摘 要:利用2022年实验室湿度传感器检定数据,从相关性、方差齐性检验、差值分布、测量误差、标准差等方面对DHC2-A和DHC2两种湿度传感器进行对比分析。结果表明:(1)DHC2-A和DHC2各检定点相关系数最大为0.48,线性相关不显著。双样本方差齐性检验得到P值0.218 8,大于检验标准0.05,DHC2-A和DHC2总体样本无显著差异;(2)DHC2-A和DHC2差值集中出现在–1%~4%处,占样本比例约为79.1%,峰度系数为0.11,偏度系数为0.68,曲线呈尖峰状和正偏离。在湿度不高于50%时,DHC2-A和DHC2测量性能非常相近,湿度在75%~95%时,DHC2-A测量值大于DHC2测量值,在95%点上差值平均值为4.5%。(3)DHC2-A测量误差集中在±2%之间,占总样本的89.6%,在95%湿度点上,DHC2误差平均值比DHC2-A小4.51%。DHC2和DHC2-A标准差在各检定点相近。(4)我国湿润地区宜安装DHC2-A型,半湿润地区安装DHC2和DHC2-A均可,干旱和半干旱地区宜安装DHC2型,这有利于气象台站合理使用湿度传感器,为气象预报和服务提供更准确的数据。Comparative analysis was conducted on DHC2-A and DHC2 humidity sensors from the aspects of correlation,homogeneity of variance test,difference distribution,measurement error and standard deviation by using the 2022 laboratory humidity sensor calibration data.The results showed that the maximum correlation coefficient between DHC2-A and DHC2 was 0.48.The homogeneity of variance test with two samples obtained a P-value of 0.2188,which is greater than the test standard of 0.05.There was no significant difference in the population samples between DHC2-A and DHC2.The difference between DHC2-A and DHC2 is concentrated at–1%to 4%,accounting for about 79.1%of the sample.The kurtosis is 0.11 and the skewness is 0.68.The curve shows a sharp peak and positive deviation.The measurement performance of DHC2-A and DHC2 is very similar when the humidity is not higher than 50%.The measured value of DHC2-A is greater than that of DHC2 when the humidity is between 75%and 95%.The average difference at the 95%is 4.5%.The measurement error concentration of DHC2-A is between±2%,accounting for 89.6%of the total sample.At the 95%,the average error of DHC2 is 4.51%lower than that of DHC2-A.The standard deviations of DHC2 and DHC2-A are similar at each checkpoint.DHC2-A can be installed in humid areas of our country.DHC2 and DHC2-A can be installed in semi humid areas.DHC2 type should be installed in arid and semi-arid areas.This is beneficial for stations to use humidity sensors reasonably and provide more accurate data for me-teorological forecasting and services.
