Results show that intramolecular hydrogen transfer is not favored in view of the energy trend along IHT coordinate in the region such as hypericin's peri region, where two hydrogens of hydroxyl groups bond with a common oxygen of carbonyl group and exists two IHBs in the peri region. However, intramolecular proton transfer often occur in the molecule with hexahydric cycle hydrogen bond, where only one pair of adjacent hydroxyl group and carbonyl group.

此外选择设计了一个具有三个分子内氢键的体系，兼具金丝桃蒽酮和其他苝醌类光敏剂的分子内氢键特点，研究表明两个羟基氢与共同的羰基氧形成的氢键由于存在较高的势垒，很难发生分子内氢传递，即具有金丝桃蒽酮端位结构的分子其分子内氢传递很难发生，而一般的能形成六元环状结构的分子内氢键体系容易发生分子内氢传递。

Two different fading procedures were studied. One is the oxidation procedure on polyester fibers,the other is the reduction procedure on wool fibers.The study of oxidation procedure mainly focused on 11 disperse azo dyes and 11 disperse anthraquinone dyes. The study of reduction procedure mainly focused on 7 pyrazolone coupled acid azo dyes and 10 azo disperse dyes which has sulfonic group on the couple component.

本论文研究了11支偶氮型分散染料，11支蒽醌型分散染料在聚酯纤维上的分子结构与光牢度的定量关系，同时研究了7支以吡唑啉酮为偶合组份的偶氮型酸性染料和10支偶合组份上带有磺酸基的偶氮型酸性染料在羊毛纤维上的分子结构与光牢度的定量关系。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
