China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition
Antipode, Volume 57, Issue 3, Page 830-861, May 2025.Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.

Gaoya dianqi, 2016 为了适应变电设备向大容量化、高电压化、结构多样化、密封化及设备状态检修的发展趋势,笔者在区间物元可拓原理、云模型和灰色模型的组差值法的基础上,建立基于多源信息的变压器两级和综合评价模型,给出了变压器单因素指标的趋势预测评价和整体状态评价的具体方案。在两级评价中利用顶层油温、绕组热点温度和负载能力计算综合相对劣化度并得到自然模式和加速劣化模式的综合评价分值,在综合评价中利用统计模型得到不良工况和可靠性对运行状态进行补充,首次建立负载能力模型和故障预测模型,对变压器运行状态进行修正 ...

The need for carbon finance schemes to tackle overexploitation of tropical forest wildlife
Conservation Biology, Volume 39, Issue 1, February 2025.Abstract Defaunation of tropical forests, particularly from unsustainable hunting, has diminished populations of key seed dispersers for many tree species, driving shifts in forest community composition toward small‐fruited or wind‐dispersed trees with low wood density. Such shifts can reduce aboveground biomass, prompting calls for overexploitation to

Gaoya dianqi, 2014 在传统的变压器状态评价方法中,常权无法客观反映变压器部分参数偏离正常值时对整体评价影响。基于此,笔者提出了基于变权重的变压器模糊综合状态评价方法。首先采用层次分析法确定变压器各影响因素指标的权重,然后考虑实际情况对各影响因素权重进行变权处理,减少评价的主观性,使变压器的状态评价结果更为合理。应用文中方法对实际变压器进行状态评价,验证了该方法的合理性和可行性。

滨海城市“气候承载—空间适应”方法研究——厦门气候承载空间模拟分析 [PDF]
, 2018 城市气候承载力作为城市适应气候变化的核心测度,反映城市系统与气候系统之间互馈关系,其空间状态关乎城市安全与可持续发展。基于DPSIR和状态空间法,构建城市气候承载空间概念模型、气候承载力评价指标体系与评测模型,提出气候承载—空间适应方法体系;结合GIS,以厦门为具体案例城市,定性、定量、定位进行城市气候承载空间模拟分析,创建城市气候承载地图(UCC Map),判定气候承载—空间适应热点区域,进而提出城市气候承载—空间适应优化建议。以补充\"气候变化\"与\"城市空间\"相互调节适应的空白 ...

World Medical &Health Policy, Volume 16, Issue 4, Page 774-782, December 2024.Abstract There has been longstanding international fascination with the British National Health Service since it was established in 1948. The British population itself has offered enduring support for the principles and institutions of public provision. However, coverage of the NHS has typically been uneven in academic and policy debates.

Dianci bileiqi, 2015 变电站防雷与接地装置是电力系统中的重要设备,是电力系统发生接地短路时设备与人员安全的重要制约因素,其评价结果也是指导制定年度技改大修计划的关键依据。目前,对变电站防雷与接地装置的状态评价主要依据Q/GDW611-2011《变电站防雷及接地装置状态评价导则》执行。随着状态评价工作的持续开展,笔者对评价导则中的若干评分项目存在困惑,在对其分析阐述的同时提出了一些建议,目的是希望能够促进评价导则更加客观、高效地评价设备的真实状态。文章同时对防雷与接地装置的评价工作提出了若干建议。

A universal Carlson's index formula based on genetic algorithm optimum [PDF]
, 2001 在适当设定湖泊富营养化指标“基准值”的情况下,用相对于“基准值”的指标相对值替换Carlson指数公式中的指标值,公式中的系数可视为与指标特性无关.采用遗传算法对公式中的待定系数进行优化,得到对多项指标都通用的富营养化的普适Carlson指数公式.并用折衷型激励功效函数法对单项指标Carlson指数赋权,计算综合指数.公式已被用于我国50多个湖泊、水库的营养状态评价,证实了其正确性.该公式计算简单,使用方便,具有客观性、可比性和通用性.：Based on the hypothesis of “base ...

Ultrasound in Obstetrics &Gynecology, Volume 63, Issue 2, Page 164-172, February 2024.ABSTRACT Objective Most of the published literature on selective fetal growth restriction (sFGR) has focused on monochorionic twin pregnancies. The aim of this systematic review was to report on the outcome of dichorionic diamniotic (DCDA) twin pregnancies complicated by sFGR.
