On the basis of the analytical results of infrared spectrometry,paper chromatography,tyrosine color development reaction and the assay of anti-acid buffer capability,we confirm that chlorine dioxide in stabilized solution with sodium percarbonate as stabilizer exists in the form of chlorition (ClO2-) and exists in NaHCO3-Na2CO3 buffer system. When the stabilizer is sodium perborate,chlorine dioxide may be retained in the solution comprised of H3BO3-Na2B4O7 as a labile complex.

通过对几种样品的红外光谱分析、纸色谱分析、酪氨酸显色反应及抗酸缓冲能力的测定，证实在以过碳酸钠为稳定剂的稳定液中，ClO2以亚氯酸根离子(ClO2-)形式存在，并处在一个由NaHCO3-Na2CO3组成的缓冲体系中；在以过硼酸钠为稳定剂的稳定液中，ClO2可能是以活性配位化合物的形式存在，并处在由H3BO3-Na2B4O7组成的缓冲体系中。

The pharmacological evaluation of these target compounds is in process.

Owing to the abroad application of Candida rugosa lipase in the resolution of racemic aminoacides, the prepared lipase was used in the resolution of phenylglycine and tert-leucine. Through the optimization of the reaction conditions, such as reaction substrate, pH, temperature, ion strength and additives, enantiomeric excesses for phenylglycine and tert-leucine reached 96% and 90.1%, respectively, enantiomeric ratio came up to 28. 9 and 15. 4, respectively.

鉴于该酶广泛应用于手性化合物的拆分研究，本论文中选用了两种手性氨基酸作为拆分对象，通过对反应体系中一系列条件的优化，包括底物、pH、温度、离子强度以及添加物的使用，苯甘氨酸和叔亮氨酸的对映体过量值分别达到96%和90.1%，对映催选择率分别达到28.9和15.4。

In general, the phosphoamino acid esters were unable to transfer their phosphoryl group to other hydroxyl nucleophiles even with the presence of imidazole, but the N-phosphoserine and threonine esters were two exceptions.

二、测定了部分磷酰化D—氨基酸的磷酰基转移反应速率常数，并对外消旋化合物的酯交换反应进行了旋光度跟踪，发现磷酰化丝、苏氨酸的对映体有明显的区别。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
