提出了求解非线性发展方程精确解的负幂指数展开法.利用这一方法,借助计算机的符号计算,求得了若干非线性发展方程的有理函数解.
Negative exponent series expansion method was proposed to construct the exact solutions of some nonlinear evolution equations. It is shown that exact rational function solutions of some nonlinear evolution equations were obtained by this method.
