1.They are formed byatmospheric photochemistry reaction, and could product OH radical, alkyl radical, ozone,carboxylic acid peroxyacetyl nitrates by atmospheric photochemistry reaction.
羰基化合物既是大气光化学反应的产物,又能通过光化学反应生成羧、羟基自由基、臭氧过氧乙酯。
2.The function of hydrocarbons and nitrogen oxides in photochemical smog formation and the formative process of ozone and peroxyacetyl nitrate are discussed.
