Dianci bileiqi, 2022 我国现行技术标准给出的有架空地线线路档距中央导—地线最小间距计算经验公式为S=0.012L+1,该公式生成过程并未考虑10 kV架空线路情况，不宜简单套用到10 kV线路上。笔者采用仿真模拟计算方法，建立了雷电直击10 kV线路架空地线档距中央瞬态过程计算模型，经大量雷电过电压计算比较研究，确定了仿真关键线路参数和取值。基于档距中央耐雷水平指标，计算获得了通用系列档距下的导—地线间距值，供工程设计人员参考。为简化工程操作，进一步提出了对技术标准经验公式的修正公式为S=0.034L+0.04。

Jianzhu Gangjiegou Jinzhan, 2021 为探究Q690高强钢梁火灾后的破坏模式和承载性能,对6根经历650℃高温加载后自然冷却的Q690高强钢梁进行了试验研究。试验结果表明,残余变形对火灾后Q690钢梁的破坏模式和极限承载力均有显著影响;Q690高强钢加热到650℃后自然冷却,其材料性能几乎无变化,仅屈服强度略有降低。在试验的基础上,建立有限元模型并完成校准,进行大规模参数分析,拟合得到火灾后高强钢梁的整体失稳承载力计算公式。拟合公式与规范计算结果和试验数据的对比表明,提出的公式具有足够的精度、合理性和安全性。

Beyond Universalism: A Contextual Approach to Comparative Public Administration
Public Administration and Development, EarlyView.ABSTRACT In this essay, I advocate for a contextual approach to comparative public administration, arguing that effective governance reform requires moving away from universal models to embrace local political, socioeconomic, and institutional realities.

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery
Conservation Biology, EarlyView.Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT What are the conditions under which business corporations expand their institutional power? This paper argues that institutional power is affected by the architecture of the “acquisition regime”—the set of formal (and informal) rules that govern how states purchase public services.

Dehydrogenation Thermodynamic and Kinetic Challenges of Mg‐Ni‐Based Alloy Hydrides
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Solid‐state hydrogen storage stands as a pivotal, safe, and efficient solution for the future hydrogen economy. Among diverse hydrogen storage systems, Mg‐Ni‐based alloy hydrides are recognized as cornerstone materials. However, their practical application is hindered by two core challenges: the high thermodynamic stability of the hydride ...

Home‐Based Versus In‐Hospital Care in Pediatrics: A Systematic Review of Cost‐Effectiveness Studies
World Medical &Health Policy, Volume 18, Issue 2, June 2026.ABSTRACT Home‐based care has emerged as a potential alternative to traditional hospital‐based care for children and adolescents worldwide. This systematic review aimed to systematically gather and critically assess the available evidence on the cost‐effectiveness of home‐based versus in‐hospital care for pediatric populations globally.

Gaoya dianqi, 2016 根据污闪事故发生时的环境监测数据,大气环境污染及其污染性质也是影响输变电设备外绝缘表面污秽程度的因素,而污染物粒径较小的地区积污增长速度较大。因此,针对某些学者提出的理论盐密值与大气环境参数间的经验公式,提出了纳入PM2.5后的经验公式修正建议。分别根据纳入PM2.5的经验公式和未纳入PM2.5的经验公式,计算了理论盐密值,并与安装在监测点附近的光传感器盐密在线监测装置的实测数据进行了对比分析。利用纳入PM2.5后的经验公式的ESDD理论计算值与实际值较为吻合,而未纳入PM2 ...

Queer Reconstruction: Smiling Queers and the Making of 2SLGBTQI+ Identity in Canada
Sexuality, Gender &Policy, Volume 9, Issue 2, May 2026.ABSTRACT The legalization of same‐sex marriage in 2005 signaled a new relationship between queer people and the Canadian state. Governments and queer communities moved from contention to collaboration, framing queerness through pride and celebration.
