Based on the former researchers' works,the theoretical pore size distribution and maximum pore size of nonwoven geotextile are studided by means of Poisson polyhedron theory.
利用PoissonPolyhedron理论 ,在前人研究的基础上分析了非织造土工布的理论孔径分布及其最大孔径 ,并根据Hagen Poisseuille定律探讨了非织造土工布的孔径分布与其渗透性能间的关系 ,理论计算的垂直渗透与实测结果有较好的一致
The effects of change of porosity on relative gas permeability and maximum pore size are investigated in this paper.
研究了Ni纤维毡孔隙度的变化对其透气性能和最大孔径的影响。
It was found that the content of additive can greatly improve the permeability of the sintered plates,but the maximal pore size is also enlarged.
研究结果表明:添加剂用量可以显著提高载体的透气度,但最大孔径也较大(3μm)。
