±800 kV“U”型SF6气体绝缘穿墙套管绝缘性能分析

open access: yesDianci bileiqi, 2018
±800 k V特高压直流穿墙套管是我国±800 k V直流输电工程中的重要电力设备,但鲜有文献对其设计和绝缘结构优化进行报道。将金属屏蔽式"U"型结构用于穿墙套管设计,分析了±800 k V直流穿墙套管的实际运行环境和参数,同时将有限元分析方法应用于特高压直流穿墙套管的三维电场模拟。电场仿真结果表明:金属屏蔽条件下套管复合绝缘子表面电位和电场分布更加均匀,因此金属屏蔽式套管可实现其结构的紧凑型设计。另一方面,金属屏蔽式结构套管高场强区域主要集中在内部金属屏蔽和外部均压环区域 ...

Evolutionary and environmental determinants of heat tolerance and acclimation capacity in herpetofauna

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Exploring heat tolerance and acclimation capacity can provide an effective approach to evaluating species’ sensitivity to extremely high temperatures due to climate warming. Despite some work on amphibian and reptile thermophysiological adaptation, related questions remain. We reviewed the literature to provide a synthesis of worldwide data on

基于磁记忆的导管架平台关键构件预检测研究

open access: yesShiyou jixie, 2015
随着服役年限的增加,导管架海洋平台结构将产生缺陷和损伤。金属磁记忆技术可实现对铁磁性金属构件内部应力集中区的检测,因此可用于对导管架平台结构的应力集中检测。在介绍金属磁记忆检测机理后,将该技术应用到导管架平台结构预检测上,并以CEP导管架平台上部组块为对象开展了应力集中检测。经与超声检测结果对比,验证了金属磁记忆技术在导管架平台结构检测的适用性。研究结果表明,金属磁记忆检测能快速准确地对平台结构进行应力集中检测,其检测结果可为平台年检计划的制定提供依据和参考。

Traditional knowledge promotes the protection of large old trees: A case from China's richest biocultural diversity area

open access: yesPeople and Nature, Volume 7, Issue 11, Page 2700-2713, November 2025.
Abstract Large old trees are important ecological entities in human settlements, providing cultural values and ecological services that are threatened by current and future changes in global climate, land use and disturbance regimes. Some studies suggest incorporating social and cultural significance into the conservation of large old trees.
