摘　　要：G8 5 6 ZD质子旋进磁分量仪是在原G85 6质子旋进磁力仪的基础上再开发而成的。该仪器采用双CPU工作方式 ,并且保留了G85 6质子旋进磁力仪的原有功能。其基本原理是用补偿法测量磁分量。将探头放在一组正交Helmholtz线圈内 ,同时加上补偿电流 ,使探头所在的空间得到均匀的补偿磁场 。The proton vector magnetometer G856 ZD is re developed on the basis of the former proton precession magnetometer G856. The instrument applies double CPU working model and retains all existing functions of the magnetometer Model G856. The basic principle of the instrument is to measure the total magnetic field vector and magnetic declination angle by the compensation (Nelson) method. The measuring steps are:first, the sensor is installed in the center of the Helmholtz coils, then the compensation current is added, so that a uniform compensation magnetic field is obtained in the space where the sensor is placed, and the continue automatic measuring of magnetic vector and declination is realized.
