乙炔

Being different from the case of HZSM-5, the species on NaZSM-5 can not be further activated because they are decomposed to acetylene and desorbed with increasing temperature.

在NaZSM-5上，乙炔只通过与Na^＋位上的水作用形成乙烯醇，后者与沸石孔道中的阳离子以静电结合构成弱吸附物种。

Body water content was measured with deuterated water, body composition by dual-energy X-ray absorptiometry and computed tomography, and cardiac output and systemic ascular resistance by acetylene rebreathing technique both before and after therapy.

分别于治疗前后应用重水测量体液量，用双能X线吸收计量法及CT测定身体组成，用乙炔再吸收技术测定心输出量及全身血管阻力。

Our results indicate that the dimerized model is the most stable configuration for both ethylene and acetylene when the converge is 0.5 ML, while the end-bridge configuration becomes the most favorable structure when the converge increases to 1.0 ML.

结果表明：无论是吸附乙炔还是乙烯分子，当覆盖度为0.5 ML时，最为稳定的吸附方式为dimerized模型；当覆盖度增大到1.0 ML时， end-bridge模型为最稳定的吸附方式。

Therefore, the pre-fabricated functional surface containing azide groups can be covalently anchored through click-chemistry by newly designed acetylene-appended HBCs. These HBC derivatives not only possess the potential in the formation of SAM, but their alignment modes of edge-on or face-on could be controlled by tailor-made molecular design.

因此，我们设计出末端带有乙炔官能基之HBC分子，希望在预先处理并带有叠氮(-N3)官能基的基板表面上进行click-chemistry (速配组合式化学、点击化学)，利用共价键之形式将HBC分子镶嵌於基板表面，除了藉此制作出分子自组装单层薄膜之外，利用分子设计进一步控制其排列方式为edge-on或是face-on。

This paper studies the measurement of potassium content in DEB powder of hot battery by using the air-C2H2 flame atom-obsorption spectrum, and i nt roduces the optimum measuring condition and disturbing factor.

研究与运用空气-乙炔(Air-C2H2)火焰原子吸收光谱法测定热电池正极粉中的钾含量。同时介绍了最佳测定条件及呈良好线性范围的浓度，对干扰因素进行了综合考虑。

This paper determined Li+ content of LiFePO4/C composite by air-acetylene flame atomic Absorption spectrum method,recovery rate of standard series sample with Fe2+ and PO3-4 and without Fe2+ and PO3-4 were determinated.

采用空气-乙炔火焰原子吸收法测定了LiFePO4/C复合物中的锂含量，考察了不加基体和加入基体的两种标准系列的回收率；因为目前还没有LiFePO4的标准样品和标准分析方法，所以实验采用模拟标准样品考察了不同酸介质和不同酸用量的影响，并进行了Fe2+、PO34-、Cr3+、Mg2+、Mn2+、Co2+、Ni2+离子对测定锂的干扰实验。

A series of imides oligomers were synthesized with the phenylethynylphthalic anhydride , nadic anhydride and cyanophthalic anhydride as endcapped agents.

我们以苯乙炔苯酐、降冰片烯二酸酐和氰基苯酐为封端剂合成了一系列的酰亚胺低聚物。

The value of r decreased with iodine doping due to the increased interchain coupling.

这也使掺杂后的反式聚乙炔成为链间相互作用微弱的三维体系。

The research on coking during the pyrolysis of coal to acetylene in the plasma (1) In the arc plasma jet, different kind of coal has different coking character. The aromatics, colloids, asphaltene and Carbenes are the precursors of the cokes.(2) The mostly reasons of coking in the plasma reaction equipment are the particle size, the feeding velocity, the power of plasma and the structure of equipment.

五、煤等离子体热解制乙炔装置结焦性研究的结果(1)在电弧等离子体射流的条件下，煤种的结焦能力不同，煤中的芳香分、胶质、沥青质和碳青质是结焦前驱体。

When we used ligand 3k-Zinc in the asymmetric addition of phenylacetylene to ketones at room temperature, the highest ee was up to 85%.

当我们用配体3k-Zinc作为催化剂在对苯乙炔对酮的不对称加成反应中，产物最高的ee可达85％。

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。
