Filter medium is a fundamental part for filtration which is easily clogged in filtration process resulting in increase of medium resistance and poor performance of the filtration process.

过滤介质是过滤作业的基本部件，由于在过程中不断地被堵塞，介质阻力不断增加，过滤性能逐渐下降，以致于不能再继续使用。

The curves of the relation between efficient value of fibre filter medium, resistance and other variables have been plotted based on the air filtration theories and theoretical calculations.

本文还依据空气过滤理论，进行了大量的理论计算，绘制了关于纤维型滤料的效率、阻力和各有关因素之间的关系的曲线。
