摘要
本文对Ｏｓｈｅｒｏｖｉｃｈ的黑子返回磁通量模型作了适当的修改，使用黑子中心作为边界条件，用五种观测结果，导出了理论模型所需的五个主要参量，用半经验方法求得了黑子静力学模型的磁场、压力和温度等物理量．将此模型应用于一个中等大小的圆形对称黑子，可得到一个特解，结果发现我们的模型既能满足黑子的磁性质，同时又能满足合理的热力学量分布．
with few modifications on the Osherovich's return-flux model of sunspots, a set of solutions are obtained and the needed parameters are determined by checking observation. All physical quantities at sunspots center are used as the main boundary condition, which is different with the traditional choice at the infinite or at the non-perturbed photosphere. A particular solution is obtined by this model for a medium sized, cylinderically symmetrical unipolar sunspot. It is found that the present results are in good agreement with both magnetic features and thermodynamic quantities.
