【摘要】

：

可再生能源的发展对新型储能器件提出了更高的要求,钠离子电池以其价格低廉、性能优异、环境友好等的特点,较锂离子电池在大规模储能领域具有更大的潜力。作为钠离子电池正极材料,Na3V2(PO4)3具有电压平台高、理论容量高等优点,并具有NASICON结构,但聚阴离子结构导致其导电性差,在充放电过程中难以进行快速的电子传递,通常采用纳米化以及碳包覆的手段来改善其导电性。

蛋白质超粗粒化优化算法的比较

蛋白质超粗粒化模型是近年来处于发展中的一种运用于超大生物分子体系模拟的理论模型。在超粗粒化模型中，一个超粗粒化粒子表示多个蛋白质的氨基酸残基。与一般基于蛋白质残基的粗粒化模型不同，超粗粒化模型能够用最少的粗粒化粒子表示蛋白质的二级结构，并可以进一步降低计算时间。
