A landscape‐scale framework to identify refugia from multiple stressors
Conservation Biology, Volume 36, Issue 1, February 2022., 2022 Abstract From a conservation perspective, quantifying potential refugial capacity has been predominantly focused on climate refugia, which is critical for maintaining the persistence of species and ecosystems. However, protection from other stressors, such as human‐induced changes in fire and hydrology, that cause habitat loss, degradation, and ...

Gaoya dianqi, 2021 为掌握SF6气体的低温放电特性,保证低温环境下SF6气体设备的运行可靠性。文中开展了-50℃至20℃温度范围内,半球头棒板电极下SF6气体的工频击穿试验。同时测量了降温过程中SF6气体的气压随温度的变化。获得了稍不均匀电场中绝对气压0.7 MPa和0.5 MPa的SF6气体的放电电压随温度的变化规律。发现当温度从20℃降低到-50℃时,SF6气体的放电电压和气压均呈现先缓慢降低,再迅速降低趋势,放电电压下降趋势的拐点与气压下降趋势的拐点基本一致,计算发现该拐点温度等于SF6气体的液化温度 ...

Dianci bileiqi, 2021 污秽绝缘子表面在低气压下容易出现飘弧现象,并在闪络过程中形成空气间隙电弧。绝缘子表面电弧和空气间隙电弧的U-I特性差异较大,而现有模型大多只是简单的用剩余污层表面电导率来计算表面电弧,无法准确低气压下的直流闪络特性。基于Obenaus模型,从理论上表面电弧和空气间隙电弧的差异,并利用这种差异性来作为判断直流污闪标准不同比例空气间隙电弧下的污秽度和气压指数的影响能力。结果表明:空气间隙比例不变时,污秽和气压的影响指数主要受电弧特性的影响且仅是常数,与绝缘子形状和电弧极性没有直接关系 ...

Gaoya dianqi, 2022 SF6/CF4混合气体主要应用于低温环境下的气体绝缘电气设备中，气固交界面是设备的绝缘薄弱环节，有必要研究低温环境下SF6/CF4混合气体中的绝缘子沿面闪络特性。文中首先分析了SF6/CF4混合气体的基本绝缘和液化特性，据此选择0.7 MPa 50%SF6/50%CF4混合气体进行-50～20℃温度范围内的圆柱形绝缘子沿面闪络试验，同时开展了0.5 MPa SF6气体在-35～20℃温度范围内的对照试验。其次采用威布尔分布分析了沿面闪络电压的概率分布特性。发现SF6 ...

Gaoya dianqi, 1994 [问]高原环境条件有哪些特点?它对高压电器的运行性能有什么影响?[答]高原环境条件的特点主要是:气压低、气温低、气温日变化大、绝对湿度低和太阳辐射强度比较强烈.由于低气压时的低空气密度会降低空气的耐电压强度、空气的冷却效应以及弧隙的空气介质恢复强度,所以高压电器的空气绝缘耐压下降,由空气冷却的零部件温度增高,并且在空气中灭弧比较困难.气温的日变化大,可能引起高压电器的密封不易保持以及机械结构变形或开裂.低气温对高压电器因气压或空气密度降低而引起的温度增高有补偿作用 ...

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions
Conservation Biology, EarlyView.Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The high operating temperatures and sluggish kinetics of Mg‐based hydrogen storage materials (HSMs) are urgently being addressed. In this work, a novel Mg–Ni–Ga HSM with dual‐phase synergistic catalysis is developed, including the fishbone‐like Mg3Ni2Ga1 catalytic phase and the Mg2Ni phase with stacking faults (SFs).
