基于高职院校辅导员工作的创业就业指导工作模式探究

政府出台并落实了一系列大学生创业就业扶持政策,提出了推进创新创业教育和自主创业工作的重要工作部署,创业就业相关指导课程已全面开展,但是,在快速发展的过程中难免存在一些不足。而且近年来,高职院校人才培养质量大不如前,社会认可度呈下降趋势,高职院校学生在创业就业过程中存在很多困难和问题。本文以辅导员日常工作为基础,将创业就业指导工作融合其中,充分发挥纽带作用,实现创业就业教育贯穿大学生步入社会前最后成长的每一个阶段,为学生顺利创业就业提供帮助。     

Optimal Extended Warranty Policies under Different Maintenance Options

Extended warranty has recently obtained increasing attention from both manufacturers and customers in China. In this paper,given the reality of China, two types of non-renewing extended warranty were proposed： one-dimensional extended warranty and two-dimensional extended warranty. And a combined warranty policy including pro-rata warranty policy and free-repair warranty policy was applied in these two types of warranty. Then the expected life-cycle cost models from the manufacturer and consumer＇s perspectives were developed considering different maintenance options. The optimal warranty policy, maintenance options,and warranty price were adopted in terms of a win-win interval which was determined by the maximum extra cost the consumer should pay and the minimum price the manufacture should sell at the extended warranty. Finally,a case study was given to prove the effectiveness and validity of the model.     

Equipment Maintenance Mode Based on Network Environment

Aimed at the actuality of Peoplep’s Liberation Army(PLA) army equipment maintenance, this paper develops equipment maintenance mode based on network,and focuses on the design of maintenance decision-making system. Analyzing maintenance weight is applied to making decision of repair level.The purpose of the research is introducing basic concept and setting up an equipment maintenance mode using military network.Maintenance mode based on network can reduce the costs,enhance the maintenance efficiency, and save the human resource and finance.     

物相调控对铌酸钠纳米棒压电-弱可见光协同催化的优化作用

半导体材料能够吸收光能产生电子空穴对,利用光催化实现环境废物降解,然而其催化效率受环境光条件和天气等因素严重制约。因此,有必要研发能够利用环境中的水波能和光能协同作用的催化剂,以有效提升水相环境的污染物降解效率。无铅钙钛矿结构的铌酸钠具有适宜的能隙和压电性能,因此具备实现光-压电协同催化的潜力。通过水热法合成并调控了铌酸钠纳米棒的物相结构,探究了其对光-压电协同催化中的性能增强机制。虽然两种物相的铌酸钠光催化效率差异较小,但相较NaNbO₃,Na₇(H₃O)Nb₆O₁₉14(H₂O)表现出更高的压电性能,因此在压电光催化过程中能够更好地促进光生电子空穴对的分离,从而大幅提升了水中四环素的降解效率。进一步对材料物相调控方法、催化机理等开展研究,揭示了空穴和羟基自由基在催化过程中起到关键作用,研究结果能够为高效光-压电协同催化剂的设计、开发和优化提供参考。
