二氧化氮

Its coal-burning kilns spew out huge quantities of sooty waste and chemical compounds such as sulfur dioxide and nitrogen dioxide.

烧煤的窑炉喷出大量的黑色废气及二氧化硫和二氧化氮等化合物。

Thedust,acid rain, sulphurous dioxide, nitrogen dioxide, carbondioxide and ozone are the main pollutants.

其中影响最大的是降尘、酸雨、二氧化硫、二氧化氮、二氧化碳和臭氧等。

The results show that there are obvious daily variation of concentrations of O〓、SO〓、SO〓、NO〓. The daily variation characteristic are unlikeness in different season.

结果表明，臭氧，硫酸盐，二氧化硫，二氧化氮等浓度分布有明显的日变化，日变化特征在不同季节有较大的差异。

The experiment obtains the noon peroxy free radical density approximately 11 pptv, the observation had discovered the free radical the density has the direct ratio with the ozonedensity but to have the inverse ratio with the nitrogen dioxide density.

实验测得中午过氧自由基的浓度约11pptv，观测发现自由基的浓度同臭氧浓度成正比而与二氧化氮浓度成反比。

To ensure human body's health, sanitation in driving vehicles crossing the tunnels as well as operation safety of tunnels, the present study take a highway tunnel(620m) as an example, combined with the data analyse of highway tunnel intelligent monitoring system to advance a discharge standard of NO2 concentration in highway tunnels and revelant ventilation solution.

为了保证城市公路隧道行驶机动车内人的健康、卫生和隧道的营运安全，本文以某隧道(620米)工程为例，结合隧道智能监控系统数据的分析，提出了在城市公路隧道内二氧化氮浓度的排放标准，并且提出了相应的通风方案。

The hearing acuity recovered gradually and returned to normal 3 days later: The use of nitrous oxide during anesthesia was incriminated as the possible cause.

该病患之左侧耳听力逐渐恢复，手术三天后恢复正常。二氧化氮的使用为最可能的原因。

The formula for calculating emission strength of carbon monoxide , nitrogen dioxides and hydrocarbons from vehicle fleet on highway are proposed. And the parameter values in the formula are also given.

提出了公路机动车一氧化碳、二氧化氮和碳氢化合物排放强度的计算方法及其各参数的取值范围。

Mukamal and colleagues used meterological and pollutant monitors to measure air temperature, barometric pressure, humidity, and a range of pollutants such as fine particulate matter, black carbon, and nitrogen and sulfur dioxides.

Mukamal和他的同事利用气象和污染物监测来衡量空气温度，气压，湿度以及一系列的污染物如细颗粒物、黑碳、二氧化氮和二氧化硫。

Each subject's average monthly sulfur dioxides, nitrogen dioxide, ozone, carbon monoxide, particulate matter with aerodynamic diameter of less than10μm (PM10) exposure estimates during pregnancy were caculated.

利用2000至2002年的空气品质监测资料，计算研究对象受孕前一个月至分娩期间不同时期的周遭空气中悬浮微粒、二氧化硫、二氧化氮、臭氧、及一氧化碳等污染物的暴露情形。

Such issues are drawing international concern, because Beijing's high levels of carbon monoxide and nitrogen dioxide could cause breathing problems for Olympic athletes.

这些问题引起了全球关注。由于北京空气中的一氧化碳和二氧化氮浓度很高，会给运动员的呼吸系统带来伤害。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
