液体由于难压缩而具有大小不变传递压强的特性；又由于流动性不仅对其容器底产生压强，且对器壁产生压强；液体产生压强的原因是由于液体具有重；如图1，户一F／S一’G／S二mg／S一（尸V）g／SZP（Sh）g／s一Pgh即液体产生压强公式P—Pgh这里提出两个问题，一是液体产生的任强?
Due to the fact that the liquid is difficult to compress, it has the characteristic of transmitting pressure at the same size; because the fluidity not only generates pressure on the bottom of the container, but also generates pressure on the wall of the container; the reason for the pressure generated by the liquid is that the liquid has heavy weight; F/S A’G/S 2 mg/S I (corpse V)g/SZP (Sh)g/s Pgh is the pressure generated by the liquid formula P-Pgh Two questions are raised here.
