摘　　要：根据对下关温泉１９９２年８个水化观测项目主成分进行的分析及影响因素的研究，发现氡和气压、水温和ＰＨ值、氩和氮、二氧化碳分别构成独立性较强的４个主成分．In this paper,main compositions of 8 hydrochemical ovservation items in Xiaguan hot spring in 1992 have been analysed and the disturbance factors have also been studied.The results show that radon and air pressure,water temperature and PH values,argon and nitrogen,and CO 2 are 4 main compositions which have stronger independence.Air pressure and flow quantity are the main disturbance factors to the chemical compositions.
