photochemistry

They are formed byatmospheric photochemistry reaction, and could product OH radical, alkyl radical, ozone,carboxylic acid peroxyacetyl nitrates by atmospheric photochemistry reaction.

羰基合物既是大气反应产物，又能通过反应生成羧酸、羟基自由基、臭和过乙酰硝酸酯。

In this paper, the protection measures of carbohydrate during pulp TCF bleaching, such as oxygen, ozone, peroxide, peracid and photochemistry reaction of bleaching, were respectively.

摘要本文综述了纸气漂白、臭漂白、过氢漂白、催漂白、过酸漂白中碳水合物保护措施。
