The Effect of Heat Treatment on Mechanical Properties of Cu-0.93 mass％Ni-0.24 mass％P Alloy [PDF]
, 2019 Cu-Ni-P alloys are the typical precipitation-hardening material. Thus, Cu-Ni-P alloys are expected to apply alternative materials for heat-exchanger tubes.

Jianzhu Gangjiegou Jinzhan, 2021 为了研究部分包裹混凝土组合(PEC)柱(弱轴)与型钢梁对穿高强螺栓端板连接节点的抗震性能,考虑端板厚度、盖板厚度以及节点构造形式3个参数,设计了两种不同构造的梁柱节点,对其进行低周往复荷载试验和有限元模拟,分析了各设计参数对试验节点滞回性能、承载能力、节点刚度、延性和耗能能力等指标的影响。研究结果表明:盖板厚度由14mm增加至16mm时,节点承载力提高了33.91%,初始刚度提高了14.9%,延性降低了18.9%;端板厚度由12mm增加至14mm时,节点承载力提高了19.93%,初始刚度提高了15.1%,

Zhongguo cuzhong zazhi, 2022 院前延迟是急性缺血性卒中患者错过再灌注治疗时机的主要原因，常因患者不合理的就医行为决策导致。既往研究多探讨就医延迟、转运延迟等外在影响因素，较少从患者自身决策的角度进行院前延迟的分析。本文从缺血性卒中患者就医行为决策的概念、现状及其影响因素这3个方面进行总结，分析目前急性缺血性卒中患者就医行为决策中存在的问题，讨论认知、环境、心理等因素对患者就医行为决策的影响及原因，为制订针对性的干预措施提供参考。 Abstract: Pre-hospital delay is the main cause ...

Journal of Linguistic Anthropology, Volume 36, Issue 1, May 2026.Abstract Native speakerism in English language teaching (ELT) has become associated with Whiteness. However, how this association is sustained in everyday practices within China's unique socio‐cultural‐political context remains underexplored. This study examines the raciolinguistic construct of Mubai, a central recruitment criterion in China's ELT ...

Jianzhu Gangjiegou Jinzhan, 2018 为研究低屈服点钢材LY100在反复拉力作用下的力学性能,设计LY100钢与Q345钢或Q235钢焊接连接的材性试件,共进行4组18个材性试件的单调和反复受拉加载试验研究。获得6种不同加载制度下试件的荷载-位移曲线、应力-应变曲线、滞回性能、超低周疲劳破坏机理以及延性特征等。研究结果表明,焊接接头对试件的超低周疲劳性能有不利影响,焊接接头使LY100钢材力学性能的稳定性和延性变差;LY100钢与Q345钢或Q235钢焊接后,材性试件的强度提高但延性下降;反复拉力作用下,带有焊接接头的材性试件呈现强度硬化 ...
