Gaoya dianqi, 2014 针对固体环网柜绝缘在线监测问题,提出一种综合在线监测方案,同时监测母线温升、泄漏电流值和介质损耗值来反映固体环网柜绝缘状态。针对母线温升监测,采用取能电流互感器、温度传感器以及红外传输方式的配合,解决了对母线电连接处温升测量隔离的难题。同时监测泄漏电流值和介质损耗值,二者相结合作为绝缘状态的判据,并通过老化实验验证了各项参数判据值大小选取的合理性。最后,通过现场在线产品的测量表明,该装置满足测量的准确度和稳定性的要求,为固体环网柜绝缘在线监测提供参考。

Ecology and Evolution, Volume 15, Issue 10, October 2025.This paper proposes a ‘relaxed’ point‐count survey method to enhance accessibility and expand geographic coverage by easing these constraints. Surveys can be conducted in diverse locations, including urban areas and travel routes, within flexible timeframes (e.g., 6 h after sunrise or during the evening) and with adaptable spacing between survey points,

Impact of race‐based customization on detection of fetal growth restriction
Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 4, Page 480-485, October 2025.ABSTRACT Objective Fetal growth standards determine which fetuses are diagnosed with fetal growth restriction (FGR) and become candidates for enhanced fetal monitoring. Given the existence of race‐based differences in fetal and neonatal weights, we sought to determine the impact of race‐based customization of fetal growth curves on the antenatal ...
