摘　　要：通过对转动惯量取极小值的方法求得平面刚体重心的解析解 。Based on the way of obtaining the minimum solution of moment of inertia, the analytical solution of the center of gravity of plane rigid body is acquired. According to optimization theory, the numerical computing method for finding the gravity center of plane rigid bodies is presented by searching the minimum solutions of moment of inertia.
