摘要收集了最新的河外水脉泽样本资料(截至2007.03),并计算给出这些源的部分物理参数.主要分析了水脉泽辐射和脉泽寄主星系的红外辐射之间的可能相关性.分析结果显示河外水脉泽源与银河系内脉泽源一样,水脉泽辐射光度和脉泽寄主星系的红外辐射光度存在相关性,即LH2O^10-9LFIR. In this paper, the newest sample （to March,2007） of extragalactic H20 maser sources is compiled and some of their physical parameters are collected and derived. The relation is mainly investigated between H20 maser emission and infrared emission of maser host galaxies. The results show that the correlation exists in extragalactic masers sources, i.e. LH2O-10^-9LFIR., similar to the case in the galactic sources
