BTA和PTD对铜的缓蚀作用的光电响应研究

用光电化学方法研究了铜电极在含缓蚀剂ＢＴＡ和ＰＴＤ的硼砂和硼砂－硼酸缓冲溶液中的光电化学行为,研究了不同浓度缓蚀剂对铜电极表面Ｃｕ２Ｏ完全还原为Ｃｕ的电位φＶ的影响,试验结果表明φＶ表征了缓蚀剂所形成的膜与Ｃｕ２Ｏ怪之间的结合力,缓蚀作用越强则φＶ越负。     

The Enriched UTAUT Model for the Acceptance of Software Engineering Tools in Academic Education

This article provides an enriched technology acceptance model explaining the impact of both classic and additional variables on software engineering tools acceptance within Information Systems Development courses. Two novel, domain-specific variables were identified (i.e., Professional Training Diffusion and Model Interchange). Statistical verification of the proposed model and study regarding the influence of the variables on students’ intention to use specific tools were conducted—providing users with enhanced means of selecting optimal software for real-life projects.     

Fifty years of high frequency diffraction

The study of high frequency diffraction phenomena mostly associated with geometrical theory of diffraction, uniform theory of diffraction, physical theory of diffraction, and their alternatives is reviewed. Several examples illustrate these theories and their applications in antennas and scattering problems. © 2013 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2013.     

低频超声辐射对融合蛋白PTD-SOD渗透离体皮肤的影响

通过小鼠的离体皮肤渗透,研究了低频超声(40 kHz)辐射对融合了蛋白转导域的超氧化物歧化酶(Proteintransduction domain-superoxide dismutase,PTD-SOD)体外经皮渗透的影响.结果表明,透皮8h时,低频超声与氮酮(Azone)的增渗比分别为3.40和2.52;低频超声作...     

背腔式微带天线电磁散射分析的FEM/PO-PTD方法

将一种新的混合方法-FEM/PO-PTD方法，应用于分析计算背腔式微带天线的电磁散射特性。通过无穷大接地导体平面上矩形背腔式微带天线的RCS计算，验证了该方法的正确性。在此基础上，计算了两组有限尺寸金属载体上背腔式微带天线的RCS曲线，理论分析与计算结果表明，该混合方法具有计算机内存需求少、计算时间短等优点。
