Experimental results in systems with the presence and absence of sulfamic acid as a suppressor of nitrous acid are obtained.

对比了加入氨磺酸条件下的实验结果。

As [HNO3] 1.0M,φ decreases with the increase of nitric acid concentration because of the formation of nitrous acid.

当HNO_3浓度大于1.0M时，φ的下降与体系中形成HNO_2有关。

The quantity of nitrous acid is proportional to the power of light and concentration of uranyl nitrate and decreases with the increase of concentration of nitric acid at higher acidity.

亚硝酸的生成量与光照功率和U的浓度成正比，当酸度大于0.1mol/l时，其量随酸度增加而减少。

The oxidation of mono-methylhydrazinewith nitrous acid in nitric acid medium was researched.

采用分光光度法研究硝酸介质中单甲基肼与亚硝酸(HNO_2)的反应。

Sphaeroides (108 no./ml) were added in five different concentrations of Nitrous acid in water to study the removal of Nitrous acid after 24 hours.

ml於24小时后，水中亚硝酸盐去除率达100%，另外光合菌在五种不同铵氮浓度下，光合菌菌量於108 no。

At the same time, the enthalpy change of 212 kJ/mol for Tempo trapping methyl radical, namely O-〓 bond dissociation energy has been also obtained. This value is close to that of nitrous acid ester and far less than that of nitric acid ester. It is probably due to the relatively strong electron withdrawing capability of nitryl group.

同时我们还测得了甲基自由基与Tempo的反应的焓变，即O—〓键离解能为212 kJ／mol，它接近于亚硝酸甲酯中C—O键的离解能，而小于硝酸甲酯中的键离解能，这可能和硝酸根的吸电子能力较大有关。

One was that one molecule of nitrous acid di-rectly reacted with DMA,and the other was that two molecules of nitrous acid reacted first to yield nitrogen trioxide,which then reacted with DMA.

计算结果表明，DMA与亚硝酸间接反应的活化能比直接反应的低约55kJ/mol，由此可推断DMA与亚硝酸生成NDMA的反应是以两分子的亚硝酸先生成ONNO2再亚硝化DMA为主要反应途径。

Test Preparation Transfer about 2 g of the substance under test, accurately weighed, to a glass-stoppered, 250-mL conical flask, add 20 mL of a mixture of equal volumes of nitric acid and sulfuric acid, attach a suitable condenser, reflux the mixture for 1 hour, cool, cautiously dilute with water, and boil until fumes of nitrous acid no longer are noticeable.

Test准备 Transfer大约2 g在测试之下的物质，准确地被称，对玻璃防止， 250ml conical烧瓶，增加硝酸的相等的容量混合物的20 mL，并且硫酸，附有一适当的 condenser，循环加热混合物1个小时，凉快，慎重地稀释与直到亚硝酸发烟的水和煮沸 acid不再是引人注目的。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.
