    这篇文章在以往对效率与公平问题研究成果的基础上,探究邓小平经济伦理思想中所蕴涵的解决这一经济伦理困境的思路和办法。 全文共分四章,第一章论述我国改革开放前后我国在处理经济效益与社会公平问题上误区及困境,针对这一困境,邓小平提出了解决经济伦理困境的一个卓越的思想——坚持经济效益与社会公平的辩证统一。接下来的主体部分第二章、第三章是对这一思想的具体阐述,首先论述了邓小平关于经济效益与社会公平的辩证统一思想具体表现的三个方面:经济效益与社会公平的同时性平衡、整体性平衡和历时性平衡。其次论述的是经济效益与社会公平平衡机制的具体应用。邓小平在谈到如何处理经济规律与价值取向、公有制与非公有制、市场配置与...Based on research findings about the problem of efficiency and fairness, Teng Hsiao-ping’s economic ethics which contains solutions to the dilemmas of economic ethics will be discussed in this paper. This article contains four chapters. In chapter one, misunderstanding and dilemmas people came acrossed around the reform and opening will be examined. Thus this paper holds that Teng Hsiao-ping’s...学位:哲学硕士院系专业:人文学院哲学系_马克思主义哲学学号:1042007115269

    摘 要: [目的/意义] 开放科研数据面临着科研人员参与度和认同度不高的挑战。文章旨在明确科研人员开放科 研数据的行为影响因素,为各利益相关者更好地激励科研人员参与实践提供参考。 [方法/过程] 研究基于计划行为理论建立模型,探究行为信念、行为态度、主观规范和感知行为控制对地球科学领域科研人员开放科研数据行为的影响; 通过问卷调查收集数据,采用偏最小二乘法结构方程模型 ( PLS-SEM) 工具 SmartPLS3. 0 分析数据验证模型。[结果/结论] 地球科学领域科研人员对开放科研数据态度直接显著影响行为; 行为信念 ( 包含感知职业利益与感知职业风险) 、感知行为控制 ( 包含感知数据基础设施和数据管理培训实用性) 显著影响科研人员的态度,且通过态度间接影响行为; 主观规范对科研人员的态度影响不明显,但对行为存在显著影响。 &nbsp; Abstract: [Purpose / significance] Open research data faces the challenge of researchers' skepticism and low participation. To find out the motivational factors that influence researchers' open research data behaviors can help stakeholders better encourage re searchers' participation. [Method/ process]Based on the theory of planned behavior,a research model was established to explore how behavioral beliefs,attitudes,subjective norms,perceived behavioral control influence earth science researchers' open research data behaviors. A questionnaire survey was conducted to collect data,partial least squares structural equation modeling (PLS-SEM) tool SmartPLS3. 0 was used to analyze the data and verify the research model. [Result /conclusion] The results show that earth sci ence researchers' attitudes toward open research data significantly influence their actual behaviors. Behavioral beliefs (including the perceived career benefit and risk) and perceived behavior control ( including the perceived available of data infrastructure and the perceived available of data management training) have significant influence on their attitudes,through which indirectly influence the actual behaviors. Subjective norms have significant influence on behaviors,but no influence on attitudes. &nbsp; </div

    Corresponding author e-mail:zhuangquanchao@ 126.com[中文文摘]电极界面特性是影响锂离子电池充放电循环容量与稳定性的重要因素。本文总结了目前对电极界面特性进行研究的方法,主要包括传统的电化学方法、显微方法、谱学方法、电化学石英微晶天平等,重点论述了上述研究方法的原理、优缺点和在研究电极界面特性中的应用,以及这些方法相结合所取得的一些研究进展,并指出在今后的工作中,无论是对新材料的研究还是传统材料的研究,这些方法都仍将发挥重要作用。[英文文摘]The rechargeable lithium-ion battery has been extensively used in mobile communication and portable instruments due to its many advantages,such as high volumetric and gravimetric energy density and low self-discharge rate.In addition,it is the most promising candidate as the power source for(hybrid) electric vehicles and stationary energy storage.The properties of electrode /electrolyte interfaces play an important role in the electrochemical performance of the electrode material and a battery,such as the capacities,irreversible charge “loss”,rate capability and cyclability. In present paper,the methods to investigate the properties of electrode/electrolyte interfaces,for example, traditional electrochemical methods, microscopy methods, spectroscopic methods,electrochemical quartz crystal microgravimetry (EQCM) are summarized. The principles,advantages and disadvantages of these methods and their applications in investigating the properties of electrode/electrolyte interfaces,especially the progress in the combination of these methods to investigate the properties of electrode/electrolyte interfaces,are introduced in detail,and these methods will be considerable to study the new materials or the traditional materials for lithium-ion batteries in the future.中央高校基本科研业务费专项资金项目(No.2010LKHX03,2010QNB04,2010QNB05);中国矿业大学科技攀登计划(No.ON090237),中国矿业大学青年科技基金项目(No.ON080282)资
