关于大气压强,初中物理教科书中如是说:“大气受重力作用而产生的压强叫做大气压强,简称大气压.”而高中物理教材对“大气压”未见有详细确切的说明.因此对大气压的认识有一部分人产生了误区.本文就常见的几个问题加以解释,以便走出误区,正确理解大气压的概念,更好地把握教材.
With regard to atmospheric pressure, the junior high school physics textbook says: “The pressure produced by the action of gravity on the atmosphere is called atmospheric pressure, or simply atmospheric pressure.” The high school physics textbook does not have a detailed description of “atmospheric pressure.” Therefore, there is a knowledge of atmospheric pressure. Some people have misunderstandings. This article explains several common problems in order to get rid of misunderstandings, correctly understand the concept of atmospheric pressure, and better grasp the teaching materials.
