Bonding structure and the change of chemical composition at the Cu/ceramic interface are investigated systematically with microanalysis. Furthermore, it is observed that copper bonding to Al〓O〓 ceramic is formed by chemical reaction between Cu〓O within the Cu-Cu〓O eutectic and Al〓O〓 at high temperature, CuAlO〓 as a reaction result is produced, mechanic join and physical osmose are not the main factor.

运用多种显微分析技术，对铜-陶瓷键合界面的微观结构，以及键合前后物相化学成份的变化，进行了系统的研究，在此基础上，明确了Cu-Al〓O〓陶瓷的键合机理；机械交联和物理渗透不是形成键合的首要因素，键合是通过Cu-Cu〓O共晶熔体中的Cu〓O相在高温下与Al〓O〓陶瓷发生了化学反应，形成了牢固的化学键合，同时伴随有一些CuAlO〓物相的生成。

The results of simulating multi-stage H〓O〓 displacement bleaching showed that the brightness of bleached pulp increased along with the increase of H〓O〓 concentration in fresh bleach liquor.

多段H〓O〓置换漂白的模拟试验结果表明，漂后浆白度随新鲜漂液H〓O〓浓度的提高而提高，但在相同的新鲜漂液H〓O〓浓度下，不同漂液量时的漂后浆白度基本相同。H〓O〓消耗量随新鲜漂液H〓O〓浓度和漂液量的下降而下降，漂白效率的变化恰与H〓O〓消耗量的变化相反。
