Gaoya dianqi, 2022 近年来,利用海上漂浮式风电平台开发风电资源逐渐成为能源开发的重要发展方向之一。动态海缆作为风机与静态海底电缆间的连接装置,是海上能源输送系统的关键设备。在动态海缆运行过程中,其往往面临着电—热—机械等多种失效因素,这对动态海缆的关键材料尤其是绝缘材料的性能提出了更高的要求。文中针对一种超纯净均聚抗水树交联聚乙烯材料进行研究,结合动态海缆可能面临的失效风险因素,对绝缘材料的机械性能、电气性能及耐温性能进行测试,验证材料作为动态海缆绝缘材料的适用性。

Asian Politics &Policy, Volume 18, Issue 3, July 2026.ABSTRACT Gray‐zone activities have become a central feature of security competition in East Asia, particularly in the Taiwan Strait, where persistent military operations blur the boundary between coercion and armed conflict. This study develops a structured threat‐assessment framework for evaluating the intensity of PLA aerial gray‐zone pressure around

, 2018 1987年,两岸长达38年的隔绝状态被打破后,人员往来和各项交流迅速开启。两岸由过去长期的对峙逐步迈向交流、对话与合作。三十年以来,两岸关系走过了一个高潮迭起的历程。尽管其间台海危机及两岸风险事件不断,但台海区域及两岸关系总体上维持了一个稳定的局面,有效地阻止了\"台独\"分裂势力企图把台湾从中国分离出去的野心。大陆对台海危机的管理基本上达到了预期的目标。随着中国大陆综合国力的快速提升,大陆在应对台海危机及其风险方面的管理能力不断提升,空间不断扩大。2016年度教育部人文社会科学重点研究基地重大项目 ...

, 2023 随着海上风机的大型化和风电场所在海域水深的增加，海上风机基础需要承受更大的水平荷载和弯矩荷载。加翼单桩能有效提升风机基础承载能力，但侧翼结构对桩基周围局部冲刷的影响目前尚不明确。在波流水槽中开展了大直径加翼单桩动床冲刷模型试验，研究纯流和波流共同作用下加翼单桩的冲刷特性。试验结果表明：加翼单桩周围局部冲刷特性受到来流强度、方向和类型的显著影响；当水流强度较小时，加翼单桩相较于传统的单桩基础具有较好的冲刷防护效果，防护效率最高可达20.7%；当水流强度较大或波流叠加情况时，加翼单桩的防护效应可能消失 ...

Integrative Conservation, Volume 5, Issue 1, Page 125-136, March 2026.We collated detections of the sun bear from new and previously published camera trap studies across its range. We then analysed these detections at two different spatial scales to assess the habitat associations and diel activity of this species. We found that the sun bear is tolerant to moderate habitat disturbances. ABSTRACT Degraded tropical forests,

Achieving Transboundary Water Security Through Water Innovations: A Framework and Cases
World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Alternative sources of freshwater, provided by various innovations, have long been available to countries facing acute water stress. We hypothesize that avoiding and/or resolving conflict with neighbors—caused by the uncertainty of continued access to shared surface water and groundwater sources—is another driver of innovation adoption ...

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...

Kongjian kexue xuebao, 2023 卫星散射计通过测量海表粗糙度反演全球海面风场。对于Ku波段散射计，海表粗糙不仅和海面风场相关，还受海表温度的二阶效应调制。定量研究了海表温度对中法海洋卫星（CFOSAT）散射计（CSCAT）反演风速和后向散射测量的影响。结果表明，CSCAT两种极化方式测量的后向散射系数都会受到海表温度的影响，但是垂直极化中低入射角（θ < 36°）测量的后向散射系数几乎不随温度变化。因此CSCAT的风速偏差也随海表温度的变化而变化，且随着入射角的增大和风速的减小，海表温度对风速偏差的影响程度增大 ...
