Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Managing diabetic wounds requires simultaneously addressing their infectious, oxidative, and regenerative impairments. To address this, this study integrates a piezoelectric BiOCl@CuSe heterojunction (PFM‐verified) into an injectable F127/HA hydrogel, creating an ultrasound‐responsive smart dressing.

, 2010 有机分子实际上是生命体死亡后的产物,本身不具有“生长发育“与“衰亡解体“过程,而生命分子则是生命体不可分割的一部分或一个环节,本身在元素原子或分子递换传输或化学反应链中复制繁殖、分裂分化、生长发育 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The inherent brittleness of hardmetals stems from the rigid covalent bond in the ceramic matrix and the sharp ceramic/metal interface, which restricts the nucleation and motion of dislocations. In this study, a novel strategy is proposed to activate significant dislocation behaviors in the WC matrix by employing a non‐equiatomic CoNiFeCr ...

Jianzhu Gangjiegou Jinzhan, 2023 为提高整体式桥的梁台结合部抗裂性能与施工便利性，提出一种新型整体式桥台与组合梁结合部构造。采用ABAQUS通用分析软件，考虑钢混界面摩擦滑移效应，建立整体式桥台与组合梁结合部的三维有限元模型。通过仿真计算得到整体式桥台与组合梁结合部的破坏形态与荷载-挠度曲线，分析其极限承载力与传力机理，并与模型试验结果进行对照验证。进一步通过参数化计算分析，得到混凝土强度、钢材强度、钢板厚度与腹板形式对梁台结合部承载性能的影响。研究结果可为整体式桥梁及类似结构的研究提供参考。

A Study on Risk Management of Currency Composition of China’s Foreign Exchange Reserves [PDF]
, 2011 新世纪以来，我国经济和外汇储备规模持续快速增长。截至2010年末，我国外汇储备余额为28473亿美元，远超日本、英国等传统的外汇储备主要持有国，外汇储备总规模居世界第一。然而，持续高速增长的外汇储备和长期以来我国的货币组合配置也带来了巨大的管理成本和风险。当前，美国次贷危机引发的全球经济危机阴霾尚未散去，欧洲主权债务危机继续蔓延，美元及其他主要国际储备货币存在着长期贬值预期。在此大环境下，对外汇储备的货币组合即币种结构的影响因素进行合理分析，对存在的风险进行合理有效的识别及管理 ...

Verification and Reduction of Web Service Composition Based on Petri-Net [PDF]
, 2005 近年来Web服务的理论和技术取得了长足的发展,其保证互操作性的协议栈下层在学术界和工业界已基本达成一致.然而Web服务的价值在于服务重用,新兴的Web服务组合正是主要的重用手段。然而基于流程的Web服务组合建模是一个复杂且易出错的过程。如果流程定义在投入运行之后被发现有错，则修复错误的代价相当高，因此，在建模阶段进行有效的过程验证时十分必要的。此外Web服务组合可能存在不必要的流程设计而影响执行效率。本课题提出一个基于Petri网的Web服务组合验证及简化方法，此方法包含建模、验证、简化三个阶段 ...
