为了构造非线性发展方程的无穷序列类孤子精确解, 发掘第一种椭圆辅助方程的构造性和机械化性特点, 获得了该方程的一些新类型解和相应的 Bcklund变换. 在此基础上利用符号计算系统Mathematica构造了Nizhnik-Novikov-Vesselov方程的 无穷序列类孤子精确解, 包括无穷序列光滑类孤子解、 无穷序列类尖峰孤立子解和无穷序列类紧孤立子解.To construct the infinite sequence soliton-like exact solutions of nonlinear evolution equations and develop the characteristics of constructivity and mechanization of the first kind of elliptic equation, new type of solutions and the corresponding Bcklund transformation of the equation are presented. Based on this, infinite sequence soliton-like exact solutions of Nizhnik-Novikov-Vesselov equation are obtained with the help of symbolic computation system Mathematica, which includes infinite sequence smooth soliton-like solutions, infinite sequence peak soliton-like solutions and infinite sequence compact soliton-like solutions.
