摘要
在非线性无力场的模型之下，我们设计出了一个估计太阳活动区水平电流的计算方法。解析解的检验表明，该方法是收敛的。
Within the framework of force free fields we developed a scheme for estimating the horizontal electric currents in solar active regions. The test shows that this method is well convergent. This method has avoided the divergence problems in previous extrapolation method.
