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.

摘要本文综述了纸浆的氧气、臭氧、氧氢、光催、氧酸合物的保护措施。

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

羰基合物既是大气光学反应的产物，又能通光学反应生成羧酸、羟基自由基、臭氧和氧乙酰硝酸酯。
