金华市婺城区发展茶业循环经济的路径分析

本文阐述循环经济的理念在茶业生产中的应用。资源节约利用,产业持续发展和环境保护是区别传统茶业生产与循环农业模式的主要因素。金华市婺城区良好的气候条件、良种茶园的建设成果、茶叶生产加工机械化的普及改良和茶业标准化、组织化建设为发展茶业循环经济创造了有利的条件,但传统茶业生产根源的广泛性和循环经济意识的缺乏、及相应的支撑体系不完善也制约了茶业循环经济的发展。加大宣传,提高循环经济意识,加强循环茶业技术支撑和成熟模式的示范推广,完善保障体系,是推动茶业循环经济发展的重要途径。     

Analysis of workload of tank crew under the conditions of informatization

A consensus has been reached that the tanks need to be integrated into the informatization battlefield. With the development of technology, the tank crew has being gradually decreased, so the research on two-soldier crew tank has become a hotspot. The workload of tank crew under the conditions of informatization is analyzed based on the combat mission of tank and the typical combat scenarios, and the impact of new technologies on workload is evaluated. The crew members in tank can be reduced from three to two, but it is necessary to substantially improve the automation of target search and the reliability of each subsystem and component.     

民办高校开放性实验室网上预约管理系统的开发

高校实验室是人才培养的基地。民办高校实验室开放是提高办学水平,增加学生的动手能力,更能充分利用了实验室的资源,提高了民办高校实验室及仪器设备的利用率,为大学生创新能力的培养和教师科研水平的提高,提供了良好的环境;但传统的手工实验管理已很难满足现代实验教学的要求。为此,开发了一套开放性实验管理系统,旨在实现实验室资源、实验课程的有效管理以及提供预约实验的可能。应用数据库技术,设计并实现了一个基于Web的应用——开放性实验管理系统。     

Formation mechanism of periodic layered structure in Ni3Si/Zn system

The formation of periodic layered structure in Ni₃Si/Zn diffusion couples with Zn in vapor or liquid state was investigated by SEM-EDS, FESEM and XRD. The results show that the diffusion path in solid–liquid reaction is Ni₃Si/(T+γ)/γ/…T/γ/Ni₄Zn₁₂Si₃/γ/…Ni₄Zn₁₂Si₃/γ/Ni₄Zn₁₂Si₃/δ…/Ni₄Zn₁₂Si₃/δ/liquid-Zn, and the diffusion path in solid–vapor reaction is Ni₃Si/θ/(T+γ)/γ/…/T/γ/…T/γ/vapor-Zn. With increasing Zn diffusion flux, the diffusion reaction path moves toward the Zn-rich direction, and the distance from the Ni₃Si substrate to the periodic layer pair nearest to the interface decreases. In the initial stage of both reactions, γ phase nucleates and grows within T matrix phase at first, and then conjuncts together to form a band to reduce the surface energy. Based on the experimental results and diffusion kinetics analysis, the microstructure differences were compared and the formation mechanism of the periodic layered structure in Ni₃Si/Zn system was discussed.
