胺化

Lactam ring opening.That is to say,the inhibition mechanisms ofβ-lactamase are not yet fully understood.

它们大多只是集中在抑制剂的酰化反应上，而β-内酰胺开环以后的反应，理论研究少之又少。

We argue that the hemispheric asymmetry of iron content may underlie that of the dopaminergic system and may be related to motor lateralization in humans.

我们推测这种不对称性也许反映了左右大脑半球在多巴胺代谢中对铁的不同需求，并和人类的运动偏侧化分布有关。

The CNTs were characterized with the transmission electron microscope and infrared spectroscopy. In addition, the dispersion of the CNTs in water was investigated with the optical microcopy and the viscosity meter. The FTIR spectrum experiments showed that there were many hydroxyl groups and carboxyl groups, on the surface of the acid-treated CNTs.

采用硫酸和硝酸混合酸对催化裂解法制备的多壁碳纳米管进行纯化，然后运用十六烷基三甲基溴化胺对CNTs进行修饰，并利用透射电子显微镜、红外光谱和拉曼光谱表征了CNTs的表面结构；另外，通过数码照相机和乌氏粘度计研究了修饰的CNTs在水中的分散性能。

Sodium borate was chosen as the buffer andα- naphthylamine and NaBH3CN as the derivation agents. The optimal conditions were 60 mM pH 11 sodium borate buffer, 1.0 psi pressure injection for 90s. Compared with the normal CZE method, the detection sensitivity of glucose was enhanced by more than 20 times, and that of fructose nearly 60 times.

本文的最后一部分，选用硼砂作为缓冲液，以α-萘胺及NaBH3CN作为衍生化试剂，探索了采用场放大进样方法，用毛细管电泳对葡萄糖和果糖进行分离和富集的实验条件，最优的实验条件为60 mM，pH 11.0硼砂缓冲液，1.0 psi压力进样90s，和常规方法相比，葡萄糖的检测灵敏度提高了20多倍，果糖提高了近60倍。

The high purity of 2-mercapto-β-naphthothiazole was obtained with α-naphthylamine as raw material via reaction of seal glass tube, alkaline extraction, vapor distillation, acidification of acetic acid and ethanol recrystallization.

以α-萘胺为起始原料，通过封管反应、碱提取、水蒸气蒸馏、乙酸酸化和乙醇重结晶，取得了纯度较高的2-巯基－β-萘并噻唑。

In chapter 4 an abnormal reaction that the nitro group of 1-aryl-2-nitroethenescan be easily replaced by the organic moity of FG-RZnI using Ni〓 and tertiaryamine as catalyst was first given. The experimental results show that in the presenceof catalytic amount of Ni〓 and tertiary amines, the reaction of FG-RZnI andl-aryl-2-nitroethenes give the substitution products l-aryl-l-alkene, instead ofMichael addition products.

通过实验发现，在催化量的Ni〓及叔胺催化下， l-硝基-2-芳基乙烯与烷基碘化锌并不进行Michael加成反应，而是发生1-硝基-2-芳基乙烯中硝基被取代的反应，生成了高产率的1-芳基-l-烯烃，由于此反应的原料易得、反应条件温和、产物的产率高，因而是合成l-芳基-1-烯烃的有效方法。

Microemulsion templates formed by sodium dodecyl sulfate, cetyltrimethyla-mmonium bromide and nonyl phenol polyethyleneoxy ether (Oπ-10),respectively,were used to fabricate CaWO4 nanoparticles with different morphology. The possible reactionmechanism was proposed and explained.

然后，分别利用十六烷基三甲基溴化胺、十二烷基硫酸钠、壬基-酚基-聚乙氧基醚(Oπ-10)形成的微乳液模板合成了具有多种形貌的CaWO4纳米粒子，并对其反应机理提出推测和解释。

In this article, different soft templates formed by sodium bis (2-ethylhexyl) sulf-osuccinate, nonyl phenol polyethyleneoxy ether (Oπ-10) and cetyltrimethyla- mmonium bromide were used to fabricate CaCO3, BaCO3 and CeO2/CuO nanoparticles with different morphology.

本文分别利用丁二酸二(2-乙基己基)酯磺酸钠、壬基-酚基-聚乙氧基醚（Op-10）和十六烷基三甲基溴化胺形成的不同软模板合成了具有不同形貌的CaCO3， BaCO3和CeO2/CuO纳米粒子。

The solvent type significantly affects the catalyst activity and selectivity for cyclohexanone oxime.

结果表明，溶剂的种类对硝基环己烷氢化产物的选择性有很大影响，乙二胺是该反应的合适溶剂。

To study effects of --stepholidine SPD on the phosphorylation of a dopamine- and cAMP-regulated phosphoprotein DARPP-32 in the striatum of oxidopamine-lesioned rats.

目的 研究左旋千金藤立定SPD对羟多巴胺损毁大鼠纹状体中DARPP-32蛋白磷酸化程度的影响。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
