| 摘 要： | 用紫金山天文台青海观测站１３７ｍ射电望远镜对Ｓ１４６和ＩＲＡＳ２３５４５＋６５０８进行了１２ＣＯ（Ｊ＝１－０）谱线的成图观测，结果表明两源附近存在ＣＯ高速外向流．分析了这两个外向流的形态，求出了其物理和动力学参数，同时结合ＩＲＡＳ资料，对中心源的演化阶段和环境气体的热特性作了分析．

| Abstract: | A 12 CO( J =1-0)line-mapping observation using the newly built 3mm system of the 13 7m radio telescope at the Qinghai Station of Purple Mountain Observatory showed there are high velocity molecular outflows near IRAS 22475 5939(S 146)and 23545 6508.The morphologies of the two outflows are analyzed and their physical and dynamical parameters are calculated and discussed.Using the IRAS data,the evolutionary status of the central sources and the thermal characteristics of the ambient gas are also investigated. |
