By O2 equilibrium, gel permission chromatography, and autooxidation analyses, we have investigated that the pos itively charge of b82 Lysyl residue is indeed involved in the exhothermic O2 b inding characteristics and somewhat stabilize the tetrameric heme moiety of Hb A.

其纯度以可见光谱和血色素电泳鉴定，并以氧合平衡曲线的测定，胶质层析和氧化速率的分析检视重组血红蛋白之性能。实验结果显示β82Lysyl残基所带的正电性确实影响血红蛋白氧合时的放热反应与其四合体的安定性。

Satisfactory results of numberical calculations usingS - matix variational approach for Cs + O2→Cs++O2- ion - pair formation system have been obtained.

作为上述公式的应用，对Cs+O_2→Cs~++O_2~-反应体系作了数值计算并取得了满意结果。

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。
