Gaoya dianqi, 2021 较之实验室人为模拟的缺陷试品而言,选用实际的含缺陷的GIS绝缘子进行实验研究更能够反映变电站现场的局部放电情况,并更为真实地模拟现场闪络事故的产生过程。但是实际绝缘子上所含的缺陷通常是未知的,因而需要先对缺陷在绝缘子上的位置进行示踪,以了解缺陷的具体形式,为后续的进一步的研究提供基础。文中以一个含有未知缺陷的GIS支柱绝缘子为例,通过光电效应、红外成像、不同气体条件下的放电特性变化等多种手段尝试示踪缺陷的具体位置,最终通过高精度断层扫描确定了缺陷的具体形式 ...

Numerical Simulation And Experiment Study On Magnetoacoustic Emission with Magnetic Induction [PDF]
, 2015 铝合金板材具有高强度、低密度、强耐腐蚀、高断裂韧性和良好的高低温特性等优点，是制造宇宙飞船、运载火箭、飞机、舰船、坦克、装甲车和高速列车的主要材料。然而，由于加工工艺限制，铝合金板材在生产过程中不可避免地存在分层、夹杂、裂纹和氧化膜等缺陷。无损检测技术是一种在不破坏待测物材质与性能前提下实现构件质量检测的技术，目前已在许多领域成为确保产品质量和可靠性的强制性措施。 本文研究的感应式磁声发射无损检测方法是利用线圈在导体感应出的涡流在静态磁场的作用下会受到洛仑兹力的作用使导体发生机械振动，进而产生磁声信号 ...

Leveraging an Unhappiness Lens for Smarter Policies
Policy Studies Journal, EarlyView.ABSTRACT Traditional policy research has largely focused on enhancing happiness or well‐being, privileging positive outcomes as the primary metric of success. We argue that a systematic focus on the drivers of unhappiness—rather than solely on happiness—offers a complementary analytical framework that can uncover hidden societal deficits and broaden ...

Safety Assessment and Research of the Thermal Power Generation Enterprise in the Pipeline [PDF]
, 2015 由于历史原因，大部分火力发电企业的压力管道在施工及使用过程中均没有有效的监管和检验，有些管道都有可能“带病”运行，严重威胁了企业的生产安全和电网稳定。因此，摸清火力发电企业在用压力管道的实际安全状况，对企业、社会都有着重要意义。 本文以福建某火力发电企业在用天然气管道为研究对象，探索在不停机及短暂停机状态下选择合适的检测技术快速准确的查出安全隐患，同时对含超标缺陷的管道进行安全性评价，以帮助企业在不影响正常生产、保障电网稳定的前提下根据缺陷危害程度合理安排检修时间 ...

The Research on Steel Plate Defects Inspection by Magneto-acoustic Testing with Induction [PDF]
, 2015 随着工业化的发展，钢材被应用在了各种各样的领域，比如：天然气管道、轮船、汽车等等。然而，随着时间的推移，钢材在使用过程中会出现腐蚀、裂纹等缺陷，这些缺陷严重影响了使用的安全，所以必须在事故发生之前对其进行检测以评估其安全性。本文在对比多种无损检测方法及研究感应式磁声成像的基础上提出了感应式磁声检测的新方法。该方法是在静态磁场下，通过脉冲电流激励被测钢板表面，进而在钢板内部发生电－磁－声的相互转化，最后提取钢板表面的磁声信号。该方法与被测材料无接触，无耦合，可在恶劣环境下进行工作，非常适合钢板的在线检测。

Overreliance on Orthographic Similarity in L2‐Japanese Conceptual Processing by L1‐Chinese Learners
International Journal of Applied Linguistics, Volume 36, Issue 2, Page 1807-1820, May 2026.ABSTRACT Orthographic and phonological similarities between first (L1) and second (L2) languages can facilitate L2 processing. Particularly, L1‐Chinese learners of L2‐Japanese can benefit from the shared morphosyllabic Chinese characters (Japanese kanji/Chinese hanzi) because of their similar orthographies.
