磁刺激促进骨折愈合及对血液生化参数的影响(英文)

对１２０例新鲜骨折患者进行了磁刺激对骨折愈合和多种血液生化参数影响的试验研究,分析了磁刺激促进骨折愈合的作用机理．对比试验结果表明：磁刺激可促进钙盐沉着,加强人体的钙磷代谢,从而加速骨折的愈合过程．     

层次分析法在《绩效管理》课程的教学思路及案例解析

《绩效管理》课程是人力资源管理专业的专业核心课程之一,该课程的重点内容是利用定性和定量方法对组织内的人员进行绩效考核与评价。由于此部分内容涉及较多的统计学的综合评价分析原理及步骤,在教学过程中师生普遍反映有一定的难度。究其原因,主要在于学生未能将综合评价分析方法与绩效考核流程相结合。文章归纳总结了综合评价方法在绩效考核课程的运用思路,其中关键点是构建评价指标体系和估算权重,并通过案例展示了层次分析法(AHP)在绩效考核中的教学思路及步骤以便于教学。     

基于课程群的电子信息工程创新实验体系改革探索

科技服务业集聚化发展关键影响因素识别研究——基于直觉模糊层次分析法

在对科技服务业集聚化发展的本质进行深入剖析基础上,提出科技服务业产业集聚区实质为协同创新生态网络的子网络。基于协同创新生态网络的影响视角,结合已有文献的解析,从政府、外部环境、内部环境3个维度提取影响科技服务业集聚化发展的因素,增加创新网络的影响因素,采用直觉模糊层次分析法对所有影响因素进行权重确定。以西安市为例,得到影响其科技服务业集聚化发展因素的重要度排序,其中宏观政策环境因素的影响最为关键,其次为区域产学研协同创新网络的科技创新能力和科技服务中介机构的协同能力。最后提出完善政府支撑政策、提高区域产学研协同创新网络的科技创新能力和建立高端科技服务聚集区等推进科技服务业集聚化发展的政策建议,为我国城市发展科技服务业专业化、全面覆盖科技创新产业链条的集聚化发展提供参考。     

Aesthetic experiences in the Cerrado (Brazilian savanna): contributions to environmental education practice and research

In this paper, we reflect on a study in Brazil’s Cerrado that attempts to address a lack of attention to an aesthetic dimension in environmental education practice and research. We start by tracing this lack to the overvaluing of the cognitive sphere in the educational process, noting its echo in the low aesthetic value attributed to the Cerrado biome. Then, through reflecting on an empirical, interview based study of sensations, perceptions and feelings evoked by aesthetic experiences in the Cerrado, we draw on insights from a hermeneutic phenomenological approach to identify key themes for environmental education research and practice in this regard. These include: recognising the singularity of experience; attending to the qualities of experience; acknowledging the value/s of ‘lighter’ and ‘darker’ experiences; and deepening emotions and verbal communication. In our final considerations, we discuss the limitations of the study, alongside new directions in studies of perception, experience, aesthetics and pedagogy that may also advance attention to an aesthetic dimension in environmental education practice and research.     

A pilot scale trickling filter with pebble gravel as media and its performance to remove chemical oxygen demand from synthetic brewery wastewater

Evaluating the performance of a biotrickling filter for the treatment of wastewaters produced by a company manufacturing beer was the aim of this study. A pilot scale trickling filter filled with gravel was used as the experimental biofilter. Pilot scale plant experiments were made to evaluate the performance of the trickling filter aerobic and anaerobic biofilm systems for removal of chemical oxygen demand (COD) and nutrients from synthetic brewery wastewater. Performance evaluation data of the trickling filter were generated under different experimental conditions. The trickling filter had an average efficiency of (86.81±6.95)% as the hydraulic loading rate increased from 4.0 to 6.4 m³/(m²·d). Various COD concentrations were used to adjust organic loading rates from 1.5 to 4.5 kg COD/(m³·d). An average COD removal efficiency of (85.10±6.40)% was achieved in all wastewater concentrations at a hydraulic loading of 6.4 m³/(m²·d). The results lead to a design organic load of 1.5 kg COD/(m³·d) to reach an effluent COD in the range of 50–120 mg/L. As can be concluded from the results of this study, organic substances in brewery wastewater can be handled in a cost-effective and environmentally friendly manner using the gravel-filled trickling filter.

Q-代数的区间值（α^~,β^~]-模糊子代数

模糊区间值与区间值模糊集的重于关系概念被考虑,这种关系是模糊点与模糊集的重于关系的推广.利用这种新的思想,引入了Q-代数的区间值（∈,∈∨q）-模糊子代数和区间值（∈,∈∨q-）-模糊子代数的概念,推广了Q-代数的模糊子代数,并研究了它们的相关性质.特别地,界限模糊子群之概念被扩展到Q-代数的界限区间值模糊子代数的概念上来.     

南宋高宗建炎年间御营司及御营五军研究

建炎元年五月,为重整军权,南宋王朝设立了御营司和御营五军。作为最高军事指挥机构,御营司直辖御营五军的体制打破了自宋初以来"枢密院调兵,三衙掌兵"的传统;但作为强化对全国军队尤其是行在部队控制的措施,御营司未能完成其使命,它存在4年即遭废罢。
