摘　　要：本文介绍了在1986年2月6日21时12分开始的急始型强磁暴主相期间,我国乌鲁木齐、兰州、北京、长春、满洲里、重庆和海南站观测到微粒E层的情况,结合同时的地磁、宇宙线和TEC的观测结果,电离层的各种变化和日本国分寺等5个地面垂测站的月报表,对1986年2月7日和8日午夜前后在远东地区出现微粒E层事件的概貌和特征作了初步概括和讨论。作者认为,粒子沉降可能是形成此次微粒E层事件的主要原因。In this paper, data of the particle E received at Wulumuqi, Lanzhou, Beijing, Changchun, Manzhouli, Chongqing, Hainan, Kokubunji, Akita and Yamagawa and the simultaneously observed data of ionosphere, geomagnetism, cosmic rays and TEC are used, to discuss a general picture and character of the event of the particle E during the main phase of the great magnetic storm of sudden commencement only at night on February 7-8, 1986 in the Far East. It is supposed that the particle precipitation may have been the main cause for this event of the particle E and its maximum occurrence is located above 30 degrees of the geomagnetic latitude.
