文摘The features of the interstellar classⅡ methanol source reg io ns are grasped. A new pumping mechanism is argued. It can explain the formation of a series of J 0→J -1 E methanol masers and the increase of the maser intensity with J, while the 2 1→3 0A-+ methanol masers are regard ed as driving coherent microwave field.
