Dianci bileiqi, 2020 城市配电线路建设会存在架空线路与埋地电缆混合传输现象,需要合理分析混合传输系统雷击可靠性以进行针对性防护。通过EMTP软件建立架空线路与埋地电缆混合传输系统模型,利用事件树方法估算系统雷击可靠性,分析电缆避雷器安装方式、杆塔接地电阻、埋地电缆长度等因素对系统雷击可靠性影响,最后讨论缩短故障修复时间提高系统雷击可靠性效果。研究结果表明:埋地电缆两端均安装避雷器时,系统雷击可靠性最高,略高于仅在一端安装避雷器情况。系统雷击可靠性随着线路杆塔接地电阻或埋地电缆长度的增加而降低 ...

Structural Modulation of Magnetic Softness in Fe‐Based Amorphous Alloys via Pulse Current Training
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Fe‐based amorphous alloys, despite their intrinsically low magnetocrystalline anisotropy, suffer from quasi‐dislocation dipoles and localized stress fields that impede domain‐wall motion and increase coercivity. Here, we introduce pulse current training (PCT) as an energy‐efficient technique to overcome these limitations in a Fe76Si9B10P5 ...

, 1999 可靠性是财务会计的核心概念。可靠性与相关性“统御”的会计信息质量特征是联结信息使用者需求（体现在会计目标上）和信息生产过程（确认、计量、报告）的“钮结”。具体而言，相关性指向的是信息使用者的外在需求，而可靠性映射出的是财务会计这一信息生产系统的本质属性。人们对会计信息“量的需求”和财务会计自身“质的规定”之间的矛盾往往集中反映在对相关性和可靠性“孰重孰轻”的价值判断，以及随之形成的可靠性——相关性均衡之上。随着信息使用者群体中投资者比重的日益增大，人们越来越重视不确定性程度较高的前瞻性经济信息 ...

Policy, Waste, and Power: Textile Dumping in Chile's Atacama Desert
Latin American Policy, Volume 17, Issue 2, June 2026.ABSTRACT Globally, 87% of textile fibers end up incinerated or in landfills, with Chile bearing the brunt of this crisis. Every year, 39,000 tons of discarded clothing are illegally dumped in the Atacama Desert, turning it into a sacrifice zone for the Global North's waste economy.

Veterinary Dermatology, Volume 37, Issue 3, Page 353-364, June 2026.ABSTRACT Background Canine atopic dermatitis (cAD) is a multifactorial, inherited skin disease, estimated to affect ≤ 15% of dogs. Studies of skin messenger mRNA in cAD currently use invasive methods, including blood sampling and biopsy collection, whilst advances in human atopic dermatitis study methodology have demonstrated reliable use of minimally ...
