柞蚕丝素蛋白与细胞具有特异性相互作用,作为生物医用材料具有潜在的研究和开发前景.凝胶是组织再生支架的重要材料形态之一,而迄今国内外尚无对柞蚕丝素蛋白凝胶化行为的系统性研究报道.本文研究了环境温度、pH值、柞蚕丝素溶液的浓度以及K+、Ca2+的浓度对再生柞蚕丝素蛋白的凝胶化速率的影响,研究了溶胶-凝胶转变过程中柞蚕丝素蛋白构象的变化.结果表明,再生柞蚕丝素蛋白的凝胶化时间随着溶液中丝素蛋白浓度的增大和环境温度的升高而显著缩短.发现柞蚕丝素蛋白的溶胶-凝胶转变速率比同条件下的家蚕丝素蛋白快得多,且对溶剂

采用PSM方法对102Zr原子核的能带进行了理论计算,很好地再现了实验结果.另外,通过对晕带,准粒子转动带,边带的能量,带头对应组态的分析,得出了形成这些轴对称形变带的微观机制:低激发形变带主要是位于N=4和N=5壳层上的高j侵入态1g7/2和1h11/2引起的;特别是v5/2-[532],v3/2+[411]和v3/2+[413]轨道上的准粒子对该原子核形变的发生起了主要作用.
基于轴对称形变约束的相对论平均场理论,考虑微观质心修正,计算了Zr同位素链偶偶核的位能曲面,并利用Strutinsky壳修正方法从相应的单粒子能级中提取了壳修正能量,研究了Zr同位素链的壳结构变化.结果表明,形变约束的相对论平均场理论能很好地描述Zr同位素链的基态性质.Zr同位素链壳修正能量显示出明显的壳效应,随中子数变化有较强的同位旋依赖性;同时,Zr同位素链壳修正能量具有复杂的形变依赖性,对稳
