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气、臭、氢、光、酸中碳水合物的保护措施。

In this study, the epoxidation of styrene-isoprene-styr en e triblock copolymers (SIS) by an in situ generated peracid method was discussed .

利用甲酸对热塑弹性体SIS进行环改性,合成了环SIS(ESIS)。
