The test results showed that under low ambient temperature and aphotic storage conditions jet fuel exhibited good color stability.Oxidation reactions,such as photo-catalyzed oxidation and radical oxidation,were the main reaction mechanism of color degradation,and copper played an important role in catalyzing the oxidation reactions.Under static thermal stability testing condi...

试验结果表明，喷气燃料在较低温度、无光储存条件下具有很好的颜色安定性；氧化反应是导致喷气燃料颜色变深的主要反应机理；静态热安定性试验条件下，喷气燃料的颜色随氧化时间呈相对稳定的加深趋势；氧化铝吸附脱除了喷气燃料中的一些原有氧化抑制剂，使喷气燃料在较高温度、有氧条件下易于发生氧化反应；铜在喷气燃料氧化变色反应过程中具有明显的催化作用。

Transition metal Pyrazolyl ligands have attracted considerable attention as in catalysis, magnetic coupling, biological mimicry, electron transfer, optic-physics area because of pyrazolyl ligands have luxuriant self-assembly chemistry and as a kind of multifunctional organic ligand.

吡唑类配体是一种较复杂的多功能有机配体，有着丰富的自组装化学，使其形成的过渡金属配合物在催化、生物仿生、磁学耦合、电子转移和光物理性质等方面具有潜在的应用价值，近年来受到广泛的关注。

The experimental results denoted that the finer pearlite along the austenite boundaries in the as-cast Cr30Ni20NRE steel disappeared first under long-term and high-temperature service condition, and that an umber of Cr- richened carbides were formed due to unila-teral carburizing at long-term and high- temperature, consequently causing Ni to concentrate, bulging and calalyzing decomposition of the carburizing gas.

试验结果表明，长期在高温条件下服役，铸态Cr30Ni20NRE耐热钢中沿奥氏体晶界的珠光首先融入奥氏体，长期高温单边渗碳形成大量富铬碳化物，促使镍富集并起泡形成瘤状物，催化含碳气体的分解；表层瘤状物使辐射管表层疏松，表面积扩张，加快了碳向基体的渗入，提供了碳化物持续长大的条件，并引起沿碳化物周边开裂和奥氏体基体严重萎缩；合金元素的重新分布造成主合金元素铬和镍产生两极分化，镍和硅的富集促使石墨化，与侵入的氧形成内部氧化空洞和膨胀疏松，最终导致构件穿孔失效。

Nanocrystalline hexagonal VSi〓, with an average diameter of 35nm, was prepared via a reduction-silication route by the reaction of metallic sodium with vanadium tetrachloride and silicon at 650℃ in a molten salt system of magnesium chloride and sodium chloride. The sample had good oxidation resistance at 1000℃.

金属硅化物通常具有很高的熔点、较低的电阻率、很好的高温热稳定性，有些还具有奇异的光、电、磁、超导、催化等性能，因此是一类最富潜力的高温结构材料和电子材料。

For ozonolysis, the SOA yield has not been changed by inorganic seed aerosol, because the products are mainly carboxylic acids, which has much lower saturation vapor pressure and thus easily undergo homogeneous nucleation or gas-particle partitioning to be in the aerosol phase.

而对于α-蒎烯臭氧氧化的过程，实验结果表明，干态硫酸铵颗粒物种子的存在对SOA产率无影响，对臭氧氧化生成的SOA分子鉴别的结果表明，可鉴别组分中有很高比例的有机羧酸类物质，这一比例远高于光氧化产物，这些有机酸具有较低的挥发性而极易形成颗粒相，并且不参与异相酸催化反应。

In the United States, chronic alcoholism and hepatitis C are the most common ones.
