一般电阻法的视电阻率测量都是使用电位计进行工作,在操作中还是分别两次来读电位差与电流强度的。这就需要繁复的变换测量线路,因而使工作效率降低。为了提高工作效率建议使用视电阻率测量的一次读数方法。这一方法主要是将毫安计串联于电位计的供电线路中,由操作员观测电位计读电位差,由记录 The general resistance method of the apparent resistivity measurement is to use the potentiometer to work in operation or respectively, to read the potential difference and the current strength. This requires complex conversion measurement lines, thus reducing the work efficiency. In order to improve work efficiency, it is recommended to use one reading method of apparent resistivity measurement. This method is mainly the milliammeter in series with the potentiometer power supply line, the potentiometer by the operator to read the potential difference from the record
