But ethanol does not pack a particularly powerful punch. It is also susceptible to absorbing water, further diluting its oomph. It takes days to ferment the stuff.
但是乙醇不会聚合起它的强力；乙醇能与水相溶，因此就会稀释它的效用；而将乙醇拿来发酵也需要花费好多天。
Congress eliminated tax credits for solar energy, ethanol could not compete with cheap gasoline and a wind farm boomlet in California failed to catch on in the rest of the country.

The electrification of cars, however the electricity might be generated, would be the end of the road for ethanol. But not necessarily for drop-ins.
尽管汽车电动化所使用的电可能也要制造出来，但是它将终结乙醇在交通中的使用，但是却不一定终结完全替代型生物燃料。
The resulting biofuel is not only energy-rich and water repellent but it also has a higher boiling point than ethanol.
最终的生物燃料不仅要是一种高能量的水不溶物，而且沸点也要高于乙醇。
Tariffs that block Brazilian ethanol from northern markets do not apply to drop-in hydrocarbons.
阻挡巴西乙醇进军北美市场的关税并不适用与完全替代型碳氢化合物。
What, then, is the most abundant feedstock for making ethanol which does not wreak havoc on food supplies, is environmentally friendly, economic and has all the enabling technologies in place?
那么，能够大量用于生产乙醇又不影响食物供应、环保、经济并且有所有可行技术的原料是什么呢？
Turning the food crop into ethanol would not be the best use of the energy embedded in the kernels' carbohydrates, according to a new study in Science.
据刊登在科学在线的最新研究，农作物所含的碳水化合物中蕴涵着能源，但以农作物为原料生产生物酒精并不是利用它们的最好方法。
Exactly how alcohol protects the injured is still not clear. But a past study on animals did find that ethanol protected against nerve damage.
酒精是如何保护伤者的，其作用细节尚不清楚，不过之前的一项动物实验已经得出了乙醇能够防止神经受损的结论。
But it's not easy to produce isobutanol with the help of microbes like the ones that ferment those sugars into ethanol.
但是，异丁醇并不能像乙醇那样可以由微生物发酵糖分轻易制得。
Surprisingly, they also passed up the opportunity to lavish more subsidies on ethanol. They did not even bother to consider a carbon tax or a cap-and-trade scheme for greenhouse gases.
令人惊讶的是，他们也放弃了狂补酒精燃料的机会，就连征收碳税或者是控制温室气体的总量管制计划，他们都懒得考虑。
Researchers suggest redefining the thresholds for specific biomarkers to reduce the chances of false positive tests among people who did not consume alcohol but were exposed to ethanol in other forms.
研究者建议重新规定生物信号的阈值，以减少造成假阳性的机会，假阳性通常出现在未饮用酒精饮料但却接触了其它形式的酒精的人们中间。
There was just an agreement in the U.S. Congress to cut not only the ethanol tariff, but the ethanol subsidy.
美国国会也就取消乙醇进口关税和取消乙醇补贴达成了协议。
The genetic modification does not appear to weaken the plants, and the transformation may have turned them into more efficient sources of ethanol.
基因改造并没有使植物变弱，这一转化可以使其变为乙醇生产中更有效的原料。
Although the glass shape did not affect the concentration of ethanol vapor, the temperature did, with chilled champagne releasing less ethanol, but the same amount of carbon dioxide.
虽然酒杯的形状并不影响乙醇蒸气的浓度，但对于释放少量乙醇的冰镇香槟而言，酒杯形状却能对相同数量的二氧化碳产生影响。
So, since we can produce ethanol from the plant parts that are not eaten, the amount of animals feed that is available will not be reduced.
所以，鉴于我们是使用家畜不食用的部分来制造乙醇燃料的，那么家畜可使用的饲料不会减少。
The above-mentioned group of chemical substances do not dissolve in alcohol, only one of which dissolves in ethanol.
上面提到的一组化学物质除一种可溶于乙醇外，其余都不溶于醇。
Characters: White crystalline powder, soluble in water, dilute alcohol, liquid ammonia and dimethylformamide, and not soluble in ethanol, ether and acetone.
