一、概述 物探时域激发极化法找矿仪器的发射机向地面相距几百至一千米的两点间送入一定功率的正—空—负相间的方波信号,如图2(b)所示,然后用接收机在供电两点中间的测线上以梯度法测量带有前后沿的方波信号的幅度,(即称为一次电位)和后沿曲线(即称为二次电位),如图2(a)所示,根据所测得的数据找出异常来判断有否埋藏金属矿床的可能性。

First, an overview geophysical time domain excitation polarization prospecting instrument transmitter to the ground a few hundred to one thousand meters between the two points into a certain power positive - empty - negative phase of the square wave signal, as shown in Figure 2 (b ), And then use the receiver to measure the amplitude of the square wave signal with front and rear edges (ie, referred to as the primary potential) and the trailing edge curve (ie, the secondary potential ), As shown in Figure 2 (a), according to the measured data to identify abnormalities to determine whether the possibility of buried metal deposits.
