Conservation Biology, Volume 39, Issue 4, August 2025.Abstract Marine protected and conserved areas (MPCAs) are promoted as an ecosystem‐based adaptation (EbA) approach to increase community and ecosystem resilience to climate change. However, traditional approaches to MPCA design typically do not consider climate risk or habitat condition under a climate threat.

Research of New MFL Testing Technology Based on the Condition of Variable Excitation [PDF]
, 2016 储罐和管道是石化工业中石油和天然气的主要载体，储罐和管道的腐蚀不可避免的造成石油和燃气的泄漏，并进而引发爆炸等事故。因此，对储罐和管道的安全检测，对于保障人民生命、财产以及防止环境污染等具有重要的意义。漏磁检测技术属于无损检测范畴，是储罐和管道检测中最常用的检测手段之一。内、外表面缺陷的区分问题一直是漏磁检测技术的一个技术难题，本文提出了变励磁条件下的新型漏磁检测技术，可有效检测缺陷并实现内外表面缺陷的区分。 本文首先分析了漏磁检测技术以及无损检测技术的研究背景和现状 ...

Long‐Distance Corridors Facilitate Asian Elephant Adaptation to Climate Change 长距离廊道有助于亚洲象适应气候变化
Integrative Conservation, Volume 4, Issue 1, Page 57-70, March 2025.Climate change presents significant challenges for Asian elephants, forcing them to either remain in degraded habitats or seek new ones. But, remaining would lead to resource shortages, while moving is hindered by movement barriers. This study integrates species distribution models (MaxEnt) and the minimum cumulative resistance (MCR) model to construct

International Social Security Review, Volume 78, Issue 1, Page 29-56, January/March 2025.Abstract Street‐level professionals, such as social workers, shape policy implementation by exerting discretion. However, it remains unclear how other street‐level bureaucrats (SLBs), who are not considered to hold a professional status and who perform highly regulated activities, can do the same. Even though the decision‐making leeway of these SLBs is

Gaoya dianqi, 2021 架空地线因其不存在负载电流(除了很小的感应电流外),在冬季冰冻雨雪天气下较输电导线更易产生覆冰现象。而为了达到防雷效果,架空地线必须经铁塔可靠接地,这与在通电融冰工况下需使其对地绝缘相矛盾。文中针对所提出的一种220 kV防雷防冰灾架空地线系统,在简介其拓扑结构与工作原理基础上,根据该架空地线电缆参数及假设的融冰场景,通过计算直流融冰电流、电压,确定直流融冰电源的额定输出容量,并对该直流融冰电源的全桥模块化多电平换流器等核心部件的结构参数、元器件选型等进行了分析计算 ...

Conservation Biology, Volume 38, Issue 3, June 2024.Abstract Ecosystem state transitions can be ecologically devastating or be a restoration success. State transitions are common within aquatic systems worldwide, especially considering human‐mediated changes to land use and water use. We created a transferable conceptual framework to enable multiscale assessments of state resilience and early warnings ...

Gaoya dianqi, 2013 同塔双回输电线路架空地线逐基接地时,架空地线的感应电流和电能损耗是值得关注的问题,目前关于架空地线损耗的定量研究较少。通过对广东某220 kV同塔双回输电线路架空地线感应电流进行了现场实测,使用ATP-EMTP程序对该线路感应电流进行仿真计算,实测值与计算值吻合较好。计算讨论了同塔双回架空线路导线相序排列方式、线路电流大小和线路电流不平衡度对架空地线感应电流和电能损耗的影响。结果表明,架空地线感应电流和线路电流变化呈线性关系,地线电能损耗与线路电流增大呈平方关系 ...
