Jianzhu Gangjiegou Jinzhan, 2014 群智能优化算法已被证实可以用于解决实际工程的优化问题。水循环算法可对约束问题进行求解。基于自然界中水循环过程提出的一种新型智能优化算法———水循环算法(WCA),研究了其应用于空间桁架结构优化设计问题的可行性及有效性,论文对两个空间桁架结构进行了截面优化计算分析,并与已有文献优化结果进行了比较,研究结果表明:WCA优化算法相对于群搜索算法(GSO)、启发式粒子群优化算法(HPSO)等优化算法能够提供更快的收敛速度,收敛结果也更好。

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT VO2 is a promising thermochromic material, but it is still limited by low transparency, weak solar modulation, and poor stability. Here, we develop a coordination‐compound‐derived strategy to construct a hierarchical BiVO4/VO2@BiVO4 film with a core–shell@nanosheet structure.

, 1996 利用激光气化铁氰化钾或亚铁氰化钾并利用飞行时间质谱检测方法对氰化钾团簇的形成机理进行了研究，结果发现：团簇正离子可归属为（Ｋ（ＫＣＮ）ｎ＾＋，ｎ＝０～３７，它们的幻数为ｎ＝４，１３，２２，３７；团族负离子可归属为（ＫＣＮ）ｎＣＮ）＾－，ｎ＝０～１３，它们的幻数为ｎ＝４，１３。这些幻数与氯化钠等碱金属卤化物团簇体系完全一致。这表明：它们的团簇结构应该是相同的，即１×３×３（ｎ＝４）３×３×３（ｎ＝
