一次较大的太阳物质抛射的光学与射电研究

用H_α色球、射电运动频谱、射电日像和米波、分米波、厘米波段上的七个单频射电总流量的观测资料及地磁记录,对1982年1月22日太阳西边缘的物质抛射事件做了综合分析.用流量变化率曲线讨论了爆发特点.在绝热假设下推得抛射物质团在1.16R_⊙附近的内部磁场为12G,总电子数为1038,总能量为7×1029erg.事件的总抛射物质～1014-1015g,总能量～2×1030erg. 

An Optical and Radio Study of the Solar Limb Event of Jan. 22, 1982

The limb event with type III+V and type II bursts and H_α mass ejection of Jan. 22, 1982 is described in this paper. The characteristics of the associated radio burst in short decimeter and centimeter wave lengths is discussed using the curves of the flux density rate with time. The magnetic field strength in a main piece of the ejecta during the event (H ～12G), its mass (～1038 electrons, ～1014 grams) and energy in it (～60 erg/cm3, 8×1029 ergs) are estimated. An estimation of 1030 ergs for the total energy of this limb event is made.
