查询词典 nitro-cotton

The volatile solvent crystallization of 3-nitro-1, 2, 4-triazol-5-one on glass substrate was studied. The observed phenomena verify that the crystal morphologies change from fractal to cube-shaped structure due to the initial concentration increasing, and it can be explained with diffusion limited aggregation theory.

用扫描电镜研究了3-硝基－1，2，4-三唑－5-酮溶液在玻璃基片上挥发结晶行为，观察到随着NTO溶液的初始浓度升高，其晶体形貌从分形结构转变为立方状结构，并用扩散受限模型解释这一现象。

The o-aminobenzaldehyde ethylene acetals can be synthesized from corresponding o-nitrobenzaldehyde by reducing the nitro-group after the protection of carbonyl by ethylene. 2-Aminophenyl ketone ethylene ketal can also be prepared from 2-nitrophenyl ketones by this method.

邻氨基苯甲醛乙二醇缩醛可以由含不同取代基的邻硝基苯甲醛经羰基以乙二醇缩醛保护后还原硝基得到，邻氨基芳香酮乙二醇缩酮可以同样的方法由邻硝基芳香酮得到。

In fact, the blow of a hammer on a few drops of nitro-glycerine, spreadout on a hard surface, was enough to create an explosion.

事实上，只要把少量的硝化甘油滴在坚硬的石头上，用锤子一击，马上就可以爆炸了。

Moreover, we substituted potassium carbonate and Raney Ni for some expensive reagents. We made progress in the basic work of synthesization of ethyl pyruvate p-nitro-phenylthydrazone and indol. Through above improvement, the simple and convenient process with lower costs make it appropriate to be used in the industrial production.

在实验过程中，我们改进了羧酸与仲胺的缩合条件，使产率可达到90％以上，用碳酸钾和Raney Ni或Pd／C代替了昂贵的进口试剂的使用，改进了合成苯腙和吲哚的后处理方法，使整个合成路线的收率提高，成本降低，操作简单，更适合工业化的要求。
