The supported WP catalysts showed considerable activity in HDS reaction of dibenzothiophene and HDN reaction of quinoline. The ibenzothiophene HDS activity and quinoline HDN activity of the spported WP catalysts synthesized by co-impregnation method was better than that synthesized by mixing method. The HDS and HDN activities of 25～30% WP catalysts synthesized by co-impregnation method and reduced at 650～750℃ were better than those of the corresponding sulfurized catalyst.

The results showed that as the leaves development, POD activity on leaves of the male sterility line significantly differed from that in the maintainer and restorer line. The CAT activity had little difference in tasseling stage, SOD activity in the male sterility line was higher than its maintainer and restorer line, and the difference was significant in every stages.

Close correlation was also found between the SOD activity and the cell density and substance accumulation. When SOD activity is higher or lower than 0.710×10^8 cells^(-1)min^(-1), the cell density and accumulation of 13-carotene and protein were lower. When SOD activity reached 0.710×10^8 cells^(-1) min^(-1), the cell density, and accumulation of β-carotene and protein were the highest.

盐藻SOD活性与细胞密度及物质积累关系密切：在SOD活性为0.710×10^8 cells^(-1)min^(-1)左右时，盐藻细胞密度、β-胡萝卜素和蛋白质的积累量都最高，而在SOD活性较低或较高时，盐藻细胞密度、β-胡萝卜素和蛋白质的积累量都较低。

Because of the bonded crown ring the catalytic activity of complexes can be improved and the induce period of the oxidation for p-xylene to p-toluic acid was shortened from～ 10h to 0.5～5h, the fashion and position of the bonded crown ring as well as the distance between the crown ring and activity center have distinct influence on the catalytic activity of complexes.

结果表明：1。键连的冠醚环均能显著提高催化活性，并大大缩短反应诱导期5-10h，使TOF从21～60提高到152～222，约增加了5～7倍；冠环的键连方式和部位以及与活性中心的距离对催化活性影响明显；2。

Result: B-2 can increase abdominal cavity macrophage phagocytic activity significantly (p.001) B-1 can increase abdominal cavity macrophage phagocytic activity (high dose of B-1: P.01, low dose of B-1: P.05). Only high doses of S. sphenanthera coarse polysaccharides can increase phagocytic activity (phagocytic index p.05) and show dose-dependent augmentor effects.

结果：北五味子脱蛋白粗多糖能极显著增强腹腔巨噬细胞吞噬功能(p.001)，未脱蛋白粗多糖能显著增强腹腔巨噬细胞吞噬功能（大剂量组p.01、小剂量组p.05），而南五味子粗多糖只有大剂量组能增强腹腔巨噬细胞吞噬功能（吞噬指数p.05），并呈一定的量效关系。
