摘　　要：针对钢板地电流测量装置校准系数求取较难的问题,充分利用修正傅里叶核函数平坦的频谱特性,根据长直导线与亥姆霍兹线圈校准系统的校准公式,得到两种情况下的校准系数,并利用该校准系数进行了钢板地电流的测量校准。所提出的钢板地电流测量装置校准系数的求取方法思路新颖,实现简单,具有较重要的工程应用价值。It is difficult to obtain the calibration coefficients of the steel plate ground current measurement apparatus. Based on the revised Fourier Kernel function （FKF）, this paper presents the use of flat frequency characteristics of FKF to obtain the calibration coefficients of a long straight wire and Helmholtz＇s coils calibration systems. Then, the measurements of steel ground current testing calibration are carried out which verify the effectiveness of the two sets of calibration coefficients. The approaches to decide the calibration coefficients are novel and simple, which can be extended to the performance testing of other systems.
