| 摘 要： | 本文利用VTEC(the Vertical Total Electron Contents)增量和VTEC变化率分析了电离层在2003年10月28日太阳耀斑期间中国的四个IGS跟踪站的响应情况.通过分析比较说明用VTEC变化率似更适合探测电离层对太阳耀斑的响应,并有望发现耀斑期间电离层的一些扰动现象,但在能得到高精度的绝对离层延迟的情况下,利用VTEC增量能准确全面地反映电离层对耀斑响应的整体变化情况. |

| Abstract: | This paper has adopted two variables,called the enhancement and the change rate of VTEC,to study the ionospheric response to the solar flare on 28 October 2003 with data from four IGS track stations in China.Research results indicated that the change rate of VTEC seems to be relatively more available for detecting the ionospheric response to the solar flare,and meanwhile,it is possible to discover the ionospheric disturbance during the solar flare.It should also be pointed out that the enhancement of VTEC can accurately reflect in detail the true situation of ionospheric response to the solar flare if one can obtain high-accuracy absolute ionospheric delay. |
| Keywords: | solar flare ionosphere VTEC enhancement VTEC change rate |
