10 7 Cell/ml inoculation quantity would result in adequate contents of higher a lcohols and biacetyl and appropri-ate alcoholicity and fermentation degree.

设计了3个不同接种量，试验其对酵母代谢副产物含量的影响，结果表明，控制接种量在2.0×107个/ml时，对啤酒风味物质高级醇和双乙酰含量合适，并可使啤酒有适当的酒精度和发酵度。

Influences of the reaction time,molar ratio,type of solvents and their volume on the yield of alcoholysis products are investigated.

探索了反应时间、物料摩尔比、溶剂种类和用量对醇解产物收率的影响。

The key technology of "fattyacid-oil process" in production of alkyd resin is the alcoholysis of oils. The alcoholysis of fattyacid-oil is the result of esterification of fatty acid and alloholysis of oils, of which the medium effect of esterified product of fatty acid and polyols will promote the alcoholysis of oils with polyols.

制造醇酸树脂的"脂肪酸－油法"的技术关键依然是油脂的醇解，整个脂肪酸－油脂体系的醇解是脂肪酸酯化与油脂醇解并行反应的结果，其中，脂肪酸与多元醇的酯化产物的介质效应有力地促进了油脂与多元醇的醇解反应。

The qualitative analysis of three kinds of aldehyde isomers has been reported.

本文介绍了三种醛异构体的GC－ MS测定，并对某些质谱开裂产物的产生机理进行了解

The key steps to determine the stereoselectivity of products are the Michael reaction step and aldol reaction step.

4反应过程中的Michael反应与羟醛缩合反应是决定产物立体选择性的决定性步骤。

设计合成了一种NOBIN衍生的手性配体，初步研究了该手性配体的双核锌配合物在对硝基苯甲醛和丙酮的不对称直接醇醛缩合反应中的催化应用，20℃和20mol％催化剂量下，获得了32.5％ee和72％收率的产物。

The catalytic efficiency of 7a was the best when acetone was used as Aldol donor, and the Aldol products were obtained with up to 78% ee in the presence of 10 mol% 7a.

对丙酮与醛的反应，7a的催化效果最好，在10％催化剂存在下产物ee值高达78％。

The brown color of lecithin is largely the result of heathing the oil during solvent stripping and is to be the result of an aldehyde-amine reaction or aldol condensation.

大豆磷脂中的褐色物质可能是毛油在汽提时生成的，据认为是缩醛产物。

Birch Reduction, one of the most powerful synthetic methodologies available to organic chemists, provides a bridge between aromatic and aliphatic compounds and makes a huge arsenal of aromatic derivatives readily available for construction of alicyclic molecules, which are possibly converted into various natural products.

Birch还原是联接芳香族和脂肪族化合物的桥梁，它使许多芳香族衍生物成为合成脂肪族化合物，尤其六元脂环天然产物的起始原料，因此Birch还原是有机合成中很有用的方法。

As the product of history, it is the fact that alienation is still living in virtual society.

作为历史发展的产物，虚拟社会中人的生存异化的问题依然客观存在。

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