丙烷选择氧化催化剂AgMoO_2PO_4·MoO_3相协同效应研究 [PDF]
, 2001 借助催化剂反应性能的评价、XRD、H2 TPR、ESR和XPS技术考察了丙烷选择氧化催化剂AgMoO2 PO4 ·MoO3中AgMoO2 PO4 和MoO3 两相间的协同效应。结果表明 ,两相间的协同效应导致AgMoO2 PO4 ·MoO3 具有高的丙烷选择氧化性能。协同效应是由于在两相间产生“一致性界面”的缘故。“一致性界面”的生成有利于各物种在AgMoO2 PO4 和MoO3 两相间发生扩散 ,从而在催化剂表面生成“分立”的氧化中心。因此 ,在AgMoO2 PO4 ·MoO3 ...

, 2011 企业间协同与价值创造一直是学者们探讨的焦点。本文在波特和伊丹广之研究的基础上围绕着企业间协同创造价值的本质,企业间协同成功的前提条件两个问题进行研究,认为企业间组合效应除了互补效应和协同效应外还应包括集束效应。企业间价值创造的本质是在集群效应或是知识衍生效应下的规模收益。而且协同共享是有成本的 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The deformation behavior of NiTiNb shape memory alloys is governed by microstructural heterogeneity, specifically the interconnected topology of the β‐Nb phase. The regulatory role of the eutectic structure in load partitioning and the evolution of deformation mechanisms, particularly in high‐Nb systems, has not been clearly understood.

四川大学学报. 自然科学版, 2013 自动信任协商是为了解决开放网络环境中陌生实体很难建立信任关系的问题而提出的一种新安全解决方案.本文提出了一种新的信任协商模型,即一种自适应自动信任协商模型AATN,该模型可根据用户的信任度对访问控制策略进行调整,实现了对不同信任度的用户采用不同的访问控制策略,从而在保护隐私的同时提高了信任协商的效率.本文主要分析了自适应信任协商模型的模型框架、自适应协商策略和一致性校验器等关键技术,并通过实验证明了AATN模型能够有效兼顾信任协商中效率和安全两方面的需求.
