摘　　要：GeoERT IP 2401四维遥测多功能高密度极化率仪,采用一套金属电极就可以同时测量高密度极化率和高密度电阻率,解决了金属电极的极化问题,拓宽了高密度电法在矿产地质、水文地质、环境地质、工程地质方面的应用。利用滤波、叠加和相关检测技术提高抗干扰能力;仪器输出功率大,自动调节供电电压,大大提高了勘探深度。多道技术可以做三维高密度电法勘探,采用遥控技术可以进行时移四维高密度电法勘探,追踪地质异常的变化规律。The GeoERT IP 2401 four-dimensional telemetry multi-function high-density polarizability instrument developed by our team can simultaneously measure high-density polarizability and high-density resistivity with only one set of metal electrodes.This solves the polarization problem of metal electrodes and broadens the application of high-density electrical method in mineral geology,hydrogeology,environmental geology and engineering geology.The anti-interference ability is improved by using filter-ing,superposition and related detection technologies;the output power of the instrument is strong,and the power supply current is automatically adjusted,which greatly improves the exploration depth.Multi-channel technology can be used for three-dimensional high-density electrical exploration,and remote control technology can be used for time-shifted four-dimensional high-density electrical exploration to track the changing patterns of geological anomalies.
