However,aryl arenesulfonates and mesylates are attracting more interesting.

近年来，芳基磺酸酯和甲磺酸酯参与的交叉偶联反应日益受到关注。

The results show that for collectors of the same kind, their selectivity is in linear relationship with HOMO energy and can be predicted well. For collectors of different kinds, it can be concluded from shape of HOMO and atomic HOMO density that the selectivity of ethoxycarbonyl thionocarbamates is better than the one of xanthogen formates.

结果表明：对于同种类型的捕收剂，其选择性与HOMO能量呈线性关系，依据HOMO能量能较准确地预测这两种捕收剂的选择性能；对于不同种类的捕收剂，通过对HOMO形状以及组成原子的HOMO密度的讨论可知，乙氧羰基硫氨酯类捕收剂的选择性能要比黄原酸甲酸酯类捕收剂的强。

In this work, the interaction between umbelliferone and bovine serum albumin was studied by performing two different kinds of titration modes. The two spectroscopic data matrices were augmented, and then the information of experiment data was increased. The augmented experiment data matrix was analyzed by the MCR-ALS method. This procedure allowed the recovery of the concentration profiles for each species and the calculation of the ∶ ratio in the complex and the apparent equilibrium constant.

采用两种不同的试剂滴加模式对伞形花内酯与BSA的相互作用进行研究，对经典的荧光光谱数据矩阵加以扩展，增加了实验数据的信息量；进而应用MCR-ALS对该扩展的荧光光谱矩阵进行迭代计算，较好地分辨出作用过程中浓度变化趋势图，并计算出伞形花内酯与BSA的表观结合常数和结合比。

The results showed that:(1) 5'-nucleotide contents in yeast autolysate was slightly increased by adding RNase frommalted barley roots;(2) higher pH did not improve the 5'-nucleotide contents even in the presence of RNase from malted barleyroots, but at the pH 8.0, the addition of Acalase could increase the final yield, soluble protein contents and 5'-nucleotide inthe presence of RNase from malted barley roots.

酵母核酸酶的pH稳定性和温度稳定性均比麦芽根核酸酶的要差。这说明自溶法生产酵母提取物时，即使外加5'-磷酸二酯酶不能有效提高呈味核苷酸的原因并非由于外加的5'-磷酸二酯酶性质不稳定，而是另有其它原因。

In chapter three, the activating agents of ytterbium have been examined. Barbier-type reaction promoted by ytterbium metal was examined. The experimental results shown that the yield of Barbier reaction of imines with allylic bromide promoted by ytterbium is higher than that of aldehydes and ketones with allylic bromide under the same reaction conditions. In this chapter, the reductive cleavage of Se-Se and S-S bond induced by ytterbium metal was also studied.
