排放

This paper is focus on the measurement of laminar flame propagation velocity of premixed CH4 with air under two kinds of conditions through the counterflow experimental system.one is with steam catalytic reforming reactions;the other is not.

燃烧系统的各种排放物是空气的主要污染源，城市中的机动车的污染已形成越来越大的威胁。自上世纪70年代末，我国机动车的污染排放量以每年12.7%的速度递增。

With the counterflow diffusion flame serving as an object of investigation and by the use of a detailed elementary reaction kinetics model based numerical analysis method a study was conducted of the influence of thermal radiation on the flame structure and NO x formation in a methane/oxygen enriched (oxygen concentration 60%) air diffusion flame.

在富氧燃烧的研究方面，国内已有一些利用富氧燃烧节能降耗的应用性报道，但是，对富氧燃烧的火焰特性以及污染物的排放等方面的基础特性研究还比较少。

Ammonia gas released by fertilized cropland is a cause of air pollution.

农田中所排放的氨气是导致空气污染的一个原因。

The process and characteristics of heat transfer between cryogenic liquid and water are different under different environment pressure.

不同的排放环境压力下，低温液体与水之间的传热过程及特性会有所不同。

China requires that incinerators discharge no more than one nanogram of dioxin per cubic metre. The European Union sets a standard that is one-tenth of that amount.

中国要求垃圾焚烧炉所排放的二恶英每立方米不超过一毫微克，欧盟的标准则是这一标准的十分之一。

The statistics to which compliance is required, measured in milligrams per cubic metre (mg/m3) of exhaust gas, are in the following table

每个符合的标准都需要统计数字，排放气体以毫克每立方厘米(mg/m3)为单位进行测量，如下表所示

The emission of CH4 and N2O increased basically with acidification cumulation degree.

CH4和N2O的排放基本上随酸化累积程度的加深而增加。

Cupola furnaces account for 70% of cast iron production and generate significant greenhouse gas emissions.

冲天炉占70 ％的铸铁生产，并产生显著的温室气体排放。

The electroplating waste water contains many heavy metals such as chromium,cadmium,nickel,cuprum,zinc.So the direct emission of it will lead to produce great negative effect for ecosystem,human health,industry production and living.

电镀废水中含有的重金属离子如铬、镉、镍、铜、锌等，直接排放将恶化生态系统，给人类的健康和生产生活造成极大的负面影响。

He says the United States needs to take the lead in curbing emissions.

他说美国需要在控制排放上起到带头作用。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
