Dianci bileiqi, 2021 雷电冲击电压波形正确与否对于雷电冲击电压试验的有效进行至关重要。本研究利用EMTP软件搭建接入变压器后的四阶雷电冲击电压试验回路,分析波头电阻选取对波前时间和峰值过冲系数的影响。讨论将四阶系统电路简化为三阶电路时变压器等效电感和电阻选取的限值。针对波头电阻选取存在的困难,分析阻尼装置对电压波形参数调整的作用。研究结果表明:波头电阻的增加能够有效抑制雷电冲击电压波形的振荡,降低峰值过冲系数;当且仅当回路内部电感和负荷电容都较小时,存在波头电阻选择区间使得波前时间和过冲系数同时满足标准要求 ...

Wildlife Letters, Volume 3, Issue 4, Page 194-202, December 2025.This study establishes the optimal nonlethal laser deterrence range (210–260 W, 1s) for wild boars, preventing agricultural damage while ensuring animal safety. Results demonstrate that efficacy requires seasonal power adjustments (≤ 285 W in winter) and precise targeting control—enabling effective, injury‐free wildlife conflict mitigation.

Environmental racism and air pollution: Pre and post the COVID‐19 economic shutdown
Review of Policy Research, Volume 42, Issue 4, Page 949-981, July 2025.Abstract Decades of research demonstrates that minoritized groups are disproportionately affected by swathes of harmful pollutants, including air pollution, even controlling for low income. Would significantly reducing individual car traffic help reduce the EJ gap?

Dianci bileiqi, 2013 冲击时间间隔和冲击次数直接影响石墨-陶瓷电阻的电压系数。研究表明:冲击间隔时间为10 s时电阻阻值变化幅度较小,电压系数较低,即最佳冲击间隔时间为10 s;随着冲击次数的增加,电阻的电压系数趋于常值,最佳冲击次数为100次。
