适应于大气折射研究的压高公式

Restudy on the Barometric Height Formula in Atmospheric Refraction Theory

大气压力随高度的分布模型是大气折射理论研究的基础。本文研究了大气折射理论中有关大气参数之间的理论关系,指出目前文献给出的压高公式是不完备的;同时,以位势地心距取代几何地心距,给出了干洁大气、水汽和湿大气的压高公式,以及它们在等温大气层和多元大气层中的具体表述。结合标准大气模型和大气分层结构的特性,给出了压高公式在不同情况下的具体应用。

Atmospheric refraction is an important issue in the astronomy and geodesy , in which the atmospheric pressure distribution model along with altitude is the basis of theoretical research on atmospheric refraction.This paper studies theoretical relationship among atmospheric parameters in atmospheric refraction theory , and points out that the Barometric Height Formula given by current literatures is not complete.At the same time , by replacing geopotential geocentric distance with geometrical geocentric distance , Barometric Height Formule of dry air , water vapour and damp atmosphere as well as their specific statement in isothermal atmosphere and polybasic atmosphere are given.Combined charcters of normal atmosphere model and it ’ s layered structure , specific application of Barometric Height Formula in each case is given.
