Corn stalk pretreated by dilute sulfuric acid was hydrolyzed by the dosages of 20 FPIU/g Trichoderma reesei cellulase and 4 IU/g β-glucosidase at the substrate concentration of 100 g/L for 48 h, the concentration of cellobiose and glucose in hydrolysate were 1.12 and 42.68 g/L, respectively, the yield of enzymatic hydrolysis and the ratio of fermentable sugar were 62.85% and 97.44% respectively.

底物质量浓度为100g/L的稀硫酸预处理玉米秸秆，经酶用量为20 FPIU/g的里氏木霉纤维素酶和4IU/g的β-葡萄糖苷酶水解48h，水解糖液中纤维二糖和葡萄糖质量浓度分别为1.12和42.68g/L，纤维素水解得率和可发酵性糖的比例分别为62.85%和97.44%。

Trehalose is a disaccharide consisted of two subunits of glucose withα-1,1 glucosidc bond .It has biology functions of unique anti-frozen and anti-dehydration.

海藻糖是由2分子的葡萄糖经α-1，1糖苷键结合而成的非还原性二糖，具有独特的抗冷冻和抗脱水的生物学功能。

As in disaccharides, these units are held together by glycoside linkages, which can be broken by hydrolysis.

例如二糖中的单糖单元通过糖苷键连接，这种键会经水解而断裂。

The result demonstrated that mannitol was the best protective substance, followed by raffinose,trehalose and melibiose, L-cysteine, xanthan gum and glycerol showed slightly protective ability.

结果表明，甘露醇对α-半乳糖苷酶的保护效果最好，其次是棉籽糖、海藻糖和蜜二糖；L-半胱氨酸、黄原胶和甘油也起到了较好的保护作用。

By treatment with TMSOTf, peracetylated chitobiose,-triose, and -tetraose weretransformed into corresponding oxazolines.

全乙酰化的几丁二糖，三糖和四糖在TMSOTf处理下转变成相应的〓唑啉化合物。

There are two positive results, proton and sodium that has been reported previously, and three candidates including succinate, phosphate and melibiose that was found in this study.

根据节点连结度的分析，找到了五个候选协同输送系统中的中心小分子，其中两个为已知的阳性资料，氢离子与钠离子，其余三个分别为琥珀酸盐，磷酸，蜜二糖，其中以蜜二糖为中心的输送系统只有一个，并不符合本篇所定义的协同输送系统，故舍弃之。

In order to decrease toxicities of retinods and enhance pharmacal effects and gain the relative derivatives with better curing effect and selectivity, structures of retinoic acids were modified by inducing glycosyl groups in this paper.

方法一是在氢氧化钾存在下，以4-二甲氨基吡啶做相转移催化剂，将溴代-O-乙酰基葡萄糖(5a)、溴代-O-乙酰基木糖(5b)、溴代-O-乙酰基乳糖(5c)和溴代-O-乙酰基麦芽糖(5d)分别与异维A酸反应制得1-O-异维A酰-乙酰基单糖(6a，6b)和1-O-异维A酰-乙酰基二糖(6c，6d)，收率为53～65%。

The mass ratio of glucosides was figured out with the unreact ratio of glucose and polysaccharides detected by chemical method.

结合用化学法测得的未反应葡萄糖、生成的二糖多糖的质量百分含量，可计算出AEO3糖苷化后混合物中的糖苷化物的质量百分含量。
