B-MKdV方程和B-MBBM方程的一类孤波解

A Class of Solitary Wave Solutions for the B-MKdV Equation and the B-MBBM Equation

本文求出了B-MKdV方程和B-MBBM方程的一类精确孤波解。B-MKdV方程的这类解可看成MKdV方程的一个扭状孤波解加上一个常数。B-MBBM方程的这类解可看成MBBM方程的一个扭状孤波解加上一个常数。

In this paper, a class of solitary wave solutions for the B-MKdV equation and theB-MBBM equation have been obtained. The solution for the B-MKdV equation canbe regarded as the sum of a Kinky solitary wave of the MKdV equation and a certainconstant, the solution for the B-MBBM equation can he regardedas the sum of a Kinkysolitary wave of the MBBM equation and a certain constant.
