1·For instance, there could be a number of innocuous reasons a higher concentration of hydrogen peroxide is found in the air.
例如，很多其他的原因会引起空气中高浓度过氧化氢。
2·In synthesizing process, the optimum quanta of hydrogen peroxide solution and glacial acetic acid which affect epoxide number were determined.
对合成过程中影响环氧值的两个重要条件：即双氧水和冰醋酸的用量做了大量实验，确定了最佳条件。
3·Then ozonic-hydrogen peroxide bleaching were carried out and the results show that the higher of Kappa number, the poor of the delignification selectivity and the lower of brightness rising.
然后经过臭氧-过氧化氢漂白，结果表明：卡伯值越高，脱木质素选择性越差，白度上升值越低。
