同步泵浦飞秒激光锁模理论研究

考虑到饱和增益、饱和吸收、群速弥散和自相位调制等效应对光脉冲的作用,我们给出了一个适用于飞秒脉冲激光系统的锁模方程。并且用这个方程初步地研究了同步泵浦被动锁模的染料激光器。结果表明,染料光脉冲的输出特性将极大地取决于腔内色散、S参数、饱和吸收体的浓度、腔长失谐量等因素。     

聚丙烯/尼龙6挤出原位成纤后的牵引作用

用挤出机共混挤出聚丙烯和尼龙6，加工中尼龙6作为分散相在聚丙烯中形成微纤。改变挤出物挤出模口后所受的牵引作用的速度会产生材料形态与力学性能的变化。发现随牵引速度的提高，尼龙6微纤的平均直径变小，尺寸分布更均匀，力学性能也随之提高。差热分析表明，随牵引速度的增加聚丙烯与尼龙6的相容性略有提高，X-射线衍射分析表明拉伸作用对尼龙纤维晶体中分子链的取向无影响。     

Study on the Synthesis of Metabolite of Clausenamide （CM1）

(-) Clausenamide (1) showed strong nootropic action, while its (+) antipode had no such an action. The content of CM1(2) in the metabolites of (-)1 is much higher than that of (+)11. For comparing the nootropic activity of enantiomers, (+) and (-) CM1 were synthesized. CM1 is the hydroxylated product of the N-methyl group of clausenamide. Oxidation of the C3-OH and C6-OH protected clausenamide to introduce the hydroxyl group into the methyl was tried but unsuccessful. Then de novo s…

STUDY ON THE SYNTHESIS AND PHYSICOCHEMICAL PROPERTIES OF SUCROSE POLYESTER

1. INTRODUCTIONSucrose polyester (SPE) is neither metabolized nor absorbed, it makes no caloric contribution to the diet. Excessive dietary fat intake is associated with increasing risk of obesity, high blood cholesterol, hypertension, coronary heart disease and some types of cancer. At present, fat substitutes are fashionable all over the world. SPE is a new functional fat substitute, which is similar to ordinary oils in physical and chemical properties. In a word, the research and dev…     

非离子表面活性剂存在下光催化降解有机颜料

研究了加入非离子表面活性剂OP-10时有机颜料光催化降解过程,实验选用的颜料为艳红6B(C.I.Pigment Red482),以高压汞灯为光源,TiO2为催化剂.通过改变水溶液的pH值和OP-10的浓度,考察了颜料和OP-10各自的降解特性.实验结果表明,酸性条件下,OP-10的存在明显加快了颜料的降解,碱性条件下反而抑制了颜料的降解.中性条件下,OP-10的增溶对体系的降解有一定影响,浓度为0.126g/L(2.5cmc)时,颜料和OP-10降解效果最好.
