变质量非完整系统相对于非惯性系的第一积分与积分不变量

First lntegrals and lntegral lnvariants for Variable Mass Nonholonomic System in Noninertial Reference Frames

本文给出了变质量非完整系统相对于非惯性系的第一积分存在的条件，建立了这类系统的正则方程和变分方程，证明了由第一积分可直接构造系统的积分不变量，并给出一系列推论和一个例子．

The first integrals and their conditions of existence for variable mass nonho-lonomic system in non-inertial reference frames are obtained.and the canonical equations and the variation equations of the system are extended.It is proved that using the first integral we can construct the integral invariant of the system,Finally,a series of deductions and an example are given.
