NEW SOLITARY WAVE SOLUTIONS FOR A CLASS OF FIFTH-ORDER NOLINEAR EVOLUTION EQUATIONS
一类五阶非线性演化方程的新孤波解

The exact explicit solitary wave solutions for a class of fifth-order nonliear evolution equations are obtained by using a homogeneous method. Particular important cases of the equation, such as Kaup-Kupershmidt, Caudrey-Dodd-Gibbon-Sawada-Kotera and fifth-order KdV equations can be solved by this method.
