摘要
借助群的概念和性质,得出一阶非线性微分方程组的解对复合运算构成群,因此,无论是一阶线性微分方程组还是非线性微分方程组,它的解对相应的"乘"法都具有指数性质.
In this paper,by means of the concept and viewpoint of group,we obtain that the solutions of first order non-linear ordinary differential equation system form a group under composition;thereby,the solutions all satisfy the rule of the exponent operation under corresponding " product ",whether for first order linear system or non-linear system.
