氟

Objective: To establish a spectrofluorometry for determination of levofloxacin concentration in human cerebrospinal fluid.

目的：建立荧光分光光度法测定人脑脊液中左氧氟沙星浓度的新方法。

Finally, in 1996 CFC production and use was banned altogether.

最后，在1996年，氟氯化碳的生产和使用被取缔了。

However, the CFC's needed for industry are not easily replaced.

然而，工业所需的氯氟化碳并不是容易被替代的。

In addition, CFC's are used in fire extinguishers as well.

此外，氯氟化碳也用于灭火器中。

CFCs are made up of carbon, chlorine and fluorine atoms and there are a number of different types.

氯氟烃是由碳、氯和氟原子构成的具有不同结构的一类化学物质。

Today we know its family of chemicals as chlorofluorocarbons or CFCs.

今天，我们知道它的化学名为氟氯化碳，简写为CFCs。

There were not CFCs before, and now there are CFCs that have been monitored by the people in the atmosphere.

大气中的氟氯烃则是无中生有，已经被人们检测到了。

Each one of us inhales CFCs in every breath we take.

我们每人每呼吸一次就会吸入一些氟氯化碳。

Even though CFCs and nitrous oxide both destroy ozone, they actually work against each other.

即使碳氟化合物和一氧化二氮都会破坏臭氧层，他们彼此间还相互作用。

Although if CFCs were as damaging as they are on Earth, they too might be transienttechnologies.

但是氟氯烃如果在那个星球上同样具有破坏力，那么它同样可能成为短暂的的技术

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
