| 1 | 用纳米压痕法分析溶剂对聚醚醚酮(PEEK)力学性能的影响(英文)显示文摘本文采用纳米压痕分析方法研究丙酮对聚醚醚酮(PEEK)在不同的暴露时间的表面力学性能的影响.实验以恒定加载速率(/mbox10nm/s)以及到最大压痕位移(1000nm)条件下进行.以压痕硬度和弹性模量作为连续刚性模式压痕中穿透位移的连续函数.实验数据显示,随着溶剂环境中PEEK暴露时间从0增加到18天,峰值的载量从-5.2mN降低到-1.7mN.PEEK样品的弹性模量和硬度也随溶剂环境中暴露时间的变化而呈下降趋势.采用两个经验模型拟台硬度随着暴露时间变化的函数,与实验值显示出很好的一致性. | Tanveer Iqbal Saima Yasin Ahmad Shakeel Hamayoun Mahmood Fahad Nazir Paul F.

| 2 | Study of pure and semileptonic decays of D_s meson within R-parity violating supersymmetric model显示文摘We present the comaprative study of semileptonic and leptonic decays of Ds, D±and D0meson(D →M l+-αl-β, D → l+αlβ, D → l+αvα;α,β=e,μ) within the framework of R-parity violating the( Rp) Minimal Supersymmetric Standard Model(MSSM). The comparison shows that combination and product couplings,(λβiαλ* ij qor λβqkλ*αj k)contribution to the branching fractions of the said processes(under consideration) is consistent with or comparable to the experimental measurements in most of the cases. However, some cases exist where these contributions are highly suppressed. We identify such cases in our analysis and single out the important ones suitable for exploring in the future and current experiments. | Farida Tahir Azeem Mir Shakeel Mahmood | 2014 | Chinese Physics C2014，38，12： | 0 |
