| 摘 要： | 1986年3月8日哈雷彗星发生一次Ⅰ型彗尾断尾事件,新主尾与老主尾的风差角不同。本文对我们所摄哈雷彗星大尺度底片,用光度测量方法定出主尾轴的视风差角;并且用导出的公式,算出相应的真风差角。最后,对所得结果进行一些讨论。

| Abstract: | A disconnection event (DE) occurred in the plasma tail of Halley's comet on March 8, 1986. The abrration angle of the new main tail differed from that of the old one. In this paper, the apparent aberration angles of the old and the new main tails on our large-scale plates were determined using a photometric method, and a transformation formula was derived. With the formula, the actual aberration angles of the old and the new tails on March 8 were found. Finally, the obtained results were discussed. |
