摘　　要：利用恒电流法对水泥基材料的电性质进行测试,按照电介质模型和电解质模型对实验数据进行处理,所得到的电参量可以较好地表征水泥基材料的性质.在电解质模型中,将响应方程进行数学处理可以求得等效电路参数.与时间电流法的结果相比,利用恒电流法所得到的对照结果都能得到很好的解释.Galvanostatic method,one of the transient techniques of electrochemistry in common use,has been introduced to measure the electric characteristics of cement-based material.Two different models i.e.dielectric and electrolytic models were proposed for calculation and explication.The results from electrolytic model is in good agreement with that obtained from chronoamperometry.
