CFCs

The source of much of this chlorine is chlorofluorocarbons (CFCs) that were widely used in many products over the last century.

氯的来源是来自于含氯氟烃，这个物质我们在上个世纪中用于多种产品里面。

Many countries are trying to stop the production of CFCs and to find other chemicals to do the same thing.

许多国家正准备停止生产CFCs，用其它的化学品来替代。

Many scientists are worried that the ozone layer is being destroyed by the CFCs which are used in refrigerators and freezers.

许多科学家担心臭氧层正遭到冰箱和冰库中使用的CFCs的破坏。

Such substances contain the ozone-depleting chemicals bromine and chlorine, and include CFCs and hydrochlorofluorocarbons (HCFCs).

这些物质包含破坏臭氧层的化学元素溴和氯，例如氢氯氟碳化合物（hydrochlorofluorocarbons，HCFCs）和氯氟烃。

Some of the most destructive chlorine source gases are human-made chlorofluorocarbons (CFCs).

某些最有害的氯源气体是人类制造的氟氯化碳（chlorofluorocarbons，CFCs）。

Do not buy hamburgers or pizzas in plastic boxes which contain CFCs .

不要买用带有塑料薄膜制成的包装盒的汉堡或披萨。

however, their long atmospheric lifetimes determine that some concentration of the cfcs will remain in the atmosphere for over 100 years.

然而，它们的长期大气寿命确定一些含氯氟烃在大气中的浓度将继续超过100年。

Like CFCs, they are produced by a smallish number of industrial processes, and cutting emissions of them is cheap and easy.

与氟利昂一样，它们由为数不多的工业过程产生，且[减排成本]低廉又[操作]容易。

Although CFCs are extremely potent greenhouse gases , they exist in only very small quantities in the atmosphere .

虽然氟利昂是最厉害的温室气体，但它们在大气中的含量非常少。

Once in the upper atmosphere, CFCs break down into chlorine atoms, which, when activated by sunlight, destroy ozone molecules.

在上层大气中，氯氟烃一旦在阳光的作用下分解成氯原子，将会破坏臭氧分子。

By 2010, close to 100 ozone-depleting substances, including CFCs, will have been phased out globally.

至2010年，包括氯氟烃在内的近100种消耗臭氧的物质将在全球范围内被淘汰。

The new air conditioner is getting into the air, a small amount of CFCs has been sealed.

新的空调已经进入到空气，少量的氯氟化碳已被查封。

The Montreal Protocol and subsequent amendments have made a major dent in the problem by banning the use of most CFCs.

《蒙特利尔议定书》及后来的修正案通过禁止绝大多数含氟氯化碳物品的使用，大大地缓和了这一问题。

their creation was in 1928 and since then concentrations of cfcs in the atmosphere have been rising.

其创作于1928年，此后的氟氯化碳在大气中的浓度已上升。

CFCs were taken as an example to illustrate that there was not a neutralism for the value of science and technology themselves.

本文以氟利昂为例，对科学技术本身并不具有价值中立性进行了论述。

CFCs are greenhouse, as well as ozone-depleting, gases.

氟利昂是温室气体，也会破坏臭氧层。

Yet the Clean Air Act will heavily tax, and eventually ban, all CFCs and related chemicals.

然而清洁空气法案对所有氟氯碳化物以及相关化学物都课以重税并将最终禁止。

Production of ozone-depleting CFCs was banned by developed nations in 1996, in accordance with the 1987 Montreal Protocol.

生产消耗臭氧层的氯氟烃是禁止发达国家在1996年，按照1987年的蒙特利尔议定书。

Therefore, this MDAC can reduce capacitor mismatching error by CFCS and fulfill the requirement of 12-bit 100MSPS pipelined ADC.

研究结果表明，本MDAC能通过CFCS技术抑制电容失配误差，并达到了12位100MSPS流水线ADC的指标要求。

There is still a black market in CFCs, and halon production has increased in countries such as Brazil, India and Mexico.

现在含氯氟烃还存在着黑市交易。在巴西、印度和墨西哥等国家，卤烃的生产依旧有增无减。
