A computer-aided local transient flow property measuring system was developed using a high speed CCD camera coupled with optical fibers in order to study the Gas-liquid-solid three-phase jet loop reactors. SnO2 crystal films were orientally deposited on the alkoxysilane molecule-coated hydroxyl glass substrates so as to prepare surface-marked particles as the tracers. An image analysis system was established to identify different phases. Stroboscopic photography was utilized to extend the measure range. The developed measuring and analysis system was capable of determining accurately the local transient flow property in a G-L-S jet loop reactor. Based on the above system, local transient flow properties of gas, liquid, and solid phase were measured and studied the influences of fluid property, operation and configuration parameters on the reactor.

目的：类风湿关节炎(rheumatoid arthritis，RA)是一种慢性系统性疾病，其主要病理改变是滑膜炎和血管翳形成及其相关的血清组织中多种细胞因子、抗原抗体和粘附分子等的变化，而细胞因子是RA炎症和损伤的重要介质，对RA患者外周血及滑液中细胞因子改变已有大量研究，已证明多种细胞因子参与RA的病变过程。

1 Water stored in soils. 2 One of the most important elements involved in pedological processes and plant growth. There are three basic form-: water adhering in thin films by molecular attraction to the surface of soil particles and not available for plants is termed hygroscopic water. b Water forming thicker films and occupying the smaller pore spaces is termed capillary water.

储藏在土壤中的水分，2）在土壤过程和植物生长中最重要的元素之一，有三种基本形态-：（s：a 藉分子间引力以薄膜形式附著在土壤颗粒表面的水分，不能被植物利用，称为吸湿性水， b形成厚的水膜填充在较小土壤气孔中，称为毛细管水。

Based on these observations, we propose that the periplasmic proteins have been evolved to resist the formation of aggregates when subjected to various denaturing conditions and molecular chaperones may thus not be needed in periplasm.

根据这些发现，我们提出假说：膜间质蛋白在恶劣环境条件的选择压力下进化出对各种变性条件所诱导聚集的抗性，而不需要分子伴侣蛋白的有效保护。
