Performance of biomaterials was strongly affected by their surface properties and could be designed artificially to meet specific biomedical requirements. In this study, F(F), Si O2 4(Si), or HCO 3(C)-doped Ca–P coatings were fabricated by biomimetic deposition on the surface of biodegradable high-purity magnesium(HP Mg). The crystalline phases, morphologies and compositions of Ca–P coatings had been characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM) and energy-dispersive spectroscopy(EDS). The biomineralization and corrosion resistance of doped Ca–P coatings had also been investigated. The results showed that the Ca–P coating with or without doped elements mainly contained the plate-like dicalcium phosphate dehydrate(DCPD) phase. The doped F, Si, or C changed the surface morphology of Ca–P coatings after mineralization. Doped F enhanced the mineralization of Ca–P coating, and doped Si retarded the mineralization of Ca–P ***, H2 evolution of HP Mg discs with different Ca–P coatings was close to 0.4–0.7 ml/cm2 after two-week immersion. That meant that the corrosion resistance of the Ca–P coatings with different or without doped elements did not change significantly.

在接触网输电导线选型和负荷调度过程中接触网允许载流量是需要考虑的关键因素,而允许载流量的大小与接触网所处的地理气候条件密切相关。该文首先提出考虑接触网沿线的风速、风向、环境温度、海拔高度以及太阳有效入射角度等地理气候因素的单根输电导线的允许载流量计算方法;在此基础上利用接触网输电导线电流分配关系和接触网综合载流量的概念提出接触网综合载流量的计算方法;进而提出了接触网的动态增容方法,该方法通过接触网所处位置的地理气候参数动态计算接触网的载流能力。算例表明:输电导线及接触网载流量在不同地理气候条件下相差较大;接触网设计过程中接触网综合载流量应根据接触网所处地区夏季气候参数进行计算;输电导线容量利用率可判断所选择输电导线的匹配程度;利用动态增容技术可以大幅提高接触网载流能力。该研究成果对牵引网输电导线选型、负荷调度具有一定借鉴意义。

一、强相互作用物理学采用还原论和演生论两种思想,研究大至宇宙、小至基本粒子等一切物质最基本的运动形式和规律,以及由这些规律所支撑的各种自然现象。强相互作用是人们认识到的四种基本相互作用之一。在质子和中子等强子的典型尺度下,它的典型大小约为电磁相互作用的102倍、弱相互作用的105倍和引力相互作用的1039倍。量子色动力学(QCD)理论是描述强相互作用的标准理论,它指出组成强子的基本结构单元即夸克,通过胶子传递相互作用。
