摘要
Through a comparison of AMT measurement between EH-4 and V8,the authors analyzed original data and inversion results of these two sets of devices in the same area,and made a comparative study of the performance parameters and work efficiencies of these two sets of devices.The results show that both V8 and EH-4 can collect real reliable data,V8 can collect lower frequency signal than EH-4,whereas EH-4 can collect higher high-quality frequency signal than V8.In addition,the continuity of data collected by V8 is better than that of data collected by EH-4,the efficiency of V8 is higher than that of EH-4,but EH-4 has the advantage of lower cost.
