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.

, 2019 : 冷链物流主要是指食品在生产到消费者食用前始终处于适宜的温度环境，以保障食品品质、降低流通过程中的损耗。冷链物流相比于传统物流而言是一项更复杂的系统性工程，受到政策和市场需求的影响呈现迅猛发展态势。但是，冷链物流企业长期以来因规模小、固定资产少、服务范围窄、服务规范性弱而发展困难重重，核心问题是资金的问题。政府引导和鼓励打造冷链物流产业园，推动产业园投资和建设主体打造平台，实现对园区内冷链企业的聚集效应并通过金融服务解决企业发展的资金问题。通过产融结合助力冷链物流企业发展 ...

Risk, Hazards &Crisis in Public Policy, Volume 15, Issue 2, Page 203-235, June 2024.Abstract Misinformation presents a challenge to democracies, particularly in times of crisis. One way in which misinformation is spread is through voice messages sent via messenger groups, which enable members to share information on a larger scale. Gaining user perspectives on digital misinformation interventions as countermeasure after detection is ...

Experimentally testing animal responses to prescribed fire size and severity
Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Deserts are often highly biodiverse and provide important habitats for many threatened species. Fire is a dominant disturbance in deserts, and prescribed burning is increasingly being used by conservation managers and Indigenous peoples to mitigate the damaging effects of climate change, invasive plants, and land‐use change. The size, severity,

Gaoya dianqi, 2017 为了提取泄漏电流安全区内体现绝缘子污秽度的特征信息,在反复试验的基础上,测取了4种污秽度下XP-70型绝缘子串的泄漏电流,采用了自适应阈值法对原始信号进行消噪,提取出安全区内的3个特征量:有效值均值、有效值最大值和有效值标准差,分析得出这3个特征量与绝缘子表面等值附盐密度呈指数拟合关系。选择了400组泄漏电流有效值特征量作为训练与识别样本,建立了基于概率神经网络的绝缘子污秽度预测模型。仿真和试验结果对比表明,模型预测准确率达87.5%。研究结果不仅对线路绝缘子清扫决策有一定的指导作用 ...

The Effect of Bispectrum Coupling Property on Fault Diagnosis [PDF]
, 2013 为了对双谱的耦合性质进行分析,同时利用三阶累积量和双谱对溢流阀进行故障诊断。由于双谱与三阶累积量相比,可以用来描述二次相位耦合,对比实验结果表明,故障的种类不同,其耦合信息对于这些故障判断的影响也不一样。实验中还通过二维小波在不同的方向上对故障信号和正常信号进行特征提取,然后将这些特征值输入支持向量机进行故障判别,实验结果表明,无论考虑耦合因素与否,这些故障信号在不同的频率部分与其正常状态的区分程度都不一样。In order to analyze the coupling properties of ...

Shuitu Baochi Xuebao, 2016 选取黄土丘陵区岔巴沟流域不同位置和不同沟道级别的30条典型切沟为研究对象，基于三维激光扫描技术（LIDAR），建立了基于高分辨率DEM提取切沟形态特征的方法，对比分析了0.1 m与5 m 2种分辨率DEM提取切沟形态特征参数的差异，实现对低分辨率DEM提取的切沟形态特征参数向高分辨率尺度转化。结果表明：基于三维激光扫描技术获取的0.1 m高分辨率DEM提取到的切沟形态特征值与手工测量的切沟形态特征值之间无显著差异，三维激光扫描技术提取切沟长度、宽度、深度、表面积和体积分别是手工测量的94.0%，109 ...
