| 摘 要： | 首次利用紫金山天文台青海观测站13.7m毫米波射电望远镜对若干分子云与恒星形成区的~(12)CO(J=1—0)和~(13)CO(J=1—0)分子辐射进行了观测,得到了各自中心位置的谱线轮廓。作为一个实例本文将介绍如何通过对分子云~(12)CO(J=1—0)和~(13)CO(J=1—0)谱线的综合分析与计算得到云中的物理参数。

| Abstract: | The 12CO(J=1-0)and 13CO(J=1-0)emissions in some star forming regions were observed with 13.7m millimeter wave telescope of Purple Mountain Observatory for the first time.In this paper,we present the spectra of center position for each source.The physical parameters of these sources are derived and the method to get the physical information of molecular clouds from J=1-0 lines of both 12CO and 13CO is also introduced. |
