| 摘 要： | 文章证明了当刚体相对于质心的力矩为零时,则相对于空间任一点力矩均为零,从而可以用多选一个参考点的方法代替原平衡方程中的一个分量方程,为解决刚体平衡问题提供了新的思路,并以一道典型刚体平衡问题为例加以验证。

| Abstract: | This paper proves rigid body' moment is zero in relation to the space at any point when the body's center of mass' moment relative to zero,so that the election can be used as a reference point instead of a component equation of the original balance equation.It addresses the question of the rigid body balance with a new idea,and illustrates it with the example of a typical rigid body balance. |
