重力场中大气温度和压强的探究
Exploration of atmospheric temperature and pressure in gravity field
摘要
Abstract
The formulas for atmospheric temperature and pressure are derived respectively within the variation of gravity acceleration with height based on Van der Waals gas model,and compared with the ideal gas model with the variation of gravity acceleration with height and the Van der Waals gas model with constant gravity acceleration.The results indicate that the three models have relatively small differences in describing atmospheric temperature,while the Van der Waals gas model considering the variation of gravity acceleration with altitude has better improvement in describing low altitude atmospheric pressure.In addition,the Van der Waals gas model with the variation of gravity acceleration with height is closer to the real situation.Using this model not only helps to simplify physical problems,but also depicts the main characteristics of atmospheric temperature and pressure to a certain extent.关键词
