采用级数解解析地表征出了横向谐变磁场下矩形薄板的涡电流密度，同时给出了小波伽辽金解法.其数值结果与变分法比较后不难发现：本文的这两种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，为工程中的涡电流计算提供了两种简单而又有效的方法.

A series solution is adopted to express the eddy current density of rectangular lamina under transverse sinusoidal magnetic field, and the wavelet-Galerkin method is also given for the same problem. Compared with variational method, the numerical results indicate that the two methods not only have computational precision improved, but also reduce the computational memory and time largely. Two simple and effective solutions are provided for the calculation of eddy current in the project.
