涉及大气的力学问题 ,特别是关于做功方面的问题往往被忽视 ,其中像秤的读数、压木入水及抽水上岸等问题 ,近来纷纷被打造出炉 ,为此笔者想作点剖析 ,以求为相关问题的处理提供一些帮助 .1　受力问题剖析众所周知 ,大气压是由于地球周围空气的重力而产生 .一般在地面附近 ,平均 The mechanical problems involving the atmosphere, especially those related to work performance, are often overlooked. Problems such as readings on scales, pressing wood into water, and pumping water banks have recently been forged out. For this reason, the author wants to do some analysis to make it relevant. The treatment of the problem provides some help.1 Analysis of the Force Problem It is well known that atmospheric pressure is generated by the gravity of the air around the Earth. It is generally near the ground and the average
