摘　　要：We present a multi-line study of the massive star-forming region IRAS 22506＋5944. A new 6.7 GHz methanol maser was detected. ^12CO, 13CO, C180 and HCO＋ J = 1 - 0 transition observations reveal a star-formation complex consisting mainly of two cores. The dominant core has a mass of more than 200 Mo, while the other one is only about 35 340. Both cores are obviously at different evolutionary stages. A 12CO energetic bipolar outflow was detected with an outflow mass of about 15 Mo.We present a multi-line study of the massive star-forming region IRAS 22506＋5944.
