3·Application: Suitable designed for usage in fuel hose where resist to gasoline, diesel and alcohol-enhanced fuels. low gas permeability allowed the hose for other gas tight application.

6·This has made it much easier and cheaper to extract gas from shale, coal and other less permeable geological formations (which yield so-called “tight gas”).

通过这种方法，从叶岩、煤炭以及其他渗透性差的地质构造中提取的天然气，更容易也更便宜。

7·Nor is shale gas the only new sort of reserve: tight gas in sandstones and coal-bed methane (the sort of gas that used to kill canaries down mines) are also promising.

不是只有页岩气是一种新的储备能源：在砂岩中的“致密地层天然气”还有在煤层里的甲烷(一种能在矿井里杀死金丝鸟的气体)也十分有前景。

8·The central questions facing renewables now, experts say, are how long credit will be tight and how low oil and natural gas prices will fall.

专家认为，可再生能源现在面临的首要问题是信贷紧缩会持续多长时间，原油和天然气价格会跌到什么程度。
