Generalized LHSS method for non-Hermitian positive definite linear systems(求解非埃尔米特正定方程组的广义LHSS迭代法)
Zhejiang Daxue xuebao. Lixue ban, 2018 基于矩阵的埃尔米特和反埃尔米特分解，李良等给出了一类求解非埃尔米特正定方程组的LHSS迭代法，在系数矩阵的埃尔米特和非埃尔米特之间进行了非对称迭代，在较松弛的约束条件下即可获得收敛结果.本文对该方法做进一步研究，给出了一类求解非埃尔米特正定方程组的广义LHSS迭代方法.数值结果表明，系数矩阵经恰当分解，在处理某些问题时广义LHSS迭代法优于HSS迭代法.

Rare Metals, EarlyView.ABSTRACT The high accuracy in surface‐enhanced Raman scattering‐lateral flow immunoassays (SERS–LFIAs) is critical for reliable point‐of‐care testing (POCT) in clinical diagnostics. Conventional approaches are often affected by sampling variability and uneven distribution of immunoprobes, leading to unreliable signal fluctuations.

Rare Metals, EarlyView.ABSTRACT Organic‐inorganic metal halide perovskite solar cells (PSCs) are promising for photovoltaics due to their excellent optoelectronic properties. However, achieving high efficiency and stability remains challenging, mainly due to defects and energy losses at the electron transport layer (ETL)/perovskite interface.

Rare Metals, EarlyView.ABSTRACT Early detection of thermal runaway (TR) is essential for lithium‐ion battery (LIB) safety, as unchecked TR risks catastrophic failures in energy storage systems. Gas‐based sensing offers a faster and more direct approach by detecting decomposition products at the molecular level.

Dizhen xuebao以饱和两相介质土力学模型为基础，建立了一维P波和S波波动的动力方程组。针对该动力方程组，采用伽辽金加权余量法进行空间离散，之后采用中心差分法与纽马克（Newmark）线性加速度法（γ＝1/2，β＝1/6）相结合的时间步进法进行时间离散，得到了求解有限元动力方程的全显式时域逐步积分公式。接着结合透射人工边界求解饱和两相介质近场波动问题，并用内源波动和外源散射两个数值算例对该算法的合理性进行了验证。其中：内源波动算例是将一维柱体在阶跃荷载和正弦荷载作用下的数值解与相应的解析解进行对比，二者计算结果基本一致 ...

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
Rare Metals, EarlyView.ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.

Rare Metals, EarlyView.ABSTRACT Single‐atom catalysis hinges on fundamental challenges in precisely controlling metal‐support interactions and rationally regulating metal–adsorbate relationships. Herein, we report a universal strategy for constructing highly efficient and well‐defined Cu(I) single‐atom catalysts based on a trifurcate AlL3 molecular support.

齿轮可靠度计算的概率有限元法（第Ⅱ部分:齿面接触疲劳强度的计算）
Jixie chuandong, 1993 本文将概率有限元法用于齿轮接触疲劳强度可靠度的计算。以功率、转速和疲劳极限为随机变量,在求解接触问题的有限元—线性规划法基础上,建立了相应的概率有限元基本方程及求解方法。该方法不仅可用于齿轮接触疲劳的可靠度计算,也可用于其他弹性体接触问题的可靠度计算。

Rare Metals, EarlyView.ABSTRACT Efficient and durable bifunctional electrocatalysts are vital for scalable water electrolysis. Here, we realize cobalt‐vacancy (Covac) engineering in CoFeP supported on N,P‐codoped carbon nanocages (Co1‐vacFeP/NPC) through a simple route comprising a CoFe Prussian blue analog precursor, phosphidation–pyrolysis, tannic‐acid etching, and a ...
