酸性反应

The produces distribution is different with the difference of acidity of sample.

随着样品酸性的变化，反应产物的分布亦不相同。

The synthetic condition s of benzaldehyde and glycol acetals by 732#strong acidic ion exchange resin are studied.

研究了苯甲醛与乙二醇在732#强酸性阳离子交换树脂催化下的合成条件，得到了缩醛化反应的最佳合成条件：醛/醇摩尔比为1∶1。

According to the results of the former study in our laboratory, trans-1, 2-cyclohexanediol is produced with a lot of acids and water, for extraction of trans-1, 2-cyclohexanediol from the solution, ethyl acetate and butyl acetate were used as extraction reagents, the solubility data of the trans-1, 2-cyclohexanediol in corresponding mixed solvents of some sorts of acetates and water are needed.

根据本实验室前期研究结果可知，反式-1，2-环己二醇是在酸性和大量水存在的条件下得到的，为了把反式-1，2-环己二醇从反应液中萃取出来，本工艺所采用的萃取剂是乙酸乙酯和乙酸丁酯，需要获得反式-1，2-环己二醇在这些酯类与水混合溶剂中的溶解度数据，因而对反式-1，2-环己二醇进行相关固液相平衡的研究是非常迫切和必要的。

Eosinophils and basophils are two additional types of white cells whose roles are to participate in allergic reactions.

嗜酸性粒细胞及嗜碱性粒细胞是另外两种白细胞，它们的工作是参与过敏反应。

Eosinophils and basophils are two additional types of white cells whose roles are to participate in allergic reactions.

嗜酸性粒细胞及嗜碱性粒细胞是另外两种白细胞，它们的作用是参与过敏反应。

Dibutyl succinate was synthesized catalyzed by a strong acid cation exchange resin from succinic acid and n-butyl alcohol.

用强酸性阳离子交换树脂催化丁二酸和正丁醇的酯化反应，合成了丁二酸二丁酯。

The polymerization of conjugated dienes on a cationic exchange resin was investigated.

在一连续的固定床反应器中，采用强酸性阳离子交换树脂催化剂，研究了共轭二烯烃在醚化条件下的反应行为。

Count the total number of cells and eosinophil, peripheral blood Th1/Th2 response, as well as lung tissue examination.

计数细胞总数和嗜酸性细胞，检测外周血Th1/Th2反应，以及肺组织学检查。

And, the frontline orbits theory confirms that NO〓 reacts with nickel and iron sulphides more easily than Fe〓.

热力学分析表明HNO〓比酸性FeCl〓对铜、镍、铁硫化物的反应趋势更大些。

When 100mmol/L 〓 was added into this aqueous system, the solvated electron may react with 〓 to form 〓 free radical, then, the latter oxidized 〓 and generated 〓 at 300nm.

对应于290nm处的衰减在320nm处有一相对缓慢生成过程，该处产物在酸性环境中的生成明显高于中性环境，为〓经脱-OH反应产生的〓。

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。
