例子在离子层的这地球和其他行星，星体，气体排出物供各种各样设备和过程使用，以及在边缘地区的熔化等离子。
Examples are ionospheres of the Earth and other planets, stellar atmospheres, gaseous discharges for use in various devices and processes, and fusion plasmas in the edge region.
像HFC-134a（化学名称为:1，1，1，2——四氟乙烷）之类的却非如此角色。这种各工业所使用的气体的排放物致使全球变暖的程度比起二氧化碳的要高出1000多倍，大量排出则造成大量污染。
The same is not true for, say, HFC-134a, a gas with various industrial uses that delivers more than 1,000 times more warming than carbon dioxide, mass for mass.
由于这种涂层是一种水基系统，因此，几乎没有刺激性气味，并且不含有可能污染环境的易燃有机化合物，此外，在固化和操作处理过程中没有污染气体的排出。
Since it is a water based system, it has minimal odour and contains no volatile organic compounds that may affect the environment. No outgassing will occur upon curing or during operation.
