Starting with the research on the characteristics of frequency spectra of the ip field as well as charging - discharging time and based on experiment results , the authors summed up frequency spectra , time spectra and decay rate characteristics of sulfide mineralized bodies ( chalcopyrite ) and graphite - bearing dolomitic marble , and detected new parameters for qualitative evaluation of ip anomalies 摘要从研究激电场频谱特征及充、放电时间特征出发,根据实验观测结果,总结了硫化物矿化体(黄铜矿)及含石墨白云质大理岩等岩性的频谱特征及充放电时间特征,探索到新的定性评价激电异常源参数频率谱及时间谱、视衰减速度。
