| 摘 要： | 利用紫金山天台１３．７ｍ射电望远镜对２０个强ＩＲＡＳ远红外源（Ｆ１００μｍ〉５００Ｊｙ）进行了ＣＯ（１－０）的谱线观测，全部观测到ＣＯ发射，其中６个源为第１次观测到ＣＯ（１－０）谱线，在新观测的源中，５个可能有分子外向流，这些观测源的红外性质暗示出它们是仍深埋在分子云中的年轻星，显示出远红外源与分子云有关。

| Abstract: | The observations of CO(1- 0) line emission from 20 strong IRAS sources are made with the 13.7m telescope of Purple Mountain Observatory at Qinhai station. The result shows that all detected sources have CO emission. It includes first confirmed detection in CO for 6 far infrared sources, and 5 newly detected sources may have molecular outflows. According to the infrated properties of these sources , they are YSOs still deeply embeded in the clouds for which they formed, and far infrared sources are related with molecular clouds. |
