摘要
通过EH-4连续电导率仪及V8多功能电法仪的音频大地电磁测量对比实验,详细分析了两套仪器所采集的原始数据及反演结果,并从仪器性能指标及工作效率等方面对两套仪器进行了对比研究。研究表明两套仪器都能采集到真实可信的数据。V8多功能电法仪能获得更低频段的信号,EH-4连续电导率仪则能采集到较高质量的高频信号。相比较而言,V8多功能电法仪所获得数据的连续性要好于EH-4连续电导率仪,且其工作效率要高于EH-4连续电导率仪,但就工作成本而言,EH-4连续电导率仪有更大优势。
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.
