摘　　要：研究多层复合滤纸和单层滤纸间透气率的关系。通过将单层湿纸页按一定顺序紧密叠合在一起并放入弧形干燥器内干燥的方法形成多层复合滤纸,探讨当各层纤维为单一纤维和多种纤维复配两种情况下的2层和3层复合滤纸的透气率与各单层滤纸透气率之间的关系,并从理论上推导出多层复合滤纸和单层滤纸间透气率存在如下关系:1/T=1/T1+1/T2+…+1/Tn,这对多层复合滤纸的研究有一定的指导意义。The relationship of the air permeability between the single-layer and multi-layer composite filter paper was studied. The multi-layer composite filter paper was made by placed the single-layer wet sheet close together in a certain order and dried in the Arc dryer, and the relationship of the air permeability between the double（triple） composite filter paper and its every single-layer at the case that each layer was composed of a single fiber or various fibers was researched. By the research we deduce the relationship between the air permeability of multi-layer composite filter paper and the air permeability of single-layer filter paper as follows： 1/T=1/T1＋1/T2 ＋... ＋1/T11, which would provide instructional information for the study of multi-layer composite filter paper.
