亚稳相金属纳米晶因其优异的物理化学性质备受关注,然而如何可控合成亚稳相结构依然面临诸多挑战.本文报道了碱金属离子诱导亚稳相钌纳米晶(面心立方相)的可控合成策略.研究表明钌纳米晶结构和碱金属离子半径密切相关,因此通过改变碱金属离子实现了面心立方相和六方密堆相比例的连续调控.理论计算结果表明,碱金属的存在导致面心立方相的形成能低于六方密堆相,并且这种能量差随着碱金属离子半径的增大而增大.本工作为拓展亚稳态结构的实际应用奠定了基础.

Based on monthly runoff data of Hongjiadu,Guizhou from October 2013 to June 2015 and monthly runoff data of Yachi River,Guizhou from April 2014 to May 2015,using REOF and multiple linear regression analysis,regulation effect of water conservancy project in upper reaches of Wujiang River on monthly runoff of the river was analyzed. Seasonal temporal-spatial change of monthly runoff in Hongjiadu and Yachi River mainly contained two kinds of modalities. The first modality was that of Yachi River,which was main component of seasonal change of monthly runoff,and peak appeared in July. Space load of Yachi River modality was larger than Hongjiadu,and manual control ability of monthly runoff in Hongjiadu was larger than Yachi River. The second modality was that of Hongjiadu,and peak appeared in December. Space load of Hongjiadu modality was larger than Yachi River,and manual control ability of monthly runoff in Yachi River was larger than Hongjiadu. Seasonal changes of time components of two modalities had significant inverse phase. Regulation effect of Hongjiadu modality advanced Yachi River modality,and regulation effect of water conservancy project in Hongjiadu modality was larger than that of Yachi River modality,and seasonal distribution characteristics of regional rainfall was basically eliminated in Hongjiadu modality. Some seasonal distribution characteristics of regional rainfall were maintained in Yachi River modality. Monthly runoff modality of Yachi River had water storage regulation effect on a smaller part of regional monthly rainfall modality. Monthly runoff modality of Hongjiadu mainly had water storage regulation effect on south-north type of component of regional monthly rainfall,while most components of regional monthly rainfall modality did not have significant impact on monthly runoff modality of Hongjiadu.
