天然气

Coal, oil, natural gas, and all other fuels are stored energy from the sun.

煤炭，石油，天然气，和其他燃料都是存储的太阳的能量。

We should exploit these energies, such as coal, oil and natural gas.

我们应该开发利用这些能源，如煤、和天然气等。

Various fuels such as coal,gas,oil and food are common examples of chemical energy.

最常见的化学能包括煤、天然气、石油、和食物等各种各样的燃料。

That has involved bigger imports of oil, gas and coal, and so more foreign entanglements.

那会伴随着更大宗的石油、天然气和煤进口，以及更多的国外事务的牵扯。

Britain is the main mineral resources of coal, iron, oil and gas.

英国是主要的矿产资源，煤，铁，石油和天然气。

Moreover, human activities play a more and more important role in the development of tidal flat. The concentrated coastal engineering change the dynamic environment of the tidal flat, and the exploitation of oil, natural gas and groundwater results in surface subsidence in the coastal area. In addition, sea level rise and the accompanied increase of storm surge frequency and intensity, will strengthen the erosional process, reduce the tidal flat area, coarsen the sediment, made the slope steep, and cause other environmental effects.

人类活动的环境效应对渤海潮滩发育的作用越来越明显，环渤海地区密集的海岸工程将改变原始的潮滩动力环境；石油、天然气、地下水的开采会导致海岸带发生地面沉降；海平面上升以及与其相伴随的风暴潮作用频率与强度的增加都将会使渤海潮滩的侵蚀过程加强、潮滩面积缩小、滩面物质粗化、坡度变陡，并产生一系列的相关的环境效应。

The article mostly discusses gas application burning excess air coefficient calculation methods, introduces different calculation formula application range, and giving examples in natural gas, liquefied petroleum gas and manufactured gas calculate its excess air coefficient on the same oxygen content of fuel gas, and the influences of excess air coefficient to air consumption and fuel gas production during burning process.

文章主要论述了燃气具燃烧过剩空气系数的计算方法，介绍了不同过剩空气系数计算公式的使用范围，并举例天然气、液化石油气和人工煤气三气种燃气具在测得烟气中相同氧含量时过剩空气系数的计算方法，以及过剩空气系数对燃气具在燃烧过程中消耗空气量和同时产生烟气量的影响。

On top of that, gas prices have collapsed over the past year.

最重要的是，天然气价格在去年的一年里暴跌。

Experts forecast that the combustible ice is possible to be the new energy for human.

专家预测，"天然气水合物"的"可燃冰"有可能成为人类高效的新能源。

Meanwhile, the hydrogen sulfid content and heavy hydrocarbon content are the most important two subfactors in gas composition factor.

因此，硫在天然气中的溶解机理既包括化学溶解也包括物理溶解，是二者的有机结合。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
