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。

In the aqueous solution, Cu precipitates with ammonium thiocyanate and tetradecyl benzyl dimethylammonium chloride .

This paper investigates that the different composition of the headspace gas and polluted sediment slurries can affect the ratios of degradation on benzoic acid, toluic acid and phthalic acid isomers. We found that a sediment slurry which has been polluted can develop a stronger microbial degradation.

此篇文章主要是探讨不同上层气体之组成和被污染过之底泥可影响苯甲酸、甲基苯甲酸异构物及苯二酸异构物被分解的速率，我们发现被污染过之底泥可发展出较强之微生物降解力。

Thus. Treatment of CR1R2=C=CH2 (R1 = R2 = Me; R1 = H, R2 = n-Bu; R2 = Ph; R2 = cyclohexyl; R2 = cyclopentyl, R2 = C6H5O, R2 = 2-IC6H4O, R2 = 4-IC6H4O) with bisdiborn in the presence of Pd2 (5 mol %) and 3-iodo-2-methyl-2-cyclohexen-1-one (5 mol %) in toluene at 80 oC gave products bearing both vinylic and allylic boron moieties in good to excellent yields.

Allogeneic and syngeneic fresh bone, autolyzed antigen-extracted bone, bone matrix gelatin, demineralized bone matrix were implanted into the muscle pouch of mice, at different times after implantation, the immunological, histological and alkaline phosphatase assay were conducted. The results revealed that all four kinds of allogeneic implants activated specific cellular and humoral immune responses, most notably in fresh bone group, the AAA, BMG and DBM inhibited the proliferation of the lymphocytes in vitro and BMG had the most powerful inhibiting action, allogeneic AAA, BMG and DBM might induce heterotopic osteogenesis in vivo, however, there were obvious difference in ALP and histomorphometry between allografts and isografts.
