Dianci bileiqi, 2023 目前传统的高光谱污秽检测主要针对人工涂污样本。而运行复合绝缘子由于结构和自然积污复杂、基材浸污严重，难以运用其方法进行污秽检测。因此搭建了适用于绝缘子污秽检测的高光谱拍摄平台，并提出了一种基于高光谱的运行复合绝缘子污秽检测技术。首先，针对绝缘子光谱特性，提出了一种基于噪声学习的一维卷积降噪自动编码器(1D-RDCAE)高光谱数据转换方法，消除不同拍摄情况导致的谱线偏移现象。其次通过核主成分(KPCA)提取不同污秽程度的光谱特征；分别建立基于线性判别算法(LDA)、BP神经网络(BPNN)以及极限学习机 ...

Overreliance on Orthographic Similarity in L2‐Japanese Conceptual Processing by L1‐Chinese Learners
International Journal of Applied Linguistics, Volume 36, Issue 2, Page 1807-1820, May 2026.ABSTRACT Orthographic and phonological similarities between first (L1) and second (L2) languages can facilitate L2 processing. Particularly, L1‐Chinese learners of L2‐Japanese can benefit from the shared morphosyllabic Chinese characters (Japanese kanji/Chinese hanzi) because of their similar orthographies.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Metal oxide‐based catalysts for oxygen reduction reaction (ORR) have drawn great attention in recent years. However, it remains technically challenging for the precise regulation of the overall performance due to the trade‐off effect among the activity, selectivity, and stability of electrocatalysts. Herein, a balancing strategy to control the

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Lightweight and lead‐free radiation shielding materials remain urgently needed. This work designed a fluorite high‐entropy oxide (FHEO) system through a combined computational–experimental route. Density functional theory based on special quasi‐random structures was used to identify thermodynamically stable fluorites from a wide compositional ...
