| 摘 要： | 通过典型实例从四个方面详细地分析了总反力对摩擦圆的相切方向与机构输出力（力矩）之间的关系，提出了一个简捷有效的总反力相切方向判定法测：总反力对摩擦圆的相切方向一定在使机构输出力矩最小或与机构速度夹角最大的方向上。

| Abstract: | After a relation is fully analyzed between the tangency direction of general opposite force to frictional circle and the output foroe(or moment of force) form four respects through topical examples, a simple and quick judging method is proposed to certain the tangency direction of general opposite force to frictiona] circle, or, the tangency direction of general opposite force to frictional circle must be in the direction of the smallest moment of force output by mechanism or in the direction of the biggest angle between general opposite force and output velocity. |
