基于Relief特征量优化及SOM网络的断路器操作机构状态评估
Gaoya dianqi, 2017 为提高断路器操作机构状态评估的效率及准确性,文中提出了采用Relief优化方法对分合闸线圈电流特征向量进行优化及SOM网络对线圈电流样本进行分类的高压断路器操作机构状态评估方法。仿真研究结果表明:基于Relief的分合闸线圈电流特征向量优化方法和SOM网络分类方法的操作机构状态评估能够实现操作机构状态的准确评估,同时采用优化后的电流特征向量数据进行状态评估减小了运算量和缩短了运算时间,提高了断路器机构状态评估的效率。

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Rationally selection of precursor additives during perovskite crystallization is essential for obtaining high‐quality films and achieving high‐performance perovskite solar cells (PSCs). However, the discovery and optimization of effective additives still rely heavily on time‐consuming and costly trial‐and‐error experiments.

Gaoya dianqi, 2018 综合考虑复合绝缘子在运行中表现出来的各种老化特性,客观评估其老化程度是保障复合绝缘子安全运行的关键。为此,提出一种复合绝缘子的老化评估模型,将复合绝缘子试品的外观检查试验、憎水性试验、红外测温试验结果作为评估模型的输入参数,对复合绝缘子试品进行老化评估,发现2号复合绝缘子老化程度最重,建议退出运行;1号复合绝缘子老化程度最轻;而3号复合绝缘子老化程度一般,需要跟踪监测。最后通过扫描电镜试验和傅里叶红外光谱试验,验证了评估结果的正确性,说明文中提出的评估模型对于复合绝缘子的老化评估具有一定的意义。

VO2 Hollow Nano‐Reactor: Enabling Near‐Room‐Temperature and Ultrafast Hydrogen Release From α‐AlH3
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT α‐phase aluminum trihydride (α‐AlH3) is a promising high‐capacity hydrogen storage material, but its practical application is limited by slow dehydrogenation kinetics and high reaction temperatures. This study demonstrates, for the first time, effective modulation of the hydrogen release kinetics of AlH3 by employing a hollow nanostructured ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Currently, the photocatalytic performance of ZnO has been severely limited by its weak light response ability and sluggish charge carrier dynamics, which considerably hinder its extensive application in photocatalytic fields. Herein, through anchoring the synthesized K6PMo11FeO40·nH2O (PMo11Fe) onto ZnO nanosheets, a novel S‐scheme ...

Hybrid Flexible–Soft Neural Interface as a Practical Solution for Long‐Term Implants
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Implantable neural interfaces face persistent challenges in long‐term functionality due to chronic immune responses, mechanical mismatch with tissue, and material corrosion in vivo. The commonly used flexible materials, such as polyimide and parylene‐C (poly[monochloro‐p‐xylylene]), have advantages in low water vapor permeability and high ...
