Physico-Chemistry of Comets: Models and Laboratory Experiments
      
This paper is a review dealing with the organic chemistry of comets.
      


Comet is a peculiar object in the solar system. Under the action of solar radiation and the solar wind, comet experiences various physical and chemical processes, resulting in the variations of the appearances (coma, tails), brightness, spectrum and kinetic character of the comet. The study on comets is an important subject in astronomy and space science, which is of significance in studying the origin of the solar system, the origin of the organic molecule and even life, the solar wind and plasma processes.Famous...

Comet is a peculiar object in the solar system. Under the action of solar radiation and the solar wind, comet experiences various physical and chemical processes, resulting in the variations of the appearances (coma, tails), brightness, spectrum and kinetic character of the comet. The study on comets is an important subject in astronomy and space science, which is of significance in studying the origin of the solar system, the origin of the organic molecule and even life, the solar wind and plasma processes.Famous Hally Comet will return to inner solar system in 1985-'1986. Varied cometary phenomena are to be observed. The sample analysis and the various observations from both groundbases and redevous spacecrafts will help advance the study of comet to a new stage. In this paper, the plan of the International Halley-Watch (IHW) is introduced briefly. Then, some progresses in the study of comets are reveiwed, including (1) chemical composition and chemical processes of comets; (2) dust tails and grains; (3) plasma tails; (4) coma; (5) cometary brightness, outburst and splitr ting; (6) vaporization, lifetime of the cometary nucleus and the non-gravitational effects; (7) the cometary nucleus, in which some studies of comets in a China are also mentioned.

彗星是太阳系的一种奇特天体。在太阳辐射和太阳风作用下,彗星发生一系列物理过程和化学过程,表现为外貌形态(彗发、彗尾)、亮度、光谱及运动特性等多种变化。彗星研究是天文学和空间科学的重要课题,对于了解太阳系起源、有机分子仍至生命起源、太阳风及等离子体过程都有重要意义。 著名的哈雷彗星将在1985—86年再次回归到内太阳系。它有多种彗星现象,从地面到近地空间及空间会合的各种观测及样品分析,预料会取得彗星研究的新进展。本文先概述国际哈雷彗星联测(IHW)的计划;然后,评述彗星研究的一些进展,包括:(1)彗星的化学组成和化学过程;(2)尘埃彗尾和颗粒;(3)等离子体彗尾;(4)彗发;(5)彗星的亮度、爆发和分裂;(6)彗核的蒸发、寿命及非引力效应;(7)彗核,其中也包括我国的彗星研究情况。
