In our work, as a preliminary experiment, the N-phenacylisoquinolinium bromide was reacted with methlhydrazine in refluxed acetic acid. Unexpectedly, 2-methyl-1,2,3-triazole was obtained. The further study of this reaction led to a more simple starting material,α-bromoacetophenone to react with methylhydrazine, obtaining the same product.

我们在研究N-苯乙酰异喹啉溴化物与甲肼在冰醋酸中的反应时，意外地得到了2-甲基-4-苯基-1，2，3-三氮唑，经过进一步的研究发现α-溴代苯乙酮与甲肼也能得到同样的产物。

In addition the company also sell a variety of borides Agents, zirconia grinding ball, lithium-bentonite, silicon nitride iron, Castable superplasticizer used, brick,×, silica and other refractory materials and products .

此外公司还代理销售各种硼化物、氧化锆研磨球、锂基膨润土、氮化硅铁、浇注料用高效减水剂、粘土砖、高铝砖、硅砖等多种耐火材料和制品。

GaN with a thickness of 150~200μm was grown by hydride vapor phase epitaxy.

接著利用氢化物气相磊晶法成长150~200μm的氮化镓厚膜。

Analyses of spectroscopic and crystal structural data of iridium complexesIr(PR3)Cl and the Vaska's complex reveal that NHC ligands and phosphines have a similar donating ability toward Ir metal center.

并且从光谱分析及晶体结构数据发现[Ir(PR3)Cl]的错合物与Vaska's 错合物相当类似。因此，我们推论其含氮杂环碳烯与膦化物在ㄧ价铱金属上有相似的配位能力。

The novel molecular topological index was recommendedrelating to such atomic properties as electronegativity,electron number of valence shell,number of bonding electrons,the main quantum number of valence shell and bond length.

采用该拓扑指数对饱和烷烃、烷基苯、烷氧氯硅烷、卤代苯、含氮杂环化合物、碱金属卤化物及卤化锡的性质/活性进行了相关关系的研究。

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。
