乙醛

During alcoholic fermentation acetal dehyde acts as a hydrogen acceptor instead of oxygen.

在这个过程中乙醛取代了氧作为氢的受体。

But the acetaldehyde of lactococcus strains is about 10μg/ml.

而乳球菌乙醛的平均产量在10μg/ml左右。

Acetaldehyde is an intermediate of alcohol metabolism, but its effect on alcohol dependence is not clear.

乙醛为酒精代谢的中间产物，但其在酒依赖中的作用不清楚。

The results showed that acetaldehyde had important roles in alcohol dependence behavior in mice.

结果表明乙醛在小鼠酒依赖行为中可能存在一定促进作用。

This would promote the decomposition of acetaldehyde has not prematurely enter the kidney.

这将促进乙醛的分解并没有过早地进入肾脏。

Therefore, the United States to join the food, especially acetaldehyde, the right half of the Chinese people are not secure.

所以，美国的食品尤其是加入乙醛的，对一半中国人并不安全。

The energy efficiency of acetaldehyde ozonation increased with the decrease in energy density.

臭氧氧化乙醛的能量效率随能量输入密度的增加而减少。

Another reason for this increasing interest is that formaldehyde and acetaldehyde are more available than propylene.

另一个原因，这越来越感兴趣的是，与比丙烯，甲醛和乙醛更容易利用。

The energy efficiency of acetaldehyde ozonation also increased with the decrease in energy density.

催化臭氧氧化乙醛的能量效率随能量输入密度的增加而减少。

But those with only one copy can develop a tolerance to acetaldehyde and become heavy drinkers.

而那些携带一个拷贝数的人却可以耐受乙醛，从而大量饮酒。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
