非惯性参照系中的Lagrange方程

Lagrange Equation in Uninertia System

从非惯性参照系中的惯性力表达式出发，找出与之相对应的广义势函数 U′，进一步写出与之相对应的类Lagrange 函数表达式 L″，从而推导出在非惯性参照系中的第二类 Lagrange 方程和保守力系的 Lagrange 方程，并通过实例说明在非惯性参照系中 Lagrange 方程的应用，从分析力学的角度提出了求解非惯性参照系中的动力学问题的一种方法。

A generalized potential function U'has to be found from the formula of inertia force in noninertia system and the analogous Lagrangefunction L”,then we get the second type Lagrange equation in noninertia system and the Lagrange equation in a potential field,which is anothermethod of answermg dynamic problems in noninertia system of analytic mechanics.Some examples is discussed about the application of the La-grange equation in noninertia system.
