Gaoya dianqi, 2019 针对干式空心电抗器匝间绝缘故障,采用磁矢位法对故障状态下空心电抗器电感量进行了分析。在分析过程中,考虑到故障线圈中环流所形成的磁场对干式空心电抗器电感量影响下,得出故障状态下干式空心电抗器电感量计算的精确解析表达式。在此基础上,利用电磁仿真软件MAGNET对干式空心电抗器磁场及故障线圈环流进行仿真分析,并对相同故障状态的电抗器进行不同频率下的电感量测量。由仿真和测试结果表明:故障线圈环流对干式空心电抗器电感量影响较大,其影响随着频率增大而增大,最终趋于稳定 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT As a core component in the electrochemical water splitting system, the cathode catalyst is capable of boosting the kinetics of the hydrogen evolution reaction (HER), while the scarcity and expenditure of current noble metal‐based electrocatalysts seriously restrict the large‐scale commercial development of hydrogen manufacturing devices. Here,

Dizhen xuebao, 2022 静态效应一直是影响大地电磁测深法精确性的主要原因之一。在相位校正法的基础上提出了一种更适用于电性变化较为平缓的地质情况的静态校正方法—最高频相位法，其核心是用需要校正测点两侧受静态效应影响较小测点的最高频视电阻率的算术平均值代替相位法递推公式中每个频点前一个频点的视电阻率值，以消除相位法中的误差积累。以二维模型的正反演为例，通过对比空间滤波法、相位法和最高频相位法对不同模型静态校正前后的正反演结果，证明了最高频相位法的有效性和优越性，同时表明，对于电阻率变化大并且静态位移严重的水平层状地层模型 ...

Jianzhu Gangjiegou Jinzhan, 2012 目前,空心钢管混凝土结构被大量应用和推广,但对其抗震性能的研究却比较少,制约了其在实际工程中的进一步应用。对空心普通和再生钢管混凝土柱的抗震性能进行了试验与有限元研究,首先介绍了3根空心圆钢管混凝土柱在定轴力和水平反复荷载作用下的滞回性能试验,分析了不同混凝土和空心率对试件耗能能力及位移延性等抗震性能的影响,研究表明再生混凝土构件的抗震性能要差于相应普通混凝土,而空心率越大,构件的延性和耗能能力越小。其次,采用有限元软件ABAQUS对空心钢管混凝土压弯构件的荷载-位移骨架曲线进行了大量数值计算 ...

Finding floral and faunal species richness optima among active fire regimes
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.
