| 摘 要： | 本文采用圆柱坐标并假定总压力(气压和磁压之和)只与高度有关, 求得了三维两分量磁静平衡方程的通解.通过调节这一通解中出现的两个任意函数可得到各种特解.在应用这种特解去解释有关太阳物理现象时将不受小扰动条件的限制.同时, 我们找到一组特解, 可定性解释黑子内部的纤维结构和黑子外形的非轴对称性.

| Abstract: | The present paper describes a general solution to the three-dimensional, two-con-ponent magnetostaitic equations in cylindrical coordinates, assuming the total pressure (sum of gas pressure and magnetic pressure) is a function of the altitude only. By adjusting the two arbitrary functions appearing in the general solution one may produce various patieular solutions which are not subjected to any limitation of perturbation conditions while applied to solar phenomena. Moreover, it is found that a particular solution as to qualitatively elucidate the asymmetry of sunspots in shape in addition to the filamentary structure in sunspots. |
