【摘要】 本文评论了约有十年历史的银河CO巡视在分子云寿命,分子云和银河结构,分子云的物理性质,分子云在银河的分布等几个方面所取得的进展和结果。特别突出地介绍了各方面目前尚存在的分岐意见。最后,从CO巡视本身,结合这几方面存在的问题,论述了银河的CO巡视工作不是已接近尾声,而是有待深入地发展以趋完备。更多还原

【Abstract】 A review about the progress and results in respects of the molecular clouds and galactic structure, the lifetime, the physical properties and the distribution in our Galaxy of interstellar molecular clouds from galactic CO surveys during the last decade is given in this paper. Especially, different points of view existed in this field for the moment are prominently presented. In the last part, so far as the CO survey itself and the problems are concerned, the author concludes that CO survey has not yet come to an end, and it remains to be developed in depth.更多还原
