计算了氨基酸衍生物对映体以及辛可纳非对映异构体分离过程的热力学参数并利用前沿色谱法测定了辛可宁和辛可尼丁在盘状分子印迹整体柱上的离解平衡常数。

Diastereomers of cinchonine and cinchonidine were separated in pressure-assisted capillary electrochromatography mode, and the resulted separation efficiency was much higher than that obtained in high performance liquid chromatography.

采用压力辅助电色谱模式拆分了非对映异构体辛可宁和辛可尼丁，其柱效远高于其在HPLC中拆分的结果。

The increase in MAC for cyclopropane was unexpected, because published reports find only minimal actions at 122 GABAA receptors whereas isoflurane provides a large enhancement.

环丙烷对突变鼠最低肺泡有效浓度的增加出乎我们的意料，因为外界报导在α1β2γ2 γ-氨基丁酸 A 受体这一异氟烷作用最强的地方，环丙烷只有极微弱的作用。

The main technological feature of the product is that it is formed by fermenting the bean milk or powder, bean recovering milk mixed with glucose, fructose, enforced soybean isoflavone with lactobacillus, especially Lactobacillus helveticus TUST005 and diketone streptococcus.

其主要技术特点是大豆乳或大豆粉、大豆蛋白复原乳混合葡萄糖、果糖或果葡糖浆，强化大豆异黄酮，经过乳酸菌，特别是瑞士乳杆菌TUST005和丁二酮链球菌的发酵，形成凝乳的食品。

AIM:To extract pueraia isoflavone and soyisoflavones with n-butanol by means of inner ebullition from Radix puerariae lobatae.

用少量乙醇溶液润湿葛根粉末使其中的葛根异黄酮充分解吸，然后加入一定温度的含水正丁醇溶液，使渗透到葛根组织内部的乙醇沸腾，强化提取过程。

Sugar alcohols such as mannitol, sorbitol, xylitol, erythritol, lactitol, maltitol, isomaltitol are applied in confectionery products, chewing gums, and mixed juices. In this research, capillary zone electrophoresis was used to build up a basic analysis model to simultaneously analyze sugar alcohols.

糖醇的种类可分为单糖醇与双糖醇，主要应用的单糖醇有甘露糖醇、山梨糖醇、木糖醇、丁四醇，而双糖醇则有乳糖醇、麦芽糖醇和异麦芽酮糖醇(isomaltitol，又称为巴糖醇，palatinitol)等。

The properties of single-chain and pauci-chain polystyrene microspheres and recent results on the electron microscopy and selected area electron diffraction of single-chain monocrystals of polyethylene oxide, isotactic polystyrene, cis-1, 4-polybutadiene and guttapercha are presented and discussed.

介绍和讨论了单链和寡链聚苯乙烯玻璃体微球的性质以及聚环氧乙烷、全同立构聚苯乙烯、顺-1， 4-聚丁二稀、反-1， 4-聚异戊二烯单链单晶电子显微镜和选区电子衍射观察的最新结果。

Trees, monoecious or dioecious; indumentum of simple or T-shaped hairs, often sparse.

乔木，雌雄同株或异株；具单毛或丁字毛，通常稀疏。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
