| 摘 要： | 对虚位移原理表述形式存在争议的问题进行了详细的讨论,首次提出了在虚位移原理的表述中,其充分条件和必要条件所要求的初始条件和约束条件有很大不同原理的充分性要求质点系的约束必须是定常、理想约束,且初始条件是质点系静止;而原理的必要条件则只要求约束是理想的.

| Abstract: | A detailed discussion about the debating questions of principle of virtual displacement was given It is put forward for the firist time that the fully condition and necessary condition of the principle have the different demands on intial status and constraint conditions The fully condition of the principle demands that the system of particles must be static initially,and the constraint of the system must be steady and idea But the necessary condition only demands that the constraint of the system is ideal |

| Keywords: | principle of virtual displacement constraint conditions intial status |
