing,a new transformation and selecting appropriate trial functions ,nonlinear partial diff erential equations can be converted to algebraic equations,and their related coe f ficients can be easily determined by making use of the method of undetermined coefficients. Finally,the analytical solutions to a class of nonlinear partial di fferential equations are successfully derived. One can easily see that this meth od used herein is particularly simple.
