摘　　要：给出了对流层电波折射误差修正应用中的霍普菲尔德大气模型和精确大气模型.经过仿真可见霍普菲尔德大气模型在我国各典型地区应用时比精确大气模型的误差大得多,尤其在离地高度0.5～7.0 km范围内最为明显,因此在我国对电波折射误差修正时最好不采用霍普菲尔德大气模型.Hopflied troposphere model and accurate troposphere model in radiowave refraction error modify in troposphere are gived. The conclusion is gived by simulate： error of Hopflied troposphere model is larger than accurate troposphere model in typical area in china, especially at height above ground from 0.5 km to 7.0 km. Therefore Hopflied troposphere model had better not be adopted for gain of accurate troposphere model.
