Dizhen xuebao, 2023 针对2011年提出的两步差法在地震微波异常提取中的不足，提出了改进两步差法，该方法通过使用层次聚类和小波分析两种算法，克服了原方法中未考虑不同地物类型引起的亮温差异、亮温背景场不够稳健等问题，从而使异常结果在空间形态和异常幅度上更加合理，并将该方法应用于2021年5月22日青海省玛多县MS7.4地震的微波异常提取。结果显示，玛多地震前三个月出现了一条长约900 km、增温幅值达12 K的NE向亮温增温条带，与2010年4月14日MS7.1玉树地震前异常特征在空间分布和演化特征上均有很高的相似性。此外 ...

Genetic origins and climate‐induced erosion in economically important Asian walnuts
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

Dizhen xuebao, 2019 选取2011—2016年发生的38次震中距大于1 000 km的MW≥7.5地震震后3小时的连续波形资料，利用人工检视方法对这38次地震是否触发了我国台湾地区的非火山型微震颤进行了调查。分析结果显示：这38次地震中有4次远震触发了非火山型微震颤，事件持续300—500 s不等。利用网格搜寻方法对此4次微震颤事件进行了定位，确定震中位于台湾中央山脉南段，震源深度为21—53 km。结合研究区内地球物理观测资料，分析认为是由于远震产生的面波改变了研究区内的瞬时应力，进而导致断层蠕滑触发了微震颤事件。

Yttrium Addition Co‐Enhances the Plasticity and Corrosion Resistance of TiB2‐Refined Al‐Mg‐Zn Alloys
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT To address the degradation of corrosion resistance induced by Al‐5Ti‐B grain refiner during the strengthening of Al‐Mg‐Zn alloys, this study innovatively employed a rare earth element yttrium (Y) alloying strategy to achieve synergistic enhancement of mechanical strength and corrosion resistance.

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT The central challenge in the development of high‐performance electromagnetic wave‐absorbing materials lies in achieving an optimal balance between impedance matching and attenuation characteristics. This is particularly critical for purely dielectric absorbers, where precise tailoring of the real (ε′) and imaginary (ε″) parts of the complex ...

Shuitu Baochi Xuebao, 2020 采用原状土冲刷水槽法和静水崩解法测定土壤抗冲性和抗蚀性，以云冷杉红松林（PA）和椴树红松林（TP）的林隙和郁闭林分为对照，分析了小兴安岭地区2种林型由掘根倒木形成的不同丘和坑微立地类型及其土壤性质对土壤抗冲性和抗蚀性的影响，旨在揭示它们与土壤抗侵蚀能力的关系。结果表明：在2种林型下由掘根倒木形成的丘和坑微立地上，土壤砂粒含量均较高，其抗侵蚀能力均较弱，而对照却相反；2种林型下丘和坑微立地的土壤容重均与土壤抗冲性和抗蚀性呈无显著的负相关（P>0.05），而PA对照的土壤容重与它们均呈不显著正相关（P>0 ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Vanadium oxides are deemed competitive cathode candidates for aqueous zinc‐ion batteries (AZIBs), benefited from their high theoretical capacity and multiple crystalline structures. However, the sluggish reaction kinetics, poor reversibility, and high solubility have hindered the practical application.

Highly Stable CsPbBr3@Cs4PbBr6 Perovskite Fluorescent Nanomaterials for White Light‐Emitting Diodes
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Although halide perovskite nanocrystals exhibit excellent photoelectric properties, their inherent instability greatly limits their practical applications. Here, we report a novel self‐assembly strategy to synthesize highly stable CsPbBr3@Cs4PbBr6 perovskite fluorescent nanomaterials in a single step by using 4,4′‐azo (4‐cyanoglutaric acid, CA)

Review of Policy Research, Volume 43, Issue 1, January 2026.Abstract Populist radical right parties are on the rise all over Europe. Recent literature investigates their effects on environmental policy, however, often applying an overly broad perspective on the policy area and neglecting causal mechanisms. This article addresses both gaps in an in‐depth case study of partisan effects on Swedish environmental ...
