通过引入一个变换,将变系数组合kdv—Burgers方程约化为新的简洁形式的方程,由齐次平衡原则求出了该方程的Auto—Backlund变换和类孤子解.
By use a new transformation,the variable coefficient combined Kdv- Burgers equation reduces to a new simplified form equation. And based on the homogeneous balance principle, Auto- Backlund transformation and several exact solitons- like solutions for the variable coefficient combined Kdv - Burgers equation are obtained.
