| 摘 要： | Ｋｉｐｐｅｎｈａｈｎ－Ｓｃｈｌｕｔｅｒ模型回路和Ｋｕｐｐｅｒｕｓ－Ｒａａｄｕ模型回路是暗条电流回路的两种极端形式，本文则从一般回路形式来研究暗条电流与暗条高度的关系。结果发现：当暗条电流与活动区磁场作用的Ｌｏｒｅｎｔｚ力方向与暗条重力方向相同时，流入活动区光球层的电流越大，其在暗条电流中所占的比例越大，暗条越稳定。当二力方向相反时，流入活动区光球层的电流越大，其在暗条电流中所占的比例越大，暗条越不稳定。

| Abstract: | Among the various filament current circuits,the Kip penhahn-Schluter Model curret circuit and the Kuperus-Raadu Model current circuit are extreme cases.In this paper,relations between the filament current and the balance altitude are investigated within a general current circuit.The main results obtained are:(1)when the direction of the Lorentz Force interacting between the filament current and the magnetic field in an active region is same asthe direction of the filament gravity,the larger the current flowing from the filament to the photosphere layer is,the larger the rate in the filament current is,and the stable the filament is.(2)when the two directions are adversed from each other,the larger the currentflowing from the filament to the photosphere layer is,the larger the rate is,and the instabler the filament is. |
