二氧化氮

Nitrous oxide pollution of the atmosphere occurs usually from the nitration of cellulose and other organic materials.

大气中的一氧化二氮污染通常由纤维和其他有机物质的硝化作用产生。

The design and Structure of nitrogen tetroxide concentrat ion monitor are introduced.

摘要介绍了四氧化二氮毒气浓度监测仪的设计思路和组成结构。

The lunar lander, on the other hand, was propelled by a mixture of nitrogen tetroxide and Aerozine 50, which doesn't. Its exhaust gases were transparent.

但是，登月舱起飞时的推进力来自于四氧化二氮和Aerozine 50的反应，这种反应不产生火焰，它释放出来的气体是透明的。

Some key points are resolved with advanced software design conception and technology, and a nitrogen tetroxide concentrat ion monitor with sound and light alarm is developed.

通过采用先进的软件设计思想与技术，解决了几个关键问题，成功地研制出了具有声光报警功能的高性能四氧化二氮毒气浓度监测仪。

Objective:To establish the blastchemical combined injury model of nitrogen tetroxide(N 2O 4) explosion,and to investigate the changes in the blood gas of the model.

目的 ：探讨四氧化二氮(N2 O4)和冲击波致冲毒复合伤对动物血气的影响。

Nitrogen tetroxide ; blastchemical combined injury ; blood gas analysis

四氧化二氮；冲毒复合伤；血气分析

Nitrous oxide in the sky can be destructive, but on Earth the substance can be used as a medicine.

在天上一氧化二氮是破坏性的，但是在地面上，它可以被用作一种药物。

Nitrous oxide in the stratosphere is already dangerous for life on our planet, and according to a new study, it may become even more dangerous in the near future.

平流层中的一氧化二氮对地球上的生命而言是危险的。根据一项新的研究，在不久的将来，它可能变得更加危险。

In addition, Yohimbe increases the formation of Nitrous Oxide a natural substance that is important for circulation and sexual performance.

此外， Yohimbe增加形成一氧化二氮（一种天然物质，是非常重要的流通和性的表现。

To understand why nitrous oxide is dangerous, it's important to understand what else is in the stratosphere.

为了了解为什么一氧化二氮如此危险，我们很有必要知道平流层中还有哪些物质。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
