In the chapter 2 of this dissertation, we studied the cross-coupling reaction of aryl halides and vinyl iodides with sodium azide under the catalysis of copper and amino acids.

在4-碘茴香醚与叠氮化钠的模型反应中，我们考察了不同溶剂、氨基酸、碱、铜盐对反应的影响，最后筛选出了最佳的反应条件：CuⅠ/脯氨酸/NaOH/DMSO。

You must know how to CURE A SLICE OR A HOOK , how to PREVENT A REVERSE WEIGHT SHIFT , how to G AIN HEIGHT and ACHIEVE BACKSPIN.

你必须知道如何治理一片或一个钩子，如何防止反向重量转移，如何与g 氮化铝的高度和实现逆向。

It presents historical demand data (1997, 2002, 2007) and forecasts for 2012 and 2017 by type (e.g., alumina, titanate, ferrite, zirconate, silicon carbide, cordierite, beryllia, silicon nitride), product (e.g., monolithics, coatings, matrix composites), process and market (e.g., electronic, electrical, industrial, transportation, chemicals and plastics, pollution control).

提供了该行业的历史需求数据（ 1997年， 2002年和2007年），并根据类型（例如，氧化铝，钛，铁，锆，碳化硅，堇青石，铍，氮化硅），产品，加工及应用市场（例如，电子，电力，工业，交通运输，化工和塑料，污染控制）预测了2012年和2017年的市场。

Therefore, how to control the intermediate compound is the key to realize BN selective synthesis.

因此，对中间态物种的调控将是实现氮化硼选相合成的关键。

Considering these, it is the first time for us to explore the formation mechanism of BN in benzene-thermal condition.

本文正是在这种背景下，对溶剂热合成氮化硼的反应机理进行了开创性的探索。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
