这种正式名为一氧化二氮的气体对臭氧层所构成的威胁，可能很快就会超过氟氯烃(CFC)化学品。而后者自上世纪八十年代以来就已被限制使用。
The gas, properly known as nitrous oxide, could soon pose a bigger threat to ozone than CFC chemicals, the use of which has been restricted since the 1980s.
最后，炼油厂排放很多的气体，如二氧化硫(SO2)、二氧化氮(NO2)、二氧化碳、一氧化碳、甲烷、双环氧乙烷、氟化氢、氯、苯和其他气体。
Finally, refineries emit many gases like sulphur dioxide (SO2), nitrogen oxide (NO2), carbon dioxide, carbon monoxide, methane, dioxins, hydrogen fluoride, chlorine, benzene and others.
它还可以防止一氧化碳，烟雾，氰化氢，二氧化硫，其他气体，颗粒，烟雾，烟尘，氨，氯，磷，和辐射热的危害。
It also protects against carbon monoxide, smoke, hydrogen cyanide, sulfur dioxide, other gases, particulates, fumes, soot, ammonia, chlorine, phosphine, and radiant heat.
在二氯甲烷溶液中，一氧化氮导致2,3 -环氧酮发生顺式开环反应，生成的顺式羟基硝酸酯化合物为主要产物。
Ring opening reaction of 2, 3-epoxy ketones with nitric oxide in dichloromethane occurred in a syn-selective fashion, producing syn-2-hydroxy nitrates as main products.
