初二物理“液体的压强”一节,通过几个实验总结出:“液体内部向各方向都有压强,压强随深度的增加而增加,但在同一深度,液体向各个方向的压强相等。” 就教材中安排的几个实验来看,完成“在同一深皮,向各方向的压强相等”的实验是较困难的,其原因就是难以把握住“同一深度”。怎样解决这一实验中存在着的问题呢?
The first two physical “Liquid pressure ” section, concluded through several experiments: “The liquid inside has pressure in all directions, the pressure increases with the depth increase, but at the same depth, the pressure of the liquid in all directions Equally.” With regard to several experiments arranged in the textbooks, it is more difficult to complete the “equally deep skin, equal pressure in all directions” experiment. The reason is that it is difficult to grasp the same depth. . How to solve the problems in this experiment?
