Study on State of Terbium Ion in Liposome by One order Derivative Fluorescence Quenching Method

The state of Tb3+ is investigated in liposome. When the concentration of PC is below CMC (critical micell concentration), most of Tb3+ is associated with PC, the binding constant is about 3.35×103 L/mol. When the concentration of PC is beyond CMC, most of Tb3+ is dimerized, the dimerization constant is about 3.92×104L/mol. In PC?CH?H2O system, the binding constant of Tb3+?CH complex 2.93×104L/mol is obtained.

基于TB-PC算法的MISO系统辨识的研究

如何保持MISO系统辨识的精确度、收敛度、耗时以及跳出局部最优解,是当今研究的热点和难点。提出了一种基于协同进化策略和禁忌搜索的蝙蝠和粒子群混合算法(TB-PC),分析蝙蝠算法控制参数,提出了合理的脉冲频度和音强初值,将蝙蝠算法与粒子群算法的优势用协同进化结合起来,并引入了禁忌搜索。通过对四个测试函数和MISO系统实例的辨识仿真,验证了TB-PC算法具有稳定性能好、收敛精度高等优点,对MISO系统有优良的辨识效果。
