Gaoya dianqi, 1992 根据测量系统等效电路的传递函数的幅频特性图,优化设计了CT线圈测量系统和外被电极测量系统,CT线圈测量系统有一个较好的频率选择特性,有一个可以减少外界干扰的谐振频率,当第一个谐振点频率约为100kHz时,CT线圈测量系统的测量灵敏度为2～10pC,外被电极测量系统的灵敏度为15～30pC,应用这两种测量系统,对充有SF6或SF6/N2或SF6/空气混合气体且带有固定微粒或自由微粒的同轴电极系统,获得了一些检测局部放电的结果。

Emerging applications of large language models in ecology and conservation science
Conservation Biology, EarlyView.Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study
International Journal of Applied Linguistics, EarlyView.ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.

There Is Always a Bigger Fish. Determinants of Power Perceptions in Swiss Biodiversity Policy
Policy Studies Journal, EarlyView.ABSTRACT The Advocacy Coalition Framework (ACF) views power as crucial in policy processes, but the nature of coalition power, its determinants, and how to empirically measure it remain understudied. In this article, we use a mixed method approach and social network analysis to explore power relationships in the biodiversity policy subsystem in ...

Gaoya dianqi, 2015 文中建立了用于高压电缆的温度在线监测的光纤传感系统,针对电缆不同部分的测量需求,采用不同的光纤传感原理分别进行了温度测量。通过模拟电缆隧道进行了有针对性的试验,试验结果表明,布里渊温度测量系统的精度可达2℃,布里渊散射频率与温度变化呈严格的线性关系;拉曼温度测量系统的精度可达0.5℃;拉曼温度测量系统适用于通过监测热点温升电缆局部缺陷;布里渊温度测量系统适用于电缆全段的温度测量,实现动态载流量;点式光纤光栅温度测量需要注意消除电缆温度变化导致形变的干扰。

Emotion and the Advocacy Coalition Framework: An Affective Dynamics Perspective
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Despite extensive evidence that emotion and cognition are deeply intertwined, the Advocacy Coalition Framework (ACF) lacks an analytically independent emotional mechanism in its causal architecture—an omission that may be particularly consequential in policy subsystems structured around morally charged, identity‐laden policy disputes.
