| 摘 要： | 本文总结了发生在中国境内的十次日食电离层效应的观测结果和理论解释,是已发表的讨论日食地磁效应的姊妹篇。从1936年6月19日到1981年7月31日的十次日食跨越了近半个世纪。本文讨论了下述问题:（1）各次日食的f0E、f0F1、f0F2的变化;（2）电离层温度变化与暂态现象;（3）日食与E及扩展F层;（4）日食电离层效应与地磁日食效应的比较;（5）对今后开展日食工作的意见。本文主要论述我国学者的九次电离层效应的观测结果,不包括由于抗日战争中断的1941年9月21日的日食电离层效应的观测结果。

| Abstract: | In this paper observational and theoretical interpretation of ionospheric effects during the previous 10 solar eclipses occurring in China are summarized. These 10 eclipses began on 19 June 1936 occurring over the course of nearly half a century until 31 July 1981. This is a companion paper to an earlier article dealing with the geomagnetic effects of solar eclipses already published by us in the Planet.Space Sci. 30, 587-594, 1982.In this paper the following problems are dicussed: （1） variations of f0E, f0F1, f0F2 during each eclipse; （2） ionospheric temperature and transient changes; （3） solar eclipse and Es and spread F; and （4） comparison with geomagnetic observations and favourable conditions to discover the optical eclipse-effects. It should be emphasized that this paper mainly deals with Chinese contributions to the observations of ionospheric effects for all 9 cases, excluding the case of Sept. 21, 1941, which was interrupted due to the unfortunate Sino-Japanese war at that time. |
