When using urea-hydroperoxide as oxygent, just the trimethylphosphine adsorbed on the Lewis acid sites in TS-1 zeolite was oxidized. It further confirmed that the hydroperoxo-titanium species formed by the interaction between the titanium in Lewis acid sites and urea-hydroperoxide are the active oxidation center, and the titanium in the framework as Lewis acid sites enhances the oxidation ability of hydroperoxide. 3. Phenylacetaldehyde and benzaldehyde are found to be the major products in the catalytic oxidation of styrene over TS-1 zeolite, and styrene epoxide is not as speculated detected.

当以过氧化氢尿素为氧化剂时，室温条件下吸附在TS-1分子筛Lewis酸性位的三甲基膦即能被氧化，由此进一步证明，TS-1分子筛中由Lewis酸性位的骨架钛与过氧化氢相互作用形成的过氧化钛物种是三甲基膦氧化反应的活性中心，骨架钛作为Lewis酸中心提高了过氧化氢的氧化能力。

The logarithm difference values of partition coefficients of the compounds in butyl ether/water and in cyclohexane/water system were used for the measurement of the Lewis acidity, while the logarithm difference values of partition coefficients in trichloromethane/water and in tetrachloromethane/water system were used for the measurement of the Lewis basicity, and they were used successfully to differentiate the relative strength of Lewis acidity and basicity for 59 benzene and its derivates.

以化合物在正丁醚/水和环己烷/水溶剂体系中分配系数的对数差作为酸性指数，以其在氯仿/水和四氯化碳/水溶剂体系分配系数的对数差作为碱性指数，提出了一种新的度量有机物Lewis酸碱性的方法，按此方法成功地区分了59种苯系物Lewis酸碱性的相对强弱；并成功地将上述酸碱性指数引入定量结构—性质/活性相关研究之中，探讨了苯系物的正辛醇/水分配系数、水溶解度和土壤有机碳吸附系数等常见理化性质与其Lewis酸碱性间的相关性并建立了相应的定量模型，发现它们之间存在良好的相关性。

A catalytic amount of Ln(OSO2CF3)3 affected the stereochemistry of-MOPMAM during radical polymerization: the polydispersities of the polymers prepared in the presence of the Lewis acid were broader than those without the Lewis acid and the absolute value of specific rotation decreased in a majority of solvents.

结果表明，在-MOPMAM的聚合反应中，加入稀土盐可观察到明显的效应：在大部分情况下，随着三氟甲磺酸稀土盐加入量的增加，聚合物分子量分布变宽，旋光度也有很大幅度的下降。

Before Harry Potter was even thought of, Lewis Carrol, who was a mathematics don at Christ Church, used his surroundings as inspiration for Alice in Wonderland. JRR Tolkien and CS Lewis were also fellows in this inspirational place.

在罗琳还没构思《哈利波特》之前，Christ Church学院的数学教师Lewis就用这里的场景拍摄了《爱丽思梦游仙境》，许多人随后也采用了这里充满幻想的场景。

Five models were used to investigate the "Changdong"" s anti-tumor effect: mice S180 sarcoma solid model, mice liver cancer H22 solid model, mice Lewis lung cancer model, as well as human liver cancer QGY and colon cancer LOVO implanted in naked mice; mice liver cancer H22 was also used to evaluate the enhancive effect of "Changdong" when it was co-applied with other anti-tumor agent or with radiotherapy; The "Changdong"" s cytotoxic effect in vitro on such tumors as QGY, LOVO, lung cancer A549, breast cancer MCF-7, as well as mice leukemia P388 was observed through MTT method. And investigate the effect of "Changdong" on proliferation of spleen lymphocyte, on activity of NK cell and on synthesis of IL-2 in mice bearing Lewis lung cancer, respectively. With propidium iodide straining, cell aigptosis and cell circle were analyzed by flow cytometry. Result:"Changdong" has an evident tumor inhibitive effect on mice tumor model as well as human tumor implanted in naked mice with a quantity-effect relationship.
