NF3具有相对短的大气寿命（740年），比C2F6和CF4。更容易分解。HF最终扩散到大气中，在大气中它通过湿沉积被除去。
NF3 has a relatively short atmospheric lifetime (740 years) and dissociates more readily than C2F6 and CF4. HF ultimately diffuses down to the troposphere where it is removed by wet deposition.
虽然它作为自由气体在大气中的寿命比二氧化碳要短的多，但要说吸热能力，它比后者强23倍。
Although its lifetime in the atmosphere as a free gas is much shorter than CO2, it is 23 times more potent in terms of its heat trapping ability.
这是因为黑碳在大气中滞留1至4周，而二氧化碳的寿命为数百年乃至数千年。
That is because black carbon lingers in the atmosphere for one to four weeks, compared to CO2's lifetime of centuries to millennia.
氯原子可以减少大气中汞气体以及温室气体如甲烷的寿命。
Chlorine atoms can reduce the lifetime of atmospheric mercury gas, as well as greenhouse gases such as methane.
二氧化碳一旦被释放出来，就会留在大气层中，在一个世纪左右都会持续产生温室效应，但工业设施的使用寿命才有几十年。
Carbon dioxide, once released, stays in the atmosphere and continues to have a warming effect for about a century, and industrial infrastructure is built to have a useful life of several decades.
问题是，这些气体在大气层中有很长的寿命，可以存留几十年的时间，其中有一些物质甚至可以存留100多年的时间。
The problem is that these gases have a long lifetime in the atmosphere. They stay for decades.
问题是，这些气体在大气中有很长时间的寿命。
The problem is that these gases have a long life time in the atmosphere.
此外，该憎水剂能渗透到墙内一定深度，因而受紫外线照射及大气老化影响较小，使用寿命长。
In addition, the abomination agent can permeate a wall inside certain depth, thus subject to ultraviolet irradiation and atmospheric aging less influence and long service life.
