大气重力波是临近空间中重要的动力学过程之一，并且广泛存在于全球大气层中，研究其全球分布及变化规律，对理解大气动力学具有重要意义。全球卫星导航系统（GNSS）可以通过掩星的方式来获取临近空间大气的温度信息，并且具有全球覆盖、垂直和水平分辨率较高的优点，从而被广泛应用于临近空间大气重力波研究。利用气象卫星风云3号C星（FY-3C）搭载的全球导航卫星掩星接收机（GNOS）的探测数据来反演全球重力波扰动分布，反演得到了2015－2019年这5年间的全球重力波分布，并着重分析了全球重力波的季节变化、年际变化以及长波和短波重力波的全球分布和特征。结果表明，冬夏两季的重力波扰动要强于春秋两季，并且呈现冬季半球强于夏季半球的现象; 同时还发现，重力波扰动的强度随着高度增加而逐渐增强；在20～50 km的高度范围内短波重力波强度大于长波重力波强度。

旨在为选育性状优良、适合于油用开发的滇牡丹种质资源提供参考，对人工栽培在同一环境的9个种源滇牡丹籽百粒鲜质量和百粒干质量、含水率、可溶性糖含量、可溶性蛋白含量、粗脂肪含量、脂肪酸组成及含量进行了测定，对各指标之间的相关性及各指标与种源地地理因子的相关性进行分析，对脂肪酸组成进行主成分分析（PCA）和聚类分析。结果表明：人工栽培到同一环境后，不同地理种源滇牡丹籽各指标均存在一定差异，其中可溶性蛋白（变异系数21.76%）、亚油酸（变异系数19.57%）及豆蔻酸（变异系数18.52%）差异较大；丽江河西种源滇牡丹籽粗脂肪含量最高，达到21.64%；丽江鲁甸种源滇牡丹籽中的α-亚麻酸含量最高（42.84%）；相关性分析表明，百粒鲜质量（p

(中医护理措施具有疏通经络和排乳止痛的功效, 能够改善急性乳腺炎患者的临床症状, 促进疾病转归。本研究就中医护理技术在急性乳腺炎早期患者中的应用现状进行综述, 以期拓展对急性乳腺炎患者的护理新思路, 进一步推动中医护理技术在急性乳腺炎早期患者中的应用。)

能源互联网的建设不仅需要技术手段的支撑，更需要以价值为驱动激活各方主体参与，打造互惠共赢的能源生态圈。为此，从能源、信息和制度经济学的视角出发，深入分析能源互联网的价值创造机理、业态创新范式和发展战略选择。首先，剖析了能源互联网的价值创造机理，其本质是以多能融合突破孤立系统的边界，从而显著扩大资源优化配置的空间；通过信息技术使得能源系统更加有序，进而促进能源系统的“熵减”；通过能源互联网平台释放范围经济的巨大红利。其次，设计了基于共享经济机制、降低交易成本、激励共享共赢的能源互联网价值分配机制，谋划了能源互联网支撑智慧城市发展、支撑绿电追踪、支撑能源消费节能降耗、提升工业资产利用率、助力政府治理的新业态。最后，策划了以再电气化为核心目标、基于价值公平分配的数据共享、以数字孪生为平台的人工智能、以负荷调度替代需求侧响应、基于共享经济的能源互联网市场机制的发展战略。

南非是非洲最具影响力的国家之一，也是全球主要温室气体排放国之一。随着全球气候变暖形势越发严峻以及本国优质煤炭资源日趋紧张，南非近年来开始积极推进能源低碳转型并提出2050年实现碳中和的减排目标。首先详细介绍了南非能源结构和碳排放现状，其次概述了南非碳中和目标的实现路径以及涉及电力、工业、交通运输、建筑、农林等领域的减排政策、规划和措施，并指出了所面临的主要困难和挑战。南非的相关实践对其他发展中国家具有重要的参考意义。
