德意志联邦共和国于1976年到1978年在用激发极化法勘探矿产时,总共记录了6282条IP衰减曲线的形状.为节省时间,进行时间域测量时,在每一测点只观测曲线的三个时间区间积分段(或充电率).这三段区间的时限分别是:130～650.650～1170和1170～1690毫秒(图1).直流脉冲持续时间和断电时间均为2秒.仅对偶极-偶极排列的测量结果做了统计.偶极长度为30～60米,两偶极的间距是偶极长度的2～8倍(n=2～8).
In the period from 1976 to 1978, the Federal Republic of Germany surveyed the shape of the 6282 IP decay curves when it was used to excite the mineralization by exploratory polarization. To save time, only time-domain measurements were observed at each measuring point for three (Or charge rate) of the time interval.The time intervals of the three sections are: 130 ~ 650.650 ~ 1170 and 1170 ~ 1690 ms (Figure 1). The duration of the DC pulse and the power-off time are both 2 seconds. The results of the measurement of the dipole-dipole array have been calculated. The dipole length is 30 to 60 meters and the distance between the two dipoles is 2 to 8 times the dipole length (n = 2 to 8).
