解释电法勘探资料常用形状规则的模型靶进行物理模拟实验.靶往往都是用电子导电金属材料制作或将细粒导电材料与不导电的材料混合,经树脂或水泥胶结而成. 实验一般采用四极装置进行测量,用交流电供给.常使用一个固定频率(1000赫左右),有时也用低到50或60赫,甚至更低的频率.由于靶与电解质界面间的阻抗随频率改变,所以测得的视 Explain the commonly used shape rule model targets in electrical prospecting data to conduct physical simulation experiments, the targets tend to be made of electron conductive metal materials or mixed with fine conductive materials and non-conductive materials and cemented by resin or cement. Quadrupole devices measure with alternating current and often use a fixed frequency (around 1000 Hz), sometimes as low as 50 or 60 Hz, or even lower. Since the impedance between the target and the electrolyte interface changes with frequency, Measured visual
