摘要
传统电阻率法仪器属单通道仪器,为适应梯度电阻率测深剖面的观测,研制了多通道电阻勘探仪.它的各个观测通道均有极化补偿电路,一次供电就可以连续测量多道电位差与电流强度的比值数据,极大提高了野外实测工效,并且适宜梯度电阻率测深剖面的观测.该仪器在采空区上实施三极梯度测深剖面,取得了成效.
Traditional resistivity instruments are single-channel instruments. Muhi-channel resistivity instruments are developed to adapt to gradient electrical sounding. Each channel of the new instruments has a polarization compensation circuit. Single battery charge can measure continuously the ratio of muti-channel potential differente to current intensity. Thus, the efficiency of field work can be raised greatly. This is also very suitable for gradient electrical sounding. The new instruments have been applied successfully in triple-pole gradient sounding for worked-out section.
