A theoretical model of a cold and dense isolated solar prominence is presented. The thermodynamic parameters of a filament (gas pressure, density and temperature) are calculated from a specified magnetic field structure. The filament lies above the photospheric polarization separation line and its magnetic field falls off rapidly with distance from the axis, so that the total electric current along the axis of the filament equals zero. The prominence has a helical magnetic field structure divided into separate thin filaments. The density and temperature distributions of the prominence derived from the equilibrium conditions for this kind of magnetic field correspond well to the known observed parameters.

静止日珥的细丝结构

提出了一个寒冷而密集的孤立日珥的理论模型。灯丝的热力学参数（气体压力、密度和温度）是根据指定的磁场结构计算得出的。灯丝位于光球偏振分离线上方，其磁场随着离轴的距离迅速衰减，因此沿灯丝轴的总电流为零。突起具有螺旋磁场结构，分为单独的细丝。从这种磁场的平衡条件导出的日珥的密度和温度分布与已知的观测参数很好地对应。
