The degree of hydrogenation of a hydrogenated nitrile rubber(HNBR) was determined by a Bromine-Iodometric technique using tricholormethane (CHCI3) as solvent.
采用以三氯甲烷为溶剂的溴碘法测定氢化丁腈橡胶加氢度,研究了反应时间和反应温度对测定结果的影响。
In this paper, the fluorescence decay property of J-aggregates of anionic-cationic cyanine dye, anionic dye and cationic dye adsorbed on the surface of the cubic and tabular AgIBr grains is investigated using femtosecond up-conversion technology.
本研究采用飞秒荧光上转换技术检测了阴阳离子菁染料及对应的阴离子和阳离子菁染料吸附在立方型和T型溴碘化银表面上形成J-聚集体的时间分辨荧光衰减,探讨了增感体系的微观增感动力学机制,并结合对菁染料照相乳剂的光电子行为和照相性能的检测比较了各种菁染料的增感效率大小。
