导电水泥电阻的交直流电测试方法研究

Study on AC and DC Measuring Method of Electrical Cement Resistance

采用交、直流电对不同膨胀石墨含量的导电水泥电阻进行测量，根据试验数据对比，分析了交、直流电对电阻测量的影响，同时，研究了不同的交流电压对测量导电水泥电阻的影响，为导电水泥电阻的工程化测量奠定了基础。

The electrical cement resistance is measured by the alternating current （AC） and direct current （DC） in this paper. Through the contrast of experiment data, the influence of the AC and DC for measuring resistance is analysed. The influence of different size AC for measuring resistance is also studied. This paper establishes the foundation for measuring electrical cement resistance.
