The grains are much finer insize and much compact in arrangement as the result of ion bombardment,which is useful to improve the performance of the coatings.
Results show that coating at higher temperature can improve the performance of membranes,coating process with the combination of concentrated sol and diluted sol not only improves coating efficiency,but also improves the performance of membranes.
This paper analyses qualitatively the effect of biasing voltage on the composition of the surfacial film in sputtering, and gives out the results from the Auger analysis, X-ray diffraction, scanning electron microscope energy spectrum and observation on the surfacial composition of indium tin oxide (ITO) film under different biasing, voltages, which concludes that the film performancs will be increased when biasing voltage ranges from O to -100 V.
Because single membrane material can’t have simultaneously favorable hydrophilicity, membrane formation, thermal stability, chemical stability, acidityproof and alkalescenceproof, microbial erodent-resistant, oxidation-resistant, preferable mechanical intensity and so on, adopting material and surface modification methods is the key to solve the problem.
coating membranes with the combination of concentrated sol and diluted sol not only improves coating efficiency,but also improves the performance of membranes;
Utilizing the feature of quick response of HVDC to improve the performance of AC/DC system has become the emphasis to be researched.
The purpose of this paper is to improve the performance and robustness of VAD by introducing visual information.
In order to predict and improve the performance of networked storage systems, this paper explored the relationship between the system I/O response time and its performance factors by quantitative analytical method.
Simulation results prove that the proposed algorithm can significantly improve the performance of a multicode system.
In addition, the multifunction system concept was introduced to improve the performance of CCLC with solar energy.

When the composite glass membrane is produced via a sol-gel process, the sol system of TEOS-H3BO3 is applied. It is found that through appropriate drying control of the chemical additive (DCCA), the cracks accompanying with preparation of the membranes in point can be inhibited. And the blocking extent of the substrate can be efficiently reduced by hydrophobic treatment as well.
This paper reviews the recent progress of membrane materials and membrane-forming technologies in the pervaporation separation of organic solvent mixtures in the world. It points into that ultrathin and dense composite membrane preparation is an important and effective way to improve the pervaporation performance.
