固体对支承它的物体的压强可用公式：压强＝压力／受力面积来表示。液体到处流动，它的压强有什么特点，是否也像固体一样，也能找到一个适用的公式呢？初中物理课本第一册有研究液体的压强实验，采用压强计、水、盐水、烧杯、刻度尺等器材，可以成功地完成实验，但是有些不足? The pressure of a solid on the object that supports it can be expressed by the formula: pressure = pressure/force area. The flow of liquid everywhere, the characteristics of its pressure, whether it is like a solid, can find a suitable formula? In the first volume of the junior high school physics textbook, there are pressure experiments to study liquids. Pressure gauges, water, salt water, beakers, scales, and other equipment can be used to successfully complete the experiments.
