摘要
本文讨论了二阶非线性方程在自变量与因变同时变换下的不变量及其应用，将文献中两种相互独立的变换方法有机地揉合一起。从而推广了文献中的结论，扩大了应用范围。
The invariant of two-order nonlinear equation under the conditions of simultaneous transformation of independent variable and dependent variable and its application are discussed and the two independent alternate methools in the document are combined organically ,thererefore,the conclusion in the document is popularized and the application is extended.
