Filtration coefficient ratio depends mainly on the air dust and the content of solid particles.
过滤系数比值主要取决于空气中灰尘和固体颗粒的含量。

The experiment reveals that the variation of UFE numbers is only dependent on the volume-specific deposit of filter, the effects of filtration velocity, bed depth and ALT ratio are not evident.
It has deduced the mathematical function of the sediment void ratio on the basis of stress and structure analysis, and then the mass and volume conversion of deep bed filtration sediment is given.
