汽油

The alkylation of isobutane with butene is very important for the production of reformulated gasoline;however,the severe equipment corrosion and environmental hazards are involved in the current alkylation technology.Therefore,some novel alternative technologies are desired.

异丁烷和烯烃烷基化反应对新配方清洁汽油的生产具有重要意义，而目前的烷基化工艺存在严重的设备腐蚀和污染问题，因此亟需新的替代工艺。

"Rare in nature, olefins are obtained by the cracking of petroleum fractions at high temperatures. The simplest ones (ethylene, propylene, butylene, butadiene, and isoprene) are the basis of the petrochemical s industry."

烯烃在自然界很稀少，但在石油裂解成汽油过程中可大量生成，低级的单烯烃已成为庞大的石油化学工业的基础。

"Rare in nature, olefins are obtained by the cracking of petroleum fraction s at high temperatures. The simplest ones (ethylene, propylene, butylene, butadiene, and isoprene) are the basis of the petrochemicals industry."

"My parents decided to donate my car to charity because they didn't want to pay for the insurance and gas anymore," Mr. Chou said."I guess I'll be doing a lot of car-pooling this summer."

"我父母决定将我的车捐给慈善机构，因为他们不想再花钱买保险和汽油，"周先生说，"我想今年夏天我将要多参与拼车一族了。"

The rest of the function of the gasoline carb is not used.

其余的功能汽油碳水化合物是不使用。

The crude carbolic acid was prepared from gasoline alkaline mud by adding sulfuric acid or carbon dioxide.

以炼油厂汽油碱渣为原料，通入硫酸或CO2 中和后去除水相得到粗酚，粗酚经过分馏处理得到馏分在 1 70～ 2 0 0℃的混合酚。

In the UK, the Labour government seems to be heading towards adopting a system of permits – car drivers, for example, would have a carbon credit card which they would have to produce every time they bought petrol.

在英国，工党政府似乎正朝着采用一种许可制的方向发展。例如，驾车人必须携带一种二氧化碳信用卡，每次购买汽油时都必须出示它。

The wheel inside the lighter is made from strong carborundum.

打火机里装着的汽油或丁烷气，也很容易「冒火」，打火机的转轮是用坚硬的金刚沙装成的，当你用它去撞击，摩擦打火石时，一方面因为摩擦发热；另一方面也从打火石上擦下一些铈、镧的粉末，这些灼热的粉末在空气中立即燃烧起来，迸出火星。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
