Testing the QNSE scheme with the modified coefficients of turbulent mixing length scale: Three summer and autumn coastal gale cases study in China(用调整边界层湍流系数的QNSE方案模拟夏秋季沿海大风的应用研究)

Zhejiang Daxue xuebao. Lixue ban, 2018
利用WRF模式，采用YSU、QNSE边界层参数化方案以及调整参数后的QNSE边界层参数化方案(MQNSE),对2009年7月梅雨个例、2015年苏迪罗台风以及2013年10月的近海大风进行了模拟试验，并对模拟结果进行对比检验，着重检验参数调整后的QNSE方案模拟沿海大风效果.研究结果如下：参数调整后的QNSE 边界层参数化方法改进了对沿海风场的模拟效果，尤其是当风速小幅脉动时，参数调整后的QNSE方案较接近于实况风速的波动.通过登陆台风个例模拟试验和对沿海10个岛屿观测站的490个样本统计检验表明 ...

Machine Learning‐Driven Discovery and Experimental Validation of Effective Precursor Additives in Perovskite Solar Cells

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.

Revealing the Roles of Electrolyte Concentration on Transition Metal Dissolution and Reaction Pathway of Anion Adsorption Pseudocapacitance

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Conventional lithium‐ion battery cathodes predominantly rely on reversible lithium intercalation in bulk, which inevitably induces phase transitions, transition metal migration, and voltage decay. Electrolytic anion adsorption pseudocapacitance provides a chance for bypassing these issues via a surface‐dominated reaction, especially in ...

Dual‐Layer Solid Electrolyte Interphase Enables Effective Suppression of Lithium Dendrites

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The heterogeneous solid electrolyte interphase (SEI) at the Li metal anode often leads to slow and uneven Li+ flux, causing severe Li dendrite growth. Herein, we combine X‐ray photoelectron spectroscopy and cryogenic transmission electron microscopy to demonstrate that a dual‐layer SEI, consisting of an inorganic inner layer and an organic ...

现场变压器油色谱数据的统计分布规律

Gaoya dianqi, 2018
整理了广东地区和华北地区的现场电力变压器实测色谱数据,根据数据特点选择相应的抽样方法,获得了各气体参量的数据样本。运用统计学中的非参数统计的方法对样本数据进行非参数检验,检验结果是各气体参量基本服从对数正态分布或者韦伯分布,同时获得了各气体参量所服从的各分布的分布函数以及相应的90%及95%分位点注意值。其中95%分位点注意值比国标和IEC中给出的气体参量注意值小,从而减少了对变压器故障的漏判。

Flexible, Robust Transparent Conductive Films With Excellent Electromagnetic Shielding Properties

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Transparent conductive films (TCFs) are indispensable components for next‐generation wearable electronics, intelligent robots, and electromagnetic interference (EMI) shielding devices. However, the fabrication of conventional random metallic mesh suffers from an inherent trade‐off between “randomness and controllability”.

The Formation and Hardening Mechanisms of Multiscale Gradient Structures Tailoring by Explosive Hardening and Annealing in Commercially Pure Titanium

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Gradient structures (GS) introduced by plastic deformation have been shown to effectively enhance the surface properties of metallic materials. However, the GS fabricated by existing methods often suffers from limited hardening depth and limited control over the GS layer, which constrain their engineering applications.
