College of Textiles, Donghua University,air jordans, Shanghai 200051, China; 2. Shanghai Investigation Design & Research Institute. Shanghai 200434) Abstract: In the filter drainage system. Pore size and distribution of non-woven geotextile an important indicator of its non-woven geotextile and the permeability is directly related. Using PoissonPolyhedron theory. Based on previous research, analyzed the theory of non-woven geotextile pore size distribution and its maximum aperture, well under the law of Hagen-PoisseuiHe of the non-woven geotextile permeability of the pore size distribution and their relationships. Theoretical and experimental results of the vertical penetration of a better line Pi. Key words: non-woven geotextiles; units flat screen; maximum aperture; pore size distribution; vertical permeability transferred from page 37 PREPARATIoNoFULTRAFINEZr02PoWDERBYPRECIPITATIoNPanXiuhong, QiPing,ugg prezzo, ChenSha'OH2, RaoJian (1DepartmentofChemicalengineering, QingdaoUniversity, Qingdao266071; 2.DepartmentofPhysics, QingdaoUnlverNty,ed hardy clothing, ShandongQingdao266071 .
