| 摘 要： | 通过分析前人对耀斑期间电离层各区域电子密度的变化情况，总结了一个应用耀斑期间的高频多普勒扰动记录估算出层总电子含量变化的方法，并应用这一方法计算了１９９０年３－６月几次耀斑引起的低电离层总电子含量的变化，同时还与各耀斑对应的最大流量密度进行了比较，并对两者之间的相关情况进行了分析。

| Abstract: | By analyzing the change of electron density in different ionospheric regionsduring flare bursts, a new method is introduced, by which the TEC enhancement inthe lower ionosphere during the initial phase of a flare burst can be calculated usingHF Doppler records. Some TEC enhancements caused by flare bursts from Marchto June in 1990 are calculated using this method. The results of TEC enhancementare compared with the maximum fluxes of the soft X--ray of the corresponding flares.The correlation between the calculated TEC enhancement and maximum fluxes ofthe soft X-ray radiation of solar flares are fairly good in general, except very intenseflares. |
