摘　　要：利用邻苯二甲酸二辛酯(DOP)多分散气溶胶,采用扫描迁移粒径仪分析气溶胶全粒径谱的方法,研究了2μm不锈钢膜过滤材料在串级条件下的最大穿透粒径(Dmax)的有关特性。研究结果表明:滤速一定时,相同孔径的串级滤材的最大穿透粒径与单级滤材基本是一致的;各单级滤材的最大穿透粒径随级数的增加向小粒径方向移动;二级、三级串级过滤时,最大穿透粒径具有随滤速的增加向小粒径方向移动的规律。Using polydisperse DOP aerosols and The Scanning Mobility Particle Sizer, the most penetrating particle size （Dmax） of 2im multilayer stainless steel filter material was studied. The results show that the D of multilayer filter material is same as the singer layer filter material under one certain filtration velocity, the D xof multilayer filter material decrease as increaseing of the amount of layers. For two-ply filter and three-ply filter, the Dx decrease as increaseing of filtration velocity.
