摘　　要：太阳发生耀斑时,辐射出大量的X线和高能粒子等,使得电离层的物质瞬间被大量电离,电离层的电子浓度急速变化,电离层的等效反射高度随之变化,从而引发甚低频信号相位异常现象。基于在河南新乡用甚低频接收机监测到的"神州"三号发射和返回期间的甚低频信号的相位异常情况,对相位异常的数据用最小二乘法进行了处理分析并给出了预测的耀斑级别,和美国的GOES卫星观测到的数据进行比较,结果吻合恰好,验证了此方法的可行性。When a solar flare, it radiates a lot of X-rays and high-energy particles, etc, and it makes large amounts of ionosphere substance ionized instantly, and, as the electron density of ionospheric change sharply, the equivalent reflection height of ionosphere changes too, thus causing the very low frequency signal＇s phase abnormal phenomenon. The phase abnormal situation of VLF signals is conducted, based the date from VLF receiver in Xinxinag, Henan province, during the launch and return of ＂Shenzhou III＂, and then, conducted the data handling analysis of the abnormal phase with the least square method and gives out predicted flare level, and compared the results between VLF receiver＇s monitoring with the American GOES satellite, and the two results match exactly, thus verifying the feasibility of the method.
