The results show that stable organic sulfur is the main s9lfur form in ZY coal. Pyrite can be removed under all the atmospheres in the tests, except for nitrogen at 500℃ 1% O2-N2 atmosphere has strong reactivity to remove the stable organic sulfur in ZY coal, especially at 700℃. Under 1% O2-N2 atmosphere, not only a part of stable organic sulfurs can be decomposed, but also more stable organic sulfur-containing structure can be broken down into less stable one.

结果表明，对于ZY煤而言，黄铁矿和不稳定有机硫除在氮气气氛下500℃时热解不能全部分解外，在其他条件下热解时都可以分解。1%氧气对ZY煤中稳定的有机硫的分解有很强的促进作用，不仅可以脱除稳定的有机硫，还可以使更稳定的有机硫断裂生成次稳定的有机硫，在随后的AP-TPR-MS实验过程中，这部分硫在较低的温度下逸出。

The NOx release characteristic of the single coal and blended coals during combustion is studied with tube furnace and one-dimension combustion experiment system, and the coal characteristic and combustion condition which have influence on the NOx emission in the process of pulverized-coal combustion are studied in this paper.

燃烧温度和燃烧区域的气氛对于NOx的生成有很大的影响。保证煤粉稳定燃烧时的最低的O2浓度就是煤粉低NOx燃烧的最佳O2浓度。

The higher performance of reaction and decoking. were obtained in the GOC processes, as compared with their pyrolysis processes.

实验结果表明，O2的存在降低了正癸烷GOC反应的活化能，使反应在较低的温度下具有高的反应性能；O2同时起到消除积炭的作用，提高体系的抗积炭能力。

Methods Thirty rats were randomly divided into three groups: control group, hypoxic hypercapnic group, hypoxic hypercapnia+ligustrazine lig.

将SD大鼠分为正常对照组，4周低O2高CO2组，4周低O2高CO2+川芎嗪组。

The results show that the zinc coating is eroded mostly, and some red rust and black rust appear on the substrate in the environment of oxygen supplied intermittently.

结果表明：在间歇通O2的情况下，锌层大部分被腐蚀，而且在基体上有一些红锈和黑锈产生，镀锌板表面的腐蚀产物呈现着不均匀的针状物；而在间歇通N2时，镀锌板的锌层脱落面积较少，基体上没有产生红锈，腐蚀产物呈大块状；在间歇通O2和通N2的情况下，镀锌板的腐蚀速率先增后降，在200 h时，前者的腐蚀质量损失速率是后者的2倍左右；镀锌板附着库尔勒泥浆时的腐蚀过程受氧去极化过程控制。
