The distribution coefficient of oxalic acid was larger than that of glyoxylic acid,and both of them decreased with the pH. The selectivity of oxalic acid to glyoxylic acid also decreased with pH.

在本实验的条件范围内，草酸的分配系数较乙醛酸大，且随溶液pH值的增大而下降，草酸对乙醛酸的分离系数随pH值的增大而减小。

After the above agent all the hypothesis of the optimization assembly, versus dynamic variance that different the growing period air ratio was studied, the air proportion affecting organisms used in two-step fermentation process and decide the air proportion for different cultivating period and investigate to what extent air may affect the organisms used in two-step fermentation process so that the fair term was created for 2- keto -L- gulonic acid of the accumulation.

在以上因素都优化组合的前提下，对不同生长期空气比的动态变化研究，确定了混合菌培养过程中，根据实际单罐批的生长情况，优化控制空气比可以协调巨大芽孢杆菌﹑氧化葡萄糖酸杆菌之间关系，为2-酮基-L-古龙酸的积累创造良好的条件。

The progress on chemical synthesis and biosynthesis of levulinic acid and 5-aminolevulinic acid(5-ALA) were discussed.

基于生物质资源的利用和开发，论述了乙酰丙酸的制取、5-氨基乙酰丙酸的化学合成与生物合成，阐述了其在医药、农业等方面的应用，讨论了发展趋势和亟待解决的问题。

The increase of salt content improved the production of palmitic acid and linoleic acid, but reduced that of oleic acid. The influence of salt content on stearic acid and linolenic acid was not singnificant.

土壤含盐量的增加，促进棕榈酸、亚油酸的生成，抑制油酸的生成，但硬脂酸、亚麻酸的变化受土壤盐含量的影响不明显。

UV-Vis spectra show that the absorbance values at characteristic wavelengths of the multilayer films increase almost linearly with the number of chitosan/PTA bilayers, suggesting that the deposition process is regular and highly reproducible from layer to layer. XPS and FTIR spectra confirm the incorporation of chitosan and PTA into the films. AFM images indicate that the surface of the multilayer films is rough. The result of CV shows that the multiplayer films maintain good electrocatalytic activity of phosphotungstate acid.

UV-Vis结果显示多层膜在特征吸收峰处的吸光度数值随膜双层数增加逐渐增大，呈良好的线性关系，表明多层膜是均匀组装的；XPS和FTIR结果证实了壳聚糖和磷钨酸被组装到膜上，AFM图形显示膜表面有一定的粗糙度，CV结果说明多层膜保留了磷钨酸的电化学性质。

The results show high selectivity when the temperature is controlled at 50 CC , and the nitrated reaction time is 90 mm, toluene is nitrated by using 95% nitric acid as nitrating reagent at the presence of acetic anhydride, 1.0g silicotungstic acid catalyst is calcinated at 300℃ for 1.5h. The o/p (ratio of ortho to paro isomer of toluene nitration) ratio is 0.89 in product distribution of toluene nitration, lower than 1.67 using sulfonitric acid as catalyst. The yield of products is 91.6%.
