直链烷烃使机器的“爆震”问题更加严重。
The straight - chain alkanes exacerbate the problem of engine " knock ".
公司的酶和细菌能够将蔗糖转为叫做直链烷烃的分子，该类型的分子含有12到16个碳原子。
Codexis's enzymes and bacteria can turn sugar into molecules called straight-chain alkanes which have between 12 and 16 carbon atoms in them.
所以，丁醇释放的能量比同样重量的乙醇多，在特性是它更像直链烷烃分子；它也不像乙醇那么容易吸水。
That gives butanol more energy for a given mass and makes it more alkane-like in its properties; nor does it absorb water as readily as ethanol.
和乙醇一样，丁醇也属于醇类，这说明每一个丁醇分子包括一个氧原子和直链烷烃里的那种碳原子、氢原子。
Like ethanol, butanol is an alcohol. That means each of its molecules contains an oxygen atom as well as the carbon and hydrogen found in an alkane.
Codexis的酶和细菌能够把糖转变为有12到16个碳原子的直链烷烃，这种物质是柴油最主要的组成部分。
Codexis's enzymes and bacteria can turn sugar into molecules called straight-chain alkanes which have between 12 and 16 carbon atoms in them. Such alkanes are the main ingredients of diesel fuel.
GTL产品基本上由直链烷烃、烯烃组成，具有无硫、无氮、无金属、无芳烃等特点，是环境友好的油品和化学品。
The products from GTL include fuel oil, base oil for lubricant, and other chemicals, which are environmentally friendly due to their few S, N, metal, and aromatic hydrocarbon content.
在系统命名法中，直链的、有一个双键的烃可通过将其相应烷烃名字的词尾—ane改换为- ene而得。
Unbranched hydrocarbons having one double bond are named in the IUPAC system by replacing the ending -ane of the alkane name with -ene.
直链的、有一个叁键的烃可通过将其相应烷烃名字的词尾—ane改换为- yne而得。
Unbranched hydrocarbons having one triple bond are named by replacing the ending -ane of the alkane name with -yne.
直链的、有一个叁键的烃可通过将其相应烷烃名字的词尾—ane改换为- yne而得。
Unbranched hydrocarbons having one triple bond are named by replacing the ending -ane of the alkane name with -yne.
