摘　　要：以安徽庐江台观测资料为基础,分析数字化测氡与人工取样测氡结果的精度、相关性、影响因素等。数字化测氡观测精度高,但受气温、气压影响较大;气氡与水氡资料动态特征有较大差异,数字化气氡值与人工测气氡、人工测水氡不相关,水气Rn/Rn与井水温成正比。由于数字化测氡观测时间较短,资料又非常有限,还缺少一定的震例,因此,在一定时间内数字化测氡与人工测水氡应同时进行。Based on the artifical and digital observation data of Radon in Lucian station, we have analyzed precision, relativity and influencing factors of the observation results. Digital observation data have higher precisiom and influence of the temperature and atmosphere. The change characteristics of gaseous Radon is different to that of water Radon. The observation valus of the digital gaseous Radon isn抰 correlated with the values of the artificial gaseous and water Radon. The ratio of Radon(gas) to Radon (water) is directly proportional to the water temperature. Consequently, the digital observation and artificial ovbservation should go togher for a long time.
