坐标摄动 meaning in English

coordinate perturbation

In the second chapter , the traveling wave solution of klein - gordon equation has been obtained at first , then the asymptotic solution of klein - gordon equation with initial condition has been acquired , at last a kind of klein - gordon equation ' s stability has been discussed
第二章首先将坐标摄动思想和参数变换思想结合起来求出klein - gordon方程的行波解，再将改进l - p方法直接应用到求解klein - gordon方程的直接渐近解，最后用多尺度法讨论了其稳定性。
