乙炔

Someone knowledgeable in handling acetylene fires should be left in charge.

在应付乙炔起火方面有丰富知识的人留下来负责。

It is because that the particle size of acetylene black is smaller than that of graphite, it is easy to disperse well among active material.

这是因为乙炔黑的粒度比石墨小，比表面积相对更大，能很好地分散在活性物质之间。

Adsorption and desorption of acetylene on HZSM-5 and NaZSM-5 zeolites were investigated in the presence of trace water.

在80℃下，NaZSM-5上乙炔的饱和吸附量约为HZSM-5上的5倍。

After several years of development, in east China has become the biggest oxygen, acetylene tube production base in Jiangxi Province, the largest private-owned manufacturing enterprises.

经过几年的发展，已成为华东地区最大的氧气、乙炔管生产基地，江西省最大的民营独资生产企业。

Cuprous acetylide takes the form of a russet or reddish-brown powder, insoluble in water and in the majority of organic solvents

乙炔亚铜是黄褐色的红棕色的粉末，不溶于水和大多数有机溶剂。

乙炔亚铜是黄褐色的红棕色的粉末，不溶于水和大多数有机溶剂。

It was found that copolymerization of selected acetylenes with different polarity by using palladium acetylide complex catalysts is an effective method for improving solubility of polymers, especially doped polymers, which makes the above mentioned polymers and doped ones a new type of π-conjugated sensing material for preparation of thin film humidity sensor.

研究发现，以新型过渡金属钯-炔配合物为催化剂，通过选择具有不同极性的取代乙炔单体进行共聚，可有效地提高聚合物的溶解性，尤其掺杂聚合物的溶解性，实现可溶酸掺杂，继而开发出上述系列新的π-共轭型聚炔湿敏材料，用以制备薄膜型湿敏元件。

Taking double-layer paracyclophane derivatives, platinum acetylide chromophores, porphyrin derivatives, C60, C70 and octupolar molecule as the example, our research results have been reported.

以双层二聚二甲苯邻甲酸衍生物、铂乙炔化物、卟啉衍生物、C60、C70、八极矩分子为例，报道了我们在这方面的研究结果。

The platinum terpyridyl acetylide complex containing a simple amine group in the acetylide ligand could be utilized as a chemo-sensor for detection of micromolar concentration of protons by monitoring the changes both in luminescence and color.

实验发现： 1.4-N，N-二甲基苯乙炔为辅助配体的三联吡啶Pt络合物TA在质子存在下吸收和发光变化明显，因此可以通过颜色或发光的变化检测微量质子的存在。

The absorption spectra of the terpyridyl platinum acetylide complex containing monoazacrown moiety in the acetylide ligand was blue-shifted upon complexation with metal cations.

对位带有氮杂-15-冠-5冠醚的苯乙炔为辅助配体的三联吡啶Pt络合物TAC在金属离子的存在下吸收光谱的变化明显不同。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
