RESULTS:①Cytocompatibility of PEG-PLA-PGL membranes with HUVECs: The observation result of phase contrast microscopy showed that, endothelial cells planted on the PEG-PLA-PGL membranes began to attach and stretch after being planted 4-6 hours. Three days later, cells grew in colonies rapidly, after 5 days, colonies began to fuse and seemed like cobble-stone. The cells were shuttle or polygon in shape after passages.

The mathematical models of the dynamics of the mass transfer based on the Nernst-Planck equation were established from which it is found that the different characteristics of the water decomposition between the cation and the anion exchange membranes or resins, is owing to the different potential gradient on the two kind of ion-exchange interfaces, which is further because of the difference between the structure and performance of the different membranes or resins, and is also because of the difference between transfer numbers of cation and anion ions.

根据所建立的传质数学模型方程获知在阴阳膜／树脂表面与水接触的界面层中发生的水解离的差异性，是在于离子交换界面电势梯度的差异，而这种差异又与膜与树脂的结构、性能以及阴阳离子在水溶液中的迁移数的差异有关。

The result shows that MWNT complex filtering membranes have 13.5% and 42.8% adsorptions for resorcin and alizarin red respectively. And, c-MWNT complex filtering membranes have 33.2% and 80.3% adsorptions for resorcin and alizarin red respectively. Comples filtering membrane have a great affinity for resorcin and alizarin red molecules. The membran been easily renewable, can be used repeatedly.

RESULTS: The AF cells cultured in different substrates were morphologically undistinguishable. Toluidine blue staining showed that there was also no difference between AF cells cultured on flexible silicone membranes and in plastic plates. The cells growing in different substrates expressed the same levels of collagen typeⅠ,Ⅱ and aggrecan mRNA and integrin β1. AF cells grew well on silicone membranes.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
