关于大气压强可以有两种解释:第一;由于地球对空气的吸引作用,空气压在地面上,就要靠地面或地面上的其他物体来支持它,这些支持着大气的物体和地面,就要受到大气压力的作用.单位面积上受到的大气压力,就是大气压强;第二;可以用分子动理论的观点解释.因为气体是由大量的做无规则运动的分子组成,而这些分子必然要对浸在空气中的物体不断地发生碰撞.每次碰撞,空气分子都要给 There are two explanations about the pressure of the atmosphere: first, because of the attraction of the Earth to the air, when the air is pressed to the ground, it needs to be supported by other objects on the ground or on the ground. The objects and the ground that support the atmosphere, Is subject to atmospheric pressure. The atmospheric pressure on unit area is the pressure of the atmosphere; secondly, it can be explained by the theory of molecular dynamics. Because gas is made up of a large number of molecules that make random movements, these molecules must A constant collision occurs with objects immersed in the air. Each collision, air molecules are given
