煤介电常数测量方法研究是准确获取煤炭介电特性的重要前提,也是进行煤炭电介质物理学理论和应用探索的重要途径。针对煤炭介电常数对地球物理勘探、矿井地质灾害预警、煤炭脱硫和电力炼焦研究领域的重要作用,基于国内外系统的文献调研,系统分析和总结了国内外关于煤介电理论模型和介电常数的测试系统和测量方法的研究进展。最后,指出了目前煤炭介电常数测量方法的不足,为今后研究及发展趋势提出了建议和意见。

A research on the measuring method of the cal dielectric constant would be an important prerequisie to accurately have the coaldielectic features andwould be an important ac.ss to the dielectric physics theory and appication discoveryof the coal. According to the important role of th coaldielecric constant to thgeophyscal xploraton,the early warning of the mine geologic disasterthe coal desufuization and the research reaof the electic power and coking.based on the documentary investigation on the domesticand overseas systems the paper had a systematic analysis and sunmaization on the research progress on the domestic and overseas coal dielecric theoretical model and the measuring system and measuing method of the diletric constant.Fnaly the paper pointed out tht the present measuring methods of the cal dielectic constant were insuficient. The paper provided the proposals and comments on the late research and development tendency
