1跨境电商实践教学存在的问题及未来发展趋势显示文摘实践教学作为跨境电商人才培养的重要组成部分,对创新型、复合型、应用型、国际型人才的培养发挥着重要的作用。对跨境电商实践教学存在的现状进行分析,指出当前跨境电商实践教学存在实战不可行、模拟有局限和实践需深化三个方面的问题。同时,结合对跨境电商行业的理解,指出跨境电商实践教学分为以平台模拟为主要特征的1.0阶段、以综合训练为主要特征的2.0阶段、以数据化运营为主要特征的3.0阶段以及以数据化的全面融入为主要特征的4.0阶段。当前跨境电商实践教学总体上处于3.0阶段,并提出在可预见的跨境电商实践教学4.0阶段,数据将和课程全面融合,跨境电商知识体系将被重构,并对院校人才培养产生深远影响。邹益民 Gerasimov Ruslan Zhang Xiaocan 2021对外经贸2021,,2:10
2Al2O3-TiC/Q235真空扩散钎焊界面组织及抗剪强度显示文摘为了获得Al2O3-TiC陶瓷基复合材料与Q235钢的接头,采用Ti/Cu/Ti复合中间层对Al2O3-TiC复合材料与Q235低碳钢进行了真空扩散钎焊。通过扫描电镜、能谱分析和电子探针、抗剪试验等测试方法对Al2O3-TiC/Q235扩散钎焊界面的组织、成分及结合强度进行分析。结果表明,控制加热温度为1110℃,可获得界面抗剪强度122MPa的Al2O3-TiC/Q235扩散钎焊接头,Ti/Cu/Ti复合中间层与Al2O3-TiC和Q235润湿性较好,并发生一定程度的扩散反应,在Al2O3-TiC与Q235之间形成厚度约80μm的界面过渡区,过渡区内形成的组织结构主要是Ti3AlC2,Fe2Ti,Cu和TiC。王娟 李亚江 S.

9A correlation between structural changes in a Ni-Cu catalyst during decomposition of ethylene/ammonia mixture and properties of nitrogen-doped carbon nanofibers显示文摘Changes of a 65Ni25Cu10Al2O3 catalyst consisting of Ni-enriched and Cu-enriched alloys were investigated in the bulk and on the surface during the growth of nitrogen-doped carbon nanofibers (N-CNFs) by decomposition of a 50%C 2H4 /50%NH3 mixture using in situ X-ray diffraction (XRD) analysis, ex situ X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM) techniques. It was shown that N-CNF growth at 450 650 C is accompanied by dissolution of carbon and nitrogen in the Ni-enriched alloy, whereas Cu-enriched alloy remains inactive. A correlation between nickel and copper surface concentrations and properties of N-CNFs in relation to the nitrogen content was found. It was demonstrated that phase composition of the catalyst during N-CNF growth determines the type of N-CNFs structure.O. Yu. Podyacheva A. N. Shmakov A. I. Boronin L. S. Kibis S. V. Koscheev E. Yu.
