本文根据稀土元素的原子结构特点，探讨其在陶瓷颜料中的成色机理。并指出研究稀土陶瓷颜料组成结构和发色机理的重要性。
The colouring mechanism of re in ceramic pigments was discussed on the basis of their atomic structures. The importance of studying the composition and chromatic mechanism was showed.
过氧化氢在没有大量减少纸浆产量情况下，具有消除发色基团的良好选择性，所以它在高白度机械浆的生产中是主要的漂白化学品。
Hydrogen peroxide decreases the pulp yield slightly and has the good selectivity to eliminate the chromophores. So it's an important bleaching agent in the high-brightness Mechanical pulp production.
