Hydrodesulphurization technology could effectively decrease sulfur content in gasoline and octane number loss. 加氢脱硫技术能够有效降低汽油硫含量,减少辛烷值损失。
What with pre-nuptial arrangements, palimony, child custody, we have become accustomed to the short-lived, high octane relationships on which glossy magazines feed. 婚前筹备,生活费,孩子的抚养权——对于这些八卦杂志热衷的短暂而充斥着火药味的关系,我们逐渐习以为常。
Octane is a hydrocarbon and an alkane with the chemical formula C8H18, and the condensed structural formula CH3(CH2)6CH3. Octane has many structural isomers that differ by the amount and location of branching in the carbon chain. One of these isomers, 2,2,4-trimethylpentane (isooctane) is used as one of the standard values in the octane rating scale.
