Magnesium-based energy materials, which combine promising energy-related functional properties with low cost, environmental compatibility and high availability, have been regarded as fascinating candidates for sustainable energy conversion and storage. In this review,we provide a timely summary on the recent progress in three types of important Mg-based energy materials, based on the fundamental strategies of composition and structure engineering. With regard to Mg-based materials for batteries, we systematically review and analyze different material systems, structure regulation strategies as well as the relevant performance in Mg-ion batteries(MIBs) and Mg-air batteries(MABs), covering cathodes, electrolytes, anodes for MIBs, and anodes for MABs;as to Mg-based hydrogen storage materials, we discuss how catalyst adding, composite, alloying and nanostructuring improve the kinetic and thermodynamic properties of de/hydrogenation reactions, and in particular, the impacts of composition and structure modification on hydrogen absorption/dissociation processes and free energy modification mechanism are focused;regarding Mg-based thermoelectric materials, the relations between composition/structure and electrical/thermal transport properties of Mg_(3)X_(2)(X = Sb, Bi), Mg_(2)X(X = Si, Ge, Sn) and Mg Ag Sb-based materials, together with the representative research progress of each material system, are summarized and discussed. Finally, by pointing out remaining challenges and providing possible solutions, this review aims to shed light on the directions and perspectives for practical applications of magnesium-based energy materials in the future.

预算绩效目标体系是全面实施绩效管理的关键。针对当前设置不完善与标准不明确并存的问题,可将其界定为个体目标结构和场域目标联结两个层次,融合形式、价值与功能标准来梳理其不同状态。聚焦于目标的初始形成,利用规定任务、自选动作及贯穿两者的绩效竞争来搭建框架,可进一步解释目标体系完善或异化的可能原理。规定任务和自选动作分别对应目标的纵向约束关系与横向扩张机制,两者各有丰富内容、规范限度并蕴藏鲜明的绩效竞争策略;叠加于个体决策者身上,其力量均衡有助于目标体系完善,力量失衡则引发目标异化。本文采用嵌入式系统型案例法收集了N省工信系统共122份经验材料,分析结果可为预算绩效目标优化设置与纠偏提供有限参考。

作为政府绩效评价前沿的公共政策绩效评价面临独立深化发展的紧迫诉求。明确其为一种独特评价类型,是源自公共政策主体结构、共识型决策机理以及评价技术范式成长对于专属性空间的需要。它跟公共政策评价区别主要在于技术方法,跟财政支出绩效评价区别在于内容重点,跟部门履职和政府整体绩效评价区别在于问责效力。公共政策绩效评价具有体系结构与制度功能上的鲜明优势,以绩效为导向的政策预算管理将驱使政府组织行为走向灵活。未来应从价值导向、组织机制、技术标准与知识运用等方面着力,进一步推动该类评价实践良性扩张。

预算全面实施绩效管理是对我国已开展10多年财政支出绩效评价实践的扬弃,是优化财政资源配置与推进国家治理现代化的内在要求。从过程来讲,预算全面绩效管理需要顶层设计技术体系的架构、功能及运行,优化既有技术模块和建立面向新预算形态及管理环节的技术标准,即将技术模块切割改造并重组为完整、灵活的集成技术系统。从要素与逻辑来讲,需致力于分步构建和不断发展预算全面绩效管理知识库。完整的预算全面绩效管理知识体系建构是一个庞大而复杂的工程,考虑现有技术条件和体制环境,预算全面绩效管理各类知识的集成需要分步实施。就预算全面绩效管理集成技术与知识体系的互动应用而言,一方面,集成知识库可随时为新增的绩效管理需求提供技术支援;另一方面,集成技术体系可作为检索、评估和碎化潜在入库知识的科学标尺。
