摘要
运用经典摄动理论中的多重尺度法和数学物理方法中常用的拉普拉斯变换法，求解了ｓｉｎｅＧｏｒｄｏｎ方程的微扰问题，得到了不含长期项的一级修正解和孤子参数随时间的缓慢变化关系．
Abstract Making use of the method of multiple scales from the
classical perturbation theory and the general method of Laplace transformation from the
mathematical physics methods, we have solved the perturbation problem for sine Gordon
equation, and obtained the fist order correction containing no secular terms, as well as the
parameters slowly varied with time.
