摘　　要：在纸张匀度指数值较稳定的情况下，对纸张匀度指数分量和透气度之间的关系进行了规律性的探讨。结果表明：纸张中纤维絮聚团尺寸大于3mm的部分的匀度指数分量对透气度的影响呈二次曲线的关系，而尺寸小于3mm的部分无明显规律，且尺寸为6～16mm的纤维絮聚团的匀度指数对透气度的影响大于尺寸为3～6mm的部分产生的影响；随着纸张定量的增加，匀度指数分量与透气度之间的关系越加明显。At the condition of stable formation index, the relation between formation index and air permeability of paper was analyzed. The results showed that the formation index of the fiber flocks whose sizes were greater than 3mm had a secondary curve relationship with air permeability,but there was not similar rule between the formation index of the fiber flocks smaller than 3mm and the effect to air permeability, and the effect created by the fiber flock size in 6-16mm on the air permeability is greater than those in 3-6mm fraction. The rule of the relation between formation index and air permeability is more clear with increase of paper base Weight.
