六十年代狮子座强流星雨爆发期间的E_s层

The Es Layer during the Burst of the Strong Leonid Meteor Shower in the Sixties

利用1960年～1993年狮子座流星雨的34年资料和我国同时期Es层观测结果，研究了六十年代狮子座流星雨爆发期间，我国垂测站网fbEs参数的重大变化情况，不仅与其母彗星（CometP／Temple－Tuttle）的回归和同期目视及金达流星观测作了比较，而且还对中纬区f、l和c型Es层的流星维持机制作了初步讨论。

In this paper, anomalous variations of fbEs parameters at 7 chinese ionospheric stations are studied by using the 34 simultaneous observational data of the Leonid meteor shower and the Eslayer from 1960-1993 during the burst of the strong Leonid meteor shower in the sixties. These ionospheric stations consist of the following 7 stations: Lanzhou (36. 07°N, 103. 87°E); Chongqing (29. 50°N, 1106. 42°E); Beijing(40.00°N, 116. 30°E); Changchun (43. 83°N, 125. 27°E); Manzhouli (49. 58°N, 117. 45°E); Guangzhou (23. 15°N.113. 35°E) and Hainan(20. 00°N, 110. 33°E). Not on ly comparing the results with the return of Comet Temple-Tuttle, parent comet of the Leonid meteor shower, and simultaneous observational data of visual meteors and radio meteors, but the comet keeping mechanism of the sporadic Es-f .Es-l and Es-c layers at midlatitud are also discussed briefly in this paper.
