It was found that the homogeneous orientation tendency of azobenzene was a common phenomenon in the self-assembled films fabricated by electrostatic layer-by-layer dipping process of the side-chain azo polyelectrolytes and poly(diallyldimethyl ammonium chloride); substituents that link to azobenzene have influences on the orientation of azobenzene in self-assembled films,which could be attributed to charge interaction and dipolar interaction between the chromophores and the polycation substrates.

研究表明，侧链型偶氮聚电解质自组装膜中偶氮生色团普遍存在一定程度的沿面取向。偶氮生色团所带端基的类型对其在自组装膜中的取向程度有较大的影响，这主要取决于偶氮生色团与聚阳离子基底的电荷相互作用和极性相互作用等。

Dyeing tests on kraft liner board with domestic liquid cationic direct Yellow DCY-R and direct Brown DCB replacing imported liquid dyes were carried out under laboratory conditions and in the production conditions.

用国产液体阳离子直接黄DCY-R和直接棕DCB染料代替进口液体染料，在实验室条件下和生产条件下对A级牛皮箱纸板进行染色试验。

The coagulating effect of the two proteinases and their mixtureon 7S and 11S was compared. Results indicated that two proteinases interacted witheach other during the coagulating process. 11S gel induced by mixture of twoproteinases was more elastic, and 7S gel induced by separated proteinase was moreelastic.

然后采用SP-sepharose阳离子交换剂从木瓜蛋白酶分离出2种蛋白酶组分，对比它们单独作用和复合作用于7S和11S蛋白的促凝能力，结果表明木瓜蛋白酶中两种组分对7S和11S蛋白的促凝过程中存在协同作用，复合作用可以促使11S蛋白形成弹性更强的凝胶，而单独作用可以促使7S蛋白形成弹性更强的凝胶。

The ion concentrations were studied in both four snow pits on Hami Miaoergou FlatTopped Glacier and one snow pit on Haxilegen Glacier No.51 of Kuitun river in eastern Tianshan Mountain, and both snow pits were retrieved in 2004. The results show that the Ca2+, NO-3 and SO2-4, particularly Ca2+, are major ions in the snow of snow pits in both ablation and accumulation area and also in the ice of snow pits in accumulation area on Hami Miaoergou FlatTopped Glacier, where the relationships among major cation concentrations in snow of snow pits can be revealed by ion concentrations in the ice of snow pits, but the correlation between ion concentrations in the snow of snow pits and elevation is not obvious, which probably can be attributed to the narrow span of elevation and sparse snow pits on glacier. However, the good correlation between ion concentrations in the ice of snow pits and elevation indicates that the elution process weakened gradually with the elevation rise and temperature decrease.

对2004年获取的天山奎屯河哈希勒根51号冰川1个雪坑和哈密庙尔沟平顶冰川4个雪坑的离子浓度特征进行了研究，结果表明：Ca2+、NO-3和SO42-是哈密庙尔沟平顶冰川雪坑雪层和积累区雪坑底部冰中的主要离子（尤其是Ca2+），其雪层中的主要阳离子关系可在底部冰中得以较好的反映，但雪层中各离子浓度与海拔的相关性不明显，可能与海拔的跨度较小和挖取的雪坑较疏有关；雪坑底部冰中的离子浓度与海拔间明显的相关性说明淋融作用随着海拔升高、气温降低而逐渐减弱。
