摘要
导出了非线性静磁平衡方程的一个幂级数形式的相似解,和使这一级数收敛的解的参数范围。阐明了在此范围内的一组参数对应于一个平衡位形和在这个范围之外的一组参数不对应于一个平衡位形(非平衡)。并绘出了一个非线性的平衡位形。 结果可用于解释:多带耀斑的产生、双拱磁结构和拉长的复杂黑子群上空的磁场结构。
A similarity solution to the nonlinear magnetostatic equilibrium equation (6) is derived, which has the form of power series. A region of the parameters of the solution in which the series may be convergent is derived. It is stated that a set of the parameters in the region corresponds to a nonlinear magnetostatic equilibrium configuration and that out of the region does not correspond to an equilibrium one (nonequilibrium). A configuration of nonlinear magnetostatic equilibrium is plotted in Fig. 1.The results are used to interpret the producing of multiple-ribbon flares, two-arch magnetic structures and the structures of the magnetic field above the elongated complicated groups of sunspot.
