摘　　要：孤立子(孤立波)是一种广泛存在的非线性现象。由于等离子体孤立子理论能够解释很多实验现象,因此该理论逐渐发展成非线性等离子体物理中不可或缺的一部分。本文利用数学软件Matlab对等离子体中经典的两种孤立子——离子声波孤立子和朗缪尔孤立子进行了数值求解,验证了孤立子的几条固有性质,同时给出了相关结论。Solitary waves are a type of nonlinear phenomenon that exists widely in nature.Plasma soliton theory can explain many phenomena observed in experiments and space,and it has become an important part of nonlinear plasma physics.This paper used the mathematical software Matlab to numerically solve the two classical solitary waves in plasma-ion acoustic wave solitons and Langmuir solitons,verifying several inherent properties of solitary waves,and at the same time gives the correlation from the numerical results in conclusion.
