【摘要】 利用矩方法对非均匀等离子体中修正的Zakharov方程进行了求解，得到了孤子解，并讨论了各种阻尼对孤子运动的影响．同时考虑各种扰动的影响后，得出了一个关于孤子运动变化的新特征．更多还原

【Abstract】 The modified Zakharov equations for inhomogeneous plasmas is analyzet on thebasis of a moment method. Soliton solution is obtained. And the relations between the dtherent damping and motions of the soliton are discussed. Considering all these pertubations, anew feature is found for the velocity of soliton.更多还原
