The beta ratio is normally used to characterize filter media because it is more sensitive to small changes in the higher efficiency range than is the efficiency.The beta ratio and efficiency often used to define the nominal rating for a depth filter medium.Manufacturers may define the nominal rating for a depth filter medium.Manufacturers may define the nominal size of their media as the size spherical particle for which the medium captures 98%.Hence if a filter captures 98% of 2-m spherical particles,then the filter may be given a nominal rating of 2 m.Different filter media suppliers may use different percentages other than 98% to characterize their media.The beta ratio and efficiency only considers the capture of particles.The quality factor considers the capture of particles as well as pressure drop.Ideally,the pressure drop through a depth filter is proportional to the thickness of the filter.Conversely,the log of the particle penetration(ration of the number of particles passing through the filter to the number challenging the filter)is proportional to the thickness of the filter.Hence,the quality factor

eta版的比例通常是用来描述过滤介质,因为它是敏感的小变化范围要比效率更高的效率.测试版比和效率通常用于定义名义等级来深度过滤介质.制造商可能定义名义等级来深度过滤介质.制造商可能定义标准尺寸的大小媒体的球形粒子的捕获98%的媒介.因此,如果一个过滤器捕获98%的全身的球形颗粒,然后过滤器可以给出的评级m.Different名义2过滤介质的供应商可能使用不同的百分比除了98%来表现其媒体.测试版比和效率仅考虑捕获的粒子.质量因素考虑的捕获粒子以及压降.理想情况下,压降通过深度过滤是成正比的厚度的过滤器.相反,日志的粒子渗透(配给的数量的粒子通过过滤器,以数字挑战过滤器)是成正比的厚度的过滤器.因此,质量的因素
