Research and simulation of resonant earthed system Based on IPC [PDF]
, 2008 我国中压配电网，绝大多数采用中性点不接地方式。这种接地方式最大的优点是:当发生单相接地时，三相线电压的对称性没有被破坏，所以用户用电不受影响，可维持一定长的时间。但是，当配电网达到一定规模，对地电容电流达到一定数值后，必须采取加装消弧线圈的措施来保证配电网的安全。 配电网中性点采用消弧线圈接地的方式，对于改善电网供电质量、提高供电可靠性和保证整个系统安全运行都有十分重要的意义。本文在此背景下，对谐振接地系统展开研究与仿真。首先介绍了中性点接地方式的发展过程，通过对谐振接地原理和单相接地故障的分析 ...

Conservation Biology, EarlyView.Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

A more‐than‐human political ecology of Indonesian songbird trade
Conservation Biology, EarlyView.Abstract Since its inception, conservation science has considered wildlife trade a problem. In focusing on conservation outcomes, conservationists almost completely ignore the welfare of traded animals and plants and the harms they endure. We developed a political ecology approach that incorporates the interconnectedness of people with animals and ...

International Journal of Applied Linguistics, Volume 36, Issue 1, Page 522-539, February 2026.ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.
