中文摘要：

用 Urumqi 天文台的 25 m 望远镜上的一个最新安装的系统，我们包括年轻星的目标(YSO ) 和 OH/IR 星的候选人向 84 IRAS 来源寻找了 H_2O 微波激射排放。水微波激射在区域和一个信封近来第一次星打的四星形成被检测。新水微波激射部件在二来源被测量。在没有六年以前检测的水微波激射排放的微波激射来源，强壮的微波激射排放在不同速度被发现，证明有在这来源的水微波激射的新爆炸。

英文摘要：

Using a newly installed system on the 25 m telescope of Urumqi Observatory, we searched for H20 maser emission towards 84 IRAS sources including young stellar objects （YSOs） and candidates for OFUIR 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.
