电阻率法目前在水文工程地质、煤田以及固体矿产物探方法中仍是一种主要方法,绝大部分可使用的仪器仍是DDC-2电子自动补偿仪。该仪器是我国在64年仿制苏联50年代的仪器,仪器笨重、观测精度低、功能差是人所共知的。为了改变我国仪器落后面貌,推广激电找水,北京地质仪器厂在地 Resistivity method is still a major method in hydrological engineering geology, coalfields and solid mineral geophysical exploration methods, most of the instruments that can be used are still DDC-2 electronic automatic compensator. The instrument is the imitation of the Soviet Union in the fifties of 64 in the instrument, bulky instruments, low accuracy, poor function is well known. In order to change the backwardness of our instruments, to promote the electricity to find water, Beijing Geological Instrument Factory to the ground
