在相同观测条件下，对比分析洛阳地震台观测井FD-105K型与SD-3B型模拟水氡仪同期观测资料，结果显示，实际观测变化趋势一致，数据动态变化类似。一阶差分分析表明，FD-105K仪观测数据整体波动性较SD-3B仪小，且观测质量较优；一致性检验（相关系数分析、F检验、t检验）结果表明，FD-105K和SD-3B仪观测数据相关性良好、变化趋势一致，但方差和均值变化不一致。
Under the same observation conditions, geophysical characteristics of water radon, the radon-measuring equipment together with measurement methods and principles were used to analyze the corresponding monitored data of FD-105K and SD-3B in the paper. Results of primary comparative analysis showed that FD-105K shared similar dynamic change with SD-3B proving that the two instruments exhibited good coherence in observation significance. Data of the first difference comparative analysis showed that the variation tendency of FD-105K was smaller than that of SD-3B, but it shared same varying trend with SD-3B. Correlation analysis showed there was a good correlation between the five-day average data of FD-105K and SD-3B. F and t test between the FD-105K and SD-3B showed that the variance and mean of the radon data were different. It can be concluded that FD-105K is better than the SD-3B in the aspect of instrumental stability.
