帕斯卡定律是：封闭容器中的静止流体的某一部分发生的压强变化，将毫无损失地传递至流体的各个部分和容器壁。

The Pascal's law is: Seals up intensity of pressure change which in vessel's fluid at rest's some part occurs, will not lose the transmission to the fluid each part and the vessel wall.

该公式源自一个流体力学原理，即描述静流体中压力与深度关系的帕斯卡原理，所以只适用于流体。

This formula stems from a fluid mechanical principle, the Pascal's principle, describing the relationship between pressure and depth in static fluid. This formula is applied to fluid material only.
