φ~5模型的孤立子波解研究

STUDY OF SOLITARY WAVE SOLUTIONS OF THE 5 FIELD

非线性科学的一个主要特征是孤立子解的存在。５模型是迄今人们较少涉及的一个模型。本文利用一个具有相当一般限制条件的非线性Ｋｌｅｉｎ－Ｇｒｏｒｄｏｎ场作为辅助场，将５模型的某些孤立子解问题转变为讨论一个非线性常微分方程。

The existence of the solitary wave is an important property in the nonlinear science.The 5 field is one that few people have dealed with.In this paper,we use a nonlinear Klein Gordon field with a quite general constrained condition as an auxilialy field and obtain some special types of solutions of the 5 field by solving an ordinary nonlinear differential equations.
