本文利用1977～1993年天龙座流星雨的17年资料和中日两国同时期北京，国分寺等8个电离层站Es层观测结果，研究了八十年代天龙座强流星雨爆发期间，中日两国垂测站网fbEs参数的反常变化情况，不仅与其母彗星（CometP／Giacobini-Zinner）的回归，同期目视，光学及摄像流星观测和六十年代狮子应强流星雨的爆发作了比较，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。 Based on the 17-year meteor shower data of the Draco from 1977 to 1993 and the Es layer observations of 8 ionospheric stations in Beijing and Guodisi during the same period of China and Japan, The abnormal variation of the fbEs parameters of the vertical network not only compares with the regression of its Comet / Giacobini-Zinner but also with the simultaneous visual, meteorological and meteorological observations during the same period and the explosion of the meteors of the meteor shower in the 1960s, The meteorological maintenance mechanism of the Es layer of f, l and c in the mid-latitude region was preliminarily discussed.
