Effect of obstacles fixed in two parallel plates on the diffusion of polymer chain(平行板内障碍物对高分子链扩散的影响)

Zhejiang Daxue xuebao. Lixue ban, 2011
采用分子动力学(MD)方法研究了高分子单链受限在2块不可穿透的平行板之间且平行板内有均匀分布的障碍物时的扩散行为.模拟结果发现：分子链的链长N及障碍物间距d对高分子链扩散系数D影响很大.链越长（N越大），扩散越慢（D越小）；同时障碍物间距d越小，扩散越慢（D越小）.障碍物对高分子链的形状因子及链大小也有影响.障碍物间距d越小时，高分子链更接近棒状，链尺寸也较大.这些研究结果有助于全面了解高分子链在受限环境下的构象及动力学过程.

Microstructure Tailoring of Laser Powder Bed Fused Nb521 Alloy Toward Strength‐Ductility Synergy

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Niobium‐based refractory alloys are promising candidates for high‐temperature aerospace structures, yet their limited ambient‐temperature ductility and poor processability remain major barriers to broader implementation. Here, Nb521 alloy was fabricated by laser powder bed fusion (LPBF), and the effects of processing conditions and subsequent ...

基于级联光纤光栅的透射色散补偿

Guangtongxin yanjiu, 2004
分析了光纤光栅的色散特性,介绍了利用均匀光纤光栅透射色散特性进行色散补偿的原理,对级联光纤光栅用于波分复用（WDM）系统多信道色散补偿进行了数值模拟和分析.结果表明,通过选择适当的光纤光栅参数,级联光栅能够对WDM系统中由于常规光纤而色散展宽的光脉冲进行有效的色散补偿.

Dual‐Bioactive Lignin‐Based Microcarrier Hydrogel Platform via Metal Salt Crosslinking for Synchronized Infection Eradication and Bone Regeneration

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Infected bone defects represent a dual therapeutic challenge demanding concurrent infection inhibition and osteogenesis promotion. Systemic antibiotic administration is taken as a classical treatment protocol but often yields inadequate local antibiotic concentrations and delayed bone repair.

氯化钙在10X分子筛上的单层分散研究

四川大学学报. 自然科学版, 2007
根据盐在载体上自发单层分散的理论,通过样品的XRD检测分析,研究了不同担载方法、担载量和焙烧温度对氯化钙在10X分子筛上单层分散的影响.在担载量同为0.6 g/g时,乙醇溶液浸渍样品在500℃下焙烧,氯化钙即能达到完全单层分散;水溶液浸渍样品须在550℃的焙烧温度下氯化钙才能达到完全单层分散,并且出现了明显的离子交换.干混法样品的氯化钙单层分散量显著低于乙醇溶液浸渍法和水溶液浸渍法,在600℃下其氯化钙担载量既使从0.6 g/g降低至0.4 g/g,仍然有显著的氯化钙晶相峰存在 ...

In Situ Preparation of Ti2Ni/NiTi Dual‐Phase Alloy With High Wear Resistance and Damping Performance by Additive Manufacturing

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Many metallic components are frequently subjected to coupled environments of friction and vibration, stemming from interfacial contact and relative motion between mating parts or external stimuli. Consequently, it is imperative for these components to exhibit a synergy of high wear resistance and superior damping properties.
