摘要:随机取样某型空气过滤纸，实验测试样品的厚度、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，考察厚度、定量与紧度变异对空气过滤纸阻力和过滤效率实验测试数据的影响。研究结果表明，空气过滤纸厚度为0.395±0.08mm，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57.8±1.7g/m2时，定量W与阻力Δp之间的线性回归方程为Δp=2.64W，相关系数R2为0.82，定量对空气过滤纸的过滤效率测量值不存在显著性差异（α=0.05）；紧度为0.146±0.004g/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, basisweight, density, pressure and filter efficiency of random sampling of a certain type of air filter paper were tested by experiment, and the data were analyzed by using SPSS19.0 software, and the effects of thickness, basisweight and density variation on the measurements of pressure and filter efficiency were investigated. Research results suggest that when the thickness of air filter paper is 0.395±0.008 mm, there is no significant effect of the thickness on the measurements of both pressure and filter efficiency(α=0.05); when the basisweight is 57.8±1.7 g/m2, the linear regression equation between basisweight and pressure is Δp=2.63W+4.14 whose correlation coefficient R2 is 0.82, and there is no significant effect of basisweight on the measurement of filter efficiency (α=0.05); when the density is 0.146±0.004g/m3, there is no significant effect of the density on the measurements of both pressure and filter efficiency(α=0.05).
