摘　　要：选取2015-2019年洱源水化站FD-105K与FD-125测氡仪对比观测资料,采用一阶差分、F检验、t检验等方法进行对比分析,结果显示:FD-125测氡仪测值总体偏低,且测量精度较低,数据离散程度较高;2套观测数据变化趋势一致性不理想,相关性较低,未通过F检验和t检验。综合分析认为,FD-125测氡仪暂时不能替代FD-105K测氡仪进行观测,需要增加震例对2套仪器的映震效能进行验证。The comparative observation data of FD-105 K and FD-125 radon meters at Eryuan Hydrochemical Station from 2015 to 2019 were selected and analyzed by first-order difference, F-test, and t-test. The results show that the values of FD-125 are generally smaller than that of FD-105 K radon meter, and the data stability is poorer and more discrete. The trend consistency of the two sets of observations was not ideal and their correlation was low, which did not pass F-test and t-test. Comprehensive analysis shows that FD-125 radon meter cannot replace FD-105 K radon meter for observation at present, and earthquake cases are needed to check the reflecting efficiency of the two sets of instruments.
