摘　　要：介绍了NMF、VMF1和GMF的干湿分量投影函数的基本数学模型和计算方法,比较了其间的差异和对应的静态PPP结果,得出了相关的结论。We introduced basic mathematical model and calculation method for hydrostatic and wet mapping functions of NMF.VMF1 and GMF, and compard the three different mapping functions. Based on the precision precise point positioning softvvare. TriP, serval IGS tracking station on different latitude area were choosed to static precision point position, using the three mapping functions respectively.
