摘　　要：使用G856和GSM-19T质子磁力仪在同一个测区进行磁测数据采集,由于这两种型号的质子磁力仪观测数据文件格式不一样,用其配套软件相互日变改正特别困难和繁琐,并且用其配套软件日变改正没有五点或七点滑动平均。为了解决这些问题,在Microsoft Office Excel平台编写五点或七点滑动平均和日变改正VBA程序。该程序经实验验证和一个测区20971个磁测数据生产应用验证表明VBA程序的正确性。这个VBA程序适用不同型号的质子磁力仪观测数据之间日变改正,只要把观测数据转换到Microsoft Office Excel中并插入VBA程序代码即可进行日变改正,非常实用、快捷。When using G856 proton magnetometer and GSM-19T proton magnetometer to collect magnetic data in the same area, the mutual diurnal correction is particularly difficult and complicated with its supporting software, and its supporting software diurnal correction does not get five-point or seven-point moving average, cause these two types of proton magnetometer data file format is different. In order to solve these problems, the paper writes the five-point or seven-point moving average and the diurnal variation of VBA program in Microsoft Office Excellplatform. The program is verified by experiment and a survey area 20971 applied magnetic data proved the correctness of VBA programs. The VBA program for proton magnetometer data can be applied in different types of correction for diurnal variation, it just need to convert the data into Microsoft Office Excelland insert the VBA program code to do diurnal correction, it＇s very practical and fast.
