臭氧

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。

When the target organic was formic acid (a promoter of radical reaction in ozonation), a radical initiation reaction could obviously enhance the ozoantion efficiency.

当目标有机物是对链反应具有促进作用的甲酸时，自由基引发反应可以明显提高甲酸的臭氧化效率。

We have used GC to follow up the formation of epoxy acid and established the acidify condition; we have done series of parallel experiments to better the pivotal condensation reaction between acid and amine; In the cyclization step, we use cheap and available reagent-Lithium amide , rather than expensive LiHMDS, to proceed the reaction; and at last, we introduced green reagent-ozone to clear the phenyl group of nitrogen to avoid using heavy metal reagent-CAN. The total yield for this method is 29.8%.

通过GC监测，确定环氧酸的最佳酸化条件；对关键的酸和胺的缩合步骤，平行试验了多种条件；在环合一步，用价廉易得的氨基锂及催化量的HMDS代替昂贵的LiHMDS进行反应；氮上苯基的脱除采用臭氧，避免了重金属试剂-硝酸铈铵的使用，总收率为29.8％。

There's a lot I want to say about Captain Ozone and his experimental forms of environmental activism.

The nerve root adumbration disintered completely after O3 injection,submerging sign disappeared about 28%,most nerve root disintered,submerging sign partly disappeared about 50%,no nerve root disinter about 22%.

臭氧注射后神经根轮廓全部显露，淹没征消失占28%；神经根大部分显露，淹没征部分消失占50%；神经根显露不明占22%。

The experiments of purification of Taihu Lake water through biological aerated filter, flotation, ozone and biological activated carbon were conducted.

采用曝气生物滤池、气浮和臭氧生物活性炭联用技术对太湖原水进行试验。

The use of chemical disinfectants for disinfection when no one should be carried out under conditions to effect a timely manner after the time window to open the door for ventilation.

使用化学消毒剂进行消毒时，任何人都不应进行的条件下实施后，及时的时间窗开门通风。5 。从实验室也无法确认的作用，臭氧消毒

In general, however, critics agree with Ainsworth's conclusion that new varieties of rice, bred to tolerate high ozone and increased temperatures, are urgently needed.

尽管如此，在总体上，批评家门还是赞成安斯沃思的结论的。那就是，培育能够抵抗高浓度的臭氧和高温的新型而又多样的大米是目前迫切的需要。

BAC filter following ozone contacting column has a better performance than that following air contacting column.

臭氧后生物活性炭柱的运行效果略好于空气后生物活性炭柱。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
