摘要:通过测试某型号空气过滤纸的厚度、定量、紧度、阻力和过滤效率，利用统计分析软件SPSS19.0进行数据分析，考察空气过滤纸厚度、定量与紧度波动对阻力和过滤效率的影响。结果表明，空气过滤纸厚度范围在0.376~0.420 mm时，对其阻力和过滤效率测量值均不存在显著性影响（α=0.05）；定量为55.2～59.8 g/m²时，对阻力测量值有显著性影响（α=0.05），定量W与阻力Δp之间的线性回归方程为：Δp=2.641W，相关系数R²为0.817，定量对空气过滤纸的过滤效率测量值不存在显著性影响（α=0.05）；紧度为0.139～0.152 g/m³时，对阻力和过滤效率测量值不存在显著性影响（α=0.05）。

Abstract:The thickness, basis weight, density, filtration resistance and filter efficiency of the random samples of a certain type of air filter paper were tested, and the data were analyzed by using SPSS19.0 software, and the influences of thickness, basis weight and density fluctuation on the measurements of filtration resistance and filter efficiency were investigated. Research results suggested that when the thickness of air filter paper was in 0.376~0.420 mm, there was no significant effect of the thickness on the measurements of both resistance and filter efficiency(α=0.05); when the basis weight was in 55.2~59.8 g/m²,it had a significant effect on resistance, and the linear regression equation between basis weight and resistance was Δp=2.641W， whose correlation coefficient R² was 0.817,and there was no significant effect of basis weight on the measurement of filter efficiency(α=0.05); when the density was in 0.139~0.152 g/m³, there was no significant effect of the density on the measurements of both resistance and filter efficiency(α=0.05).
