Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Metal oxide semiconductor‐supported noble metal nanoparticles are common sensing materials for gas sensors. However, the large size and their tendency to migrate at high temperatures often lead to inferior sensing sensitivity and stability. Herein, a salt‐assistant strategy is developed to prepare fully‐exposed Ir clusters on SnO2 nanorods ...

Robust metrics for quantifying and comparing resistance and recovery in experimental studies
Methods in Ecology and Evolution, Volume 17, Issue 1, Page 6-14, January 2026.Abstract Various indices have been developed to experimentally quantify resistance and recovery (two components of engineering resilience) in response to anthropogenic and natural disturbances. This diversity complicates the selection of appropriate metrics for comparing resilience across ecosystems and studies.

Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Identifying refugia from emerging threats is vital to ensure the persistence of rare and threatened species, but modeling habitat distribution for these species is challenging and the role of people in refuge management is rarely considered. Myrtle rust is an emerging infectious disease that represents a grave threat to the rare wetland tree ...

Shuitu Baochi Xuebao, 2020 掌握四川省省级水土流失重点防治区水土流失情况、空间分异规律及其内在驱动因素对生态预警和土壤侵蚀治理等具有重要意义。应用中国土壤流失方程（CSLE）计算四川省省级水土流失重点防治区土壤侵蚀状况，通过不同土壤侵蚀敏感性评价方法识别中国土壤流失方程（CSLE）敏感因子，借助地理探测器探究重点防治区土壤侵蚀空间分异规律及其内在驱动力。结果表明：四川省省级水土流失重点防治区水土流失面积占比27.16%，平均土壤侵蚀模数为806.08 t/（km2·a），属于轻度侵蚀，但区内土壤侵蚀差异明显，局部存在严重水土流失 ...

Conservation Biology, Volume 39, Issue 6, December 2025.Abstract As the coverage of area‐based conservation increases across the globe, it is critical to improve understanding of the social and ecological outcomes of such measures and the pathways to their outcomes. A social–ecological systems approach to monitoring and evaluation is increasingly advocated; yet, applications remain scarce.

Gaoya dianqi, 2016 目前CVT误差校验的主要方法为离线校验法,存在着校验工作量庞大以及校验结果偏离CVT在线状态下的实际值等问题。笔者提出了一种利用在运容性设备协助CVT进行在线校验误差的新方法。在变电站中大量使用的LVQB型电流互感器结构基础上,设计改造使其具备高压标准电容器功能,通过在其末屏接地线处串入低压标准电容器和电子分压器组成标准电容分压器,即可实现对CVT误差的在线校验。这种新型在线校验方法规避了在变电站在线直接投切标准电容分压器的风险,同时在完成对站内CVT的校验工作之后,恢复LVQB型电流互感器的正常接地 ...

Journal of Linguistic Anthropology, Volume 35, Issue 2, August 2025.Abstract This article argues that social actors' media ideologies about digital interfaces are key to the enregisterment of online activities. Focusing on an online register emergent from user activities around Year, Hare, Affair (YHA)—a state‐aligned Chinese animation—I explore how different metadiscourses evaluate this register by entextualizing ...

Gaoya dianqi, 2019 为研究分析一起电化学传感器法进行六氟化硫（SF6）气体分解产物带电检测发现的GIS电压互感器设备异常,使用不同的分解产物带电检测方法并结合电气试验和解体检查进行了综合分析。结果表明,该带电检测结果是一种未见报道的SF6气体中H2体积分数异常现象。不同厂家生产的电化学传感器仪器带电检测结果不准确且差异较大,色谱仪更能准确地检测分析故障气体。该电压互感器缺陷的主要原因是生产时使用了退役变压器硅钢片,带入了变压器油等污染物;同时,制造工艺不完善使铁心磁通异常,铁心过励磁下低能放热导致溶解气体逐步析出 ...

臺灣教育社會學研究, 2014 本研究從成人學習取徑出發，以Jarvis的經驗學習觀點為理論架構，探索及了解東南亞籍新移民女性因應環境風險的經驗學習歷程及其構成要素。 在研究方法上，本研究採取質性詮釋典範，深度訪談六位居住於北部兩個都會區的東南亞籍新移民女性。研究結果發現，東南亞籍新移民女性的學習型態隨著環境議題性質及關懷對象的不同而呈現三條路徑：非學習、非反思性行動學習、反思性混合學習型態。反思性經驗學習歷程隨著居臺時間長短及感受的變化而漸次進入三個階段：「被動順應」、「主動融入」及「創新再造 ...
