英文摘要: Using a newly installed system on the 25 m telescope of Urumqi Observatory, we searched for H2O maser emission towards 84 IRAS sources including young stellar objects (YSOs) and candidates for OH/IR stars. Water masers were detected in four star formation regions and one envelope of late type of stars for the first time. New water maser components were measured in two sources. In a maser source with no water maser emission detected six years ago, strong maser emission was found at different velocities, showing that there was a new explosion of water maser in this source.
