应用双变换构造可积的Lagrange-D'Alembert型微分方程

Applying Double-transform to Construct a Integrable Largrange-D' Alembert Type Differential Equation

本文在文献的思想启示下,先提出一个引理,借助此引理,再应用双变换法构造出可积的拉格朗日──达朗贝尔（Lagrange-D'Alembert）型微分方程。

Under the idea including in literature revelation, this paper presents a lemma at first;Based on this lemma and applying double-transform method, the author constructs a integrable Largrange-D' Alembert type differential equation, meanwhile, and derives a integrable Largrange-D' Alembert type differential equation's parametric general integral calculus expression.
