Summarizing the results above, we further obtained: Hα blue asymmetry observed usually in the early stage of flares may be caused by chromospheric condensation in transition region; the Hα red asymmetry appeared later may be resulted from the downward movement of upper chromosphere; and still later CaIIK asymmetry may be explained to have 10-20 km/s downward velocity in middle or lower part of chromosphere, This explanation is self-consistent among the observations of Hα and CaIIK line during the flare.

综合所有计算的不对称特征，我们进一步得到：耀斑早期的短时间兰不对称性可由过渡区里的色球凝聚引起，随后的红不对称性是色球上部物质向下运动的结果，而后来出现的CaⅡK不对称特征则表明色球中下部具有10-20km/s的向下运动速度。

In order to solve the problems of bad shunting and red light strip phenomenon at electric railway section caused by the defective of asymmetric pulse track circuit receiver formerly, a new type of asymmetric impulse track circuit receiver is designed. It takes the PIC16F887 single-chip microcomputer as central processing unit of the system, realizes processing and judging the asymmetric impulse from the track transformer automatically. The article focused on the receiver work flow, hardware circuit and software design.

摘 要：为了解决以往多数不对称脉冲轨道电路接收器存在缺陷而导致的分路不良问题和电气化区段空闲&红光带&现象，设计了一种新型脉冲轨道电路接收器，系统以PIC16F887单片机为核心处理单元，自动实现对由轨道变压器传来的不对称脉冲信号进行处理和判决，重点讨论了接收器工作流程、硬件电路实现以及软件设计。
