摘要：
1 Introduction Since the first OH maser source was detected in 1965, the astronomical masers have been used as powerful probes for the study of the early activities of stars and evolutions of stats. Among all the presently known maser sources, as it has a wide distribution and intense emission, and intimately associates with the early and late stages of stellar evolution, the OH maser has drawn a lot of attention and been
