We can rebuild the network packets and encryption and decryption data and many other important operations of network security in the layer . in addition , that can elevate the efficiency of the whole system 实现了对现有的协议栈增加了过滤层,并且可以在该层中实现封包重组,加密解密等网络安全方面重要的操作。
To facilitate drainage of groundwater and to maintain water flow , permeable rocks will be used for recompaction . filter layer and weepholes will also be installed . these will guarantee the normal flow of groundwater 为促进排水及保持正常水流,工程将使用具渗透性的石块作重新压实,同时安装过滤层及疏水孔,以确保地下水仍可如常流出。
Based on the experiment of dust removal in a granular layer at normal temperature and the analysis of the experimental results , the influence of filter particle diameter , layer thickness and filtration velocity on the dust removal efficiency was researched 摘要在常温下,采用固体颗粒层进行过滤除尘的实验研究,并对实验结果进行分析,探索了过滤介质粒径、过滤层厚度和过滤速度对除尘效率和床层压力差的影响。
An antifungal protein , named as b16 , was purified from the supernatant of the fermentation broth of strain 041381 by 80 % saturation ammonium sulfate , desalt and gel filtration on sephadex g - 75 , which with molecular weight at about 30 - 40 kd on the basis of sds - page 菌株041381发酵上清液经70饱和度硫酸铵沉淀,透析脱盐, sephadexg - 75凝胶过滤层柱,得到活性物质b16 。以sds - page胶为基础进行电泳分析, b16的分子量为30 - 40kd 。
The special ring - type with three - dimensional depth of a product of function of the products is filtered layer , can stop sand one above 0 . 06mm , and is developing into the steady sand cake constantly , form the protective screen of the second dish of sand control , it is particularly remarkable to block sand performance 产品作用本产品特殊的具有立体深度的环状过滤层,能阻挡0 . 06mm以上的砂粒,并不断发展成为稳定的砂饼,形成第二道防砂屏障,挡砂性能尤为卓越。
