摘　　要：对于横向谐变磁场下的矩形薄板涡电流问题 ,给出了能够解析地表征出涡电流密度的级数解 ,并与变分法加以比较。结果表明 :该方法不但数值计算精度高 ,而且使计算存贮和计算时间大量降低 ,为工程中的矩形薄板涡电流计算提供了一种简单而又有效的方法。A series solution of eddy current expressed by analytical method is given for eddy current problems of rectangular lamina under the transverse magnetic field which varies with harmony. As compared with the variational method, the results indicate that the method in this paper not only improves the numerically computational precision, but reduces the computational memory and time. The simple and effective method is provided for the calculation of eddy current in the project.
