天文大气折射级数展开式的系数

摘要

Using the theoretical relationship satisfied by atmospheric parameters between two points in the ray path,the influence of the atmosphere layer to astronomical atmospheric refraction was obtained.It not only considered the contribution of electronic displacement polarization of the dry air to astronomical atmospheric refraction,but also considered contribution of electronic displacement polarization and dipole steering polarization of water vapor.The integral representation is given,it does not depend on atmospheric distribution models,and it could adapte the calculation of different directions and meet the demand for high-precision.%利用射线路径上两点之间大气参数满足的理论关系,给出了大气对天文大气折射的影响,不但考虑了干大气,而且考虑了水汽电子位移极化和偶极子转向极化对天文大气折射的贡献.该积分表达式不依赖于大气分布模型,适应不同方位的计算和高精度的需求.
