彗星的CCD成像观测

CCD Imaging Observation of Comets

近年来，对一系列彗星进行的宽带或窄带CCD测光得到了许多有趣的结果，为深入地理解彗星的物理性质、结构、起源和演化等提供了丰富的信息。文中简要地介绍利用CCD成像观测在测量彗核的自转、大小、形状、质量和研究彗核的活动以及彗发的形成和演化等方面的进展。

In recent years, many interesting results on comets have been obtained by use of wide bandor narrow band CCD photometry. These results provide a lot of information for understandingthe physical character, structure, origin and evolution of comets. In this paper, some researchresults on rotation, size, shape, mass and activities of nucleus of comets and comae obtained byCCD imaging observation are briefly reviewed.
