Under the instruction of above-mentioned theoretical results, in the thesis chapter 10, the strongly electron-withdrawing anion, C_5O_5~(2-)[dianion of croconic acid (4,5-dihydroxycyclopent-4- ene-1,2,3-trione)], was chosen as the chelator to coordinate with boron to form lithium salt, which will yield high ionic conductivity solutions, and exhibit wide electrochemical stability windows and high thermal stability. As described in the chapter, two new lithium salts containing C_5O_5~(2-), lithium bisborate and its novel derivative, lithium borate for Li-ion battery electrolytes were synthesized.

在上述理论结果的指导下，论文第十章选择了克酮酸二价阴离子——具有很强的酸性、较好的芳香性、较大的电荷分散性、形成的配合阴离子具有较显著的共轭性——作为配体与B配位，合成了二种新的锂盐，通过实验测定了它们的结构和在有机溶剂中的溶解性。

The article proposed a method of the gas chromatographic determination for methyl cyanoacetate and intermidiates.

提出了用 6 。5 %吐温+ 5 。5 %邻苯二甲酸二壬酯涂于 10 2白色硅烷化担体上的不锈钢色谱柱，对氰乙酸甲酯合成的中间体和产品进行定量分析，取得较满意的效果。

The antibacterial activities of most of fractions were similar to the pomegranate peel extract.(7) Respiratory inhibition experiment showed that the respiration of thallus was inhibited mainly through the hexose monophosphate pathway, which leaded to be short of NADPH, and induced metabolic function dysfunction. Growth curve assay showed that the pomegranate peel extract inhibited cytodieresis in logarithmic growth phase. After exposure to the pomegranate peel extract, bacterial protein was analyzed by SDS-PAGE. The results showed that protein synthesis was inhibited, especially for large molecular weight protein.

7呼吸抑制试验结果表明，石榴果皮提取物主要是通过抑制HMP途径，导致还原力NADPH缺乏，引起代谢功能障碍，达到抑菌的目的；加药组和正常组金黄色葡萄球菌生长曲线的对比结果表明，石榴果皮提取物能够抑制金黄色葡萄球菌对数生长期的菌体分裂；SDS-聚丙烯酰胺凝胶电泳分析表明，石榴果皮提取物能够抑制菌细胞蛋白合成，尤其对菌体内大分子量蛋白作用最明显。
