A kind of sandwich-like NiCo_2O_4/rGO/NiO heterostructure composite has been successfully anchored on nickel foam substrate via a three-step hydrothermal method with successive annealing treatment. The smart combination of NiCo_2O_4, reduced graphene oxide(rGO), and NiO nanostructure in the sandwich-like nano architecture shows a promising synergistic effect for supercapacitors with greatly enhanced electrochemical performance. For serving as supercapacitor electrode, the NiCo_2O_4/rGO/NiO heterostructure materials exhibit remarkable specific capacitance of 2644 mF cm^(-2)at current density of 1 mA cm^(-2),and excellent capacitance retentions of 97.5% after 3000 cycles. It is expected that the present heterostructure will be a promising electrode material for high-performance supercapacitors.

萍水河湘东段区域受洪水灾害影响较大,历年损失严重。本文使用MIKE FLOOD构建了萍水河湘东段区域洪水演进一二维耦合模型,结合2019年实测水位过程和调查洪痕等资料验证了模型合理性。根据研究区设防情况,确定了20年、50年和100年一遇3种设计洪水计算方案,并分别提取了3种计算方案下的洪水风险特征要素(包括最大淹没水深、最大演进流速和淹没历时等),使用综合风险度法开展了萍水河湘东段区域洪水风险区划研究。结果表明:萍水河湘东段区域洪水风险区划分为极高、高、中和低风险4个等级;其中,中下游无堤防保护区域洪水风险等级为极高或高风险;湘东区县城区域洪水风险等级主要为高风险和中风险,县政府驻地区域属于洪水灾害高风险等级区。本文洪水风险区划成果可为湘东区防洪规划及非工程措施建设提供科学依据。
