本文主要评述最近三、四年间国外陀螺系统动力学的进展情况。 “陀螺系统”可以是质点系,也可以是一个刚体或刚体系。陀螺系统是一个受到陀螺力作用的力学系统,也就是在系统的运动微分方程中含有陀螺项。所谓陀螺力是这样一些力,它在系统的任何无穷小真位移上所作的功之和等于零。所以陀螺系统既可以是具 This article mainly reviews the progress of gyro system dynamics in foreign countries in the recent three or four years. “Gyro system” can be a particle system, it can be a rigid or rigid system. The gyroscope system is a mechanical system that is affected by the gyroscopic force, that is, it contains the gyroscopic elements in the system’s differential equations of motion. The so-called gyro-force is the force that makes the sum of the work done on any infinitesimal real displacement of the system equal to zero. So the gyro system can be a tool
