面心立方过渡金属自扩散的改进分析型嵌入原子法分析
Analysis of Self-Diffusion of FCC Transition Metals by Modified Analytical Embedded-Atom Method
 [PDF]

Abstract:

采用改进分析型嵌入原子法(MAEAM)计算了面心立方过渡金属Ni、Pd、Pt、Cu、Ag、Au和Al自扩散过程中的能量。对于最近邻(NN)和次近邻(NNN)二种扩散机制,其能量曲线均为对称曲线且能量的最大值均位于各自扩散路径的中点。计算得到的单空位形成能、迁移能和自扩散激活能比用嵌入原子法(EAM)计算的结果更接近NN扩散的实验数据。计算结果表明NN扩散的激活能最低(迁移能也为最低),因此面心立方过渡金属中的最可几扩散为单空位最近邻扩散。
The energy during the process of self-diffusion in FCC transition metals Ni, Pd, Pt, Cu, Ag, Au and Al has been calculated by using modified analytic embedded-atom method (MAEAM). For each kind of two diffusion mechanisms nearest-neighbor (NN) and next-nearest-neighbor (NNN), the energy curve is symmetric and the maximum value of the energy appears at the middle point of the diffusion path. Determined mono-vacancy formation energy , migration energy and activation energy for self-diffusion agree well with available experimental data of NN diffusion and are better than those obtained by the embedded-atom method (EAM). Compared the energies corresponding to two diffusion mechanisms, the NN diffusion needs the lowest activation energy (and thus the lowest migration energy). So that, the NN mono-vacancy diffusion is favorable in FCC transition metals.

我国“新型城镇化”建设应避免六个方面的认识误区

农业现代化研究 , 2013,
Abstract: 针对近年我国的“粗放式城镇化”建设问题,本文从“城镇化”不等于都市化、舍弃乡村、造城镇、抛弃传统、无差异、同路径六个方面,梳理城镇化建设的常见认识误区;并提出我国“新型城镇化”建设应因地制宜合理规划,统筹考虑大中小城市并举;乡村与城镇共生共赢、乡村文明与城镇文明共存共荣;人民生活质量和素质能力的提升;传统文化与现代文明的高度融合;继承当地历史文脉,延续地区特质和民族个性;根据各地的区位条件,走多元化的城镇化道路。

Abstract:

随着全球环境日渐恶化,环境意识与绿色消费已成为国际议题。本研究透过文献整理探讨中国消费者在环境意识、绿色态度与绿色消费行为之间的关系,以及内外部环境影响和阻碍因素,并归纳与推导研究主张与概念图。最后,本文在借鉴国外经验和结合中国实际情况的基础上,提出中国绿色消费行为的推行建议与管理意涵。
As the global environment is deteriorating, environmental conscious and green consumption have become an international issue. Through the literature review, this research explores the relationships among the environmental conscious, green attitude and green consumer behavior in China, as well as internal and external environmental impacts and consumption constraints, and concludes with the propositions and concept framework. Finally, this research provides the improvement suggestions and managerial implications based on the actual situation in China and combined with foreign experience.

康艾注射液对Ⅲ,IV期非小细胞肺癌放疗增效减毒作用的临床观察
,
中国中药杂志 , 2006,
Abstract: 肺癌中的80%为非小细胞肺癌(NSCLC),其中70%为中晚期肺癌。中晚期肺癌患者往往选择放化疗等治疗手段,患者在放疗中常伴有免疫功能低下、生存质量差等症状。在肿瘤治疗的同时,如何改善患者免疫功能状况及生存质量,延长生存期,同时降低正常组织的放射损伤对临床意义重大。本科应用康艾注射液配合放射治疗Ⅲ,Ⅳ期非小细胞肺癌,发现康艾注射液既能增加肺癌的放疗疗效,又能减轻放疗不良反应。1一般资料1.1病例选择标准①依据《新编常....
学术期刊影响因子修正——基于期刊学科综合性及网络发行视角
,
图书情报工作 , 2009,
Abstract: ?指出学术期刊的学科综合性使同类期刊刊发论文存在学科差异;学术期刊实现网络发行后,学术期刊引文密度和引文时间正发生持续动态变化。认为现行的学术期刊影响因子计算方法及修正方案不能很好地反映以上两种情形,导致影响因子出现偏差。提出从学术期刊学科综合性和网络发行视角对影响因子进行修正,使之能准确体现学术期刊学术影响力,从而对我国的学术期刊进行真实、客观、公正的评价。
协商民主在城中村治理中的价值与实践

,
- , 2015,
Abstract: 城市化加速发展和社会结构深刻变化,使城中村及村转居社区治理面临许多新挑战。一方面,该区域各种社会矛盾和社会问题呈集中多发态势,另一方面,城中村居民自主管理、民主法制意识和利益诉求在不断提升,而基层政府管理体制和工作方法却存在诸多不适应的地方,致使社区治理绩效难以达致理想状态。因此,探寻政府行政管理和基层群众自治衔接互动的最佳结合点,成为理论和实践的难题。协商民主在很大程度上适应了城中村治理中实现政府与村(居)民良性互动的要求,同时也为城市基层治理提供了有效的利益整合机制、公共参与机制和协商沟通机制。鉴于目前基层协商机制运行尚处于实践探索阶段,故应着力于协商民主制度的完善和协商主体能力的培养,以切实推动城中村社会治理改革创新。
The accelerated development of city and the profound changes in social structure make the villages inside cities and the community governance face many new challenges. On the one hand, various social contradictions and social problems in the region are concentrated and of multiple trend.On the other hand, the independent management, the democratic and legal consciousness and interest demand of the residents are rising, while the local government management system and working methods have many unsuitable points,which makes the community governance performance difficult to achieve the ideal state.Therefore,to explore the best combination of interface interaction between government administrative management and grassroots mass autonomy has been a difficult problem in both theory and practice. Deliberative democracy largely not only meets the demand of benign interaction between government and villagers in governance of villages inside cites,but also provides the mechanism of interests integration,effective public participation mechanism and negotiation mechanism for the grassroots governance of the city.With the current operation of grassroots negotiation mechanism still in the exploratory stage,we should focus on the improvement of deliberative democracy system and the cultivation of the ability of the deliberative body so as to effectively promote the reform and innovation of society governance of villages inside cities.
R&D投入能力、企业特征、政府作用与企业低碳生产意愿研究
,,吴林海
科技进步与对策 , 2010,
Abstract: 以江苏苏南地区的212家工业出口企业为例,基于二元Logistic模型,研究了工业出口企业低碳生产意愿与主要影响因素。研究表明,78.8%的工业出口企业具有低碳生产意愿,而企业的R&D投入能力、销售规模、管理者年龄、所有制性质等企业特征,强制性的制度安排与政策体系等外部因素与低碳生产的现实意愿具有显著的正相关性,验证了目前国外研究结论对中国工业出口企业基本具有普遍的适用性。虽然是以出口工业企业为案例,但由于出口工业企业的层次总体高于非出口企业,其研究结论在较高的层次上揭示了影响工业企业低碳生产现实意愿的主要因素,因而具有一定的普遍意义。R&D投入能力企业特征政府作用工业企业低碳生产意愿
