针对对流层延迟问题，考虑测量时对流层的折射率，采用标准模型计算对流层修正概率。经大量实验研究得到对流层延迟修正模型，它可以减少坐标测量误差约30％，海拔测量误差约40％。
針對對流層延遲問題，攷慮測量時對流層的摺射率，採用標準模型計算對流層脩正概率。經大量實驗研究得到對流層延遲脩正模型，它可以減少坐標測量誤差約30％，海拔測量誤差約40％。

The paper considers the possibility of correction of zenith tropospheric delays ,and calculates it with the standard model ,which takes into account the values of the refractive index of the troposphere at the time of measurement .Based on the experimental research ,this empirical model of correction for zenith tropospheric delays can reduce the measurement er -ror of coordinates to about 30% and altitude to about 40% .
