在安徽省两个已知磁铁矿区上进行了可控源音频大地电磁法（ CSAMT）张量测量与标量测量的对比试验，根据已知地质勘探剖面进行了应用效果的对比工作。试验结果表明，在一维层状电性结构条件下，张量测量与标量测量的找矿效果相近；在电性结构复杂情况下，张量测量的找矿效果优于标量测量结果。同时，指出可CSAMT法张量测量工作需进一步探讨和亟待研究的一些问题。
在安徽省兩箇已知磁鐵礦區上進行瞭可控源音頻大地電磁法（ CSAMT）張量測量與標量測量的對比試驗，根據已知地質勘探剖麵進行瞭應用效果的對比工作。試驗結果錶明，在一維層狀電性結構條件下，張量測量與標量測量的找礦效果相近；在電性結構複雜情況下，張量測量的找礦效果優于標量測量結果。同時，指齣可CSAMT法張量測量工作需進一步探討和亟待研究的一些問題。

Tensor measurement and scalar measurement of the CSAMT method were conducted in two known iron ore districts of Anhui Province, and a comparison of the application results was made along the known geological exploration section. The results of the test show that, under the condition of 1?D layered electrical property structure, the ore?prospecting result of the tensor measurement is close to that of the scalar measurement, whereas under the condition of complex electrical property structure, the ore?prospecting result of the tensor measurement is better than that of the scalar measurement. Some problems which require further investigation in the tensor meas?urement of the CSAMT method are also discussed in this paper.
