在学习物理的过程中，对一些概念、公式或定律，我们首先应掌握它们的实质，捕捉需要记忆的特点，然后逐步加工整理，使之条理化、系统化．这样，便于在理解中进行记忆，在记忆中进行理解．例如学过液体内部的压强公式p＝ρgh之后，我们可以对照固体的压强公式P＝7加以‘“’” In the process of learning physics, we must first grasp the essence of these concepts, formulas or laws, capture the characteristics that need to be remembered, and then gradually process them to make them systematic and systematic. In this way, it is easy to remember in understanding and to understand in memory. For example, after learning the pressure formula of liquid inside p=ρgh, we can use the pressure formula of solid as P=7 to ‘”’
