全固态电池界面的研究进展

采用固态电解质代替有机电解液的全固态电池具有高能量密度和高安全性等优点,为下一代能量存储设备提供了一种很有发展前途的解决方案。然而,大多数固态电解质和电极活性物质间都存在严重的界面问题,制约固态电池的实际应用;解决固态电池中的固-固界面问题,提升固态电池电化学性能是目前的研究热点。本文详细总结了固态电池中的界面挑战、改善策略以及针对界面问题的表征方法,并展望了固态电池今后发展中的关键方向和趋势。

The Fuzzy Grey Relational Analysis of the Factors Influencing Farm Produce Logistics

The farm produce logistics plays an important role in promoting the agricultural production and prosperity of the rural economy,so grasping the main factors influencing the development of farm produce logistics,is of important significance to accelerating the development of farm produce logistics. The values of identification coefficient in the grey relational analysis are taken based on the experience,so the accuracy of the results is affected. This article uses the improved fuzzy grey relational analysis to analyze the main factors influencing farm produce logistics. The results show that the number of storage companies has a great impact on the development of farm produce logistics,followed by the farm produce processing machinery capacity,rural transport infrastructure,farm produce market conditions and government financial support for agriculture,while the total number of Internet users in rural areas has an limited impact on the development of farm produce logistics.

高绩效工作系统对抑制性建言的影响研究:工会实践的调节作用

高绩效工作系统对抑制性建言的促进作用已得到证实,然而,其中的作用机制并未充分探讨。本文从资源保存理论出发,以情感承诺、心理安全为中介变量,工会实践为调节变量,探讨高绩效工作系统影响抑制性建言的内在机制,并以371名企业工会成员为样本,运用SPSS 22.0和Mplus 7.4进行统计检验。结果显示:(1)情感承诺和心理安全在高绩效工作系统与抑制性建言之间起中介作用;(2)工会实践正向调节了高绩效工作系统与情感承诺以及高绩效工作系统与心理安全之间的关系,进一步发现,工会实践水平越高,心理安全的中介作用越强,但工会实践对情感承诺的中介作用的影响并不显著。本文从资源保存理论的视角为激发员工抑制性建言提供了一个新的途径,同时也为促进工会实践与企业人力资源管理实践协同发展提供有力依据。
