pore membrane

The results indicated that the eggshell structures of four birds were much similar with other bird species, which were outer layer, spongy layer, cone layer, mammilla, shell membrane layer and pore channels through the shell from outer to inner.

结果显示，这四种鸟类的卵壳结构与其他鸟类的基本相似，由外而内依次为表层、海绵层、锥体层、乳突、壳膜层及贯穿卵壳的气孔道等。

Results showed that PVDF membrane had stronger resistant pollution ability to orange juice filtrated by 150 sieve pore and centrifugalization than that by 80 sieve pore filtering.

结果表明：PVDF膜对150目筛滤离心过滤后的果汁表现出较强的抗污染能力；

Botulinus toxin from a clostridium botulin fermentation broth was separated and purified by membrane filtration technology. To remove the bacteria from the fermentation broth, we chose a 0.65 μ m pore size microfiltration membrane, reaching a removal ratio of 100%.

报道了把膜分离技术应用于肉毒发酵液的纯化.用孔径为0.65μm的微滤膜对发酵液进行除菌，除菌率达到100%；

The pore size of mesoporous membrane is between the reverse osmosiss and the ultrafiltrations.

纳米孔膜的过滤类似于反渗透和超滤,均属于压力驱动的膜过程,但其传质机理却有所不同.

A new method for the calculation of average pore size of UF membrane was advanced.

利用扫描电镜法测定超滤膜底表面上总孔面积与该底总表面积之比,再结合哈根——泊肃叶定律来推算超滤膜皮层的平均孔径.
