加强大学生社会主义核心价值观培育的思考——以古代中国“化民成俗”生活教化实践为视角

古代中国"化民成俗"是通过改变物质生活方式从而达到构建满足封建统治阶级意愿的社会精神秩序的生活教化实践。其体现出来生活化、渐进性、综合性的教化特征不仅是我国传统教育的要义,也是现代教育的应有之义。社会主义核心价值观作为符合中国具体国情的主流价值需要社会的接受和认同,对"化民成俗"的研究为新的社会精神秩序的构建特别是对大学生对主流价值的接受和认同提供了新的视角。在遵循大学生认知发展规律的基础上,通过与大学生生活的全面对接,实现社会主义核心价值观的协同培育。古代中国"化民成俗"生活教化实践为大学生社会主义核心价值观培育点明了思路。

自律协同的智能电网能量管理系统家族:概念、体系架构和示例

能量管理系统(EMS)通过信息流调控能量流,保障电网运行的安全高效,被公认为电网运行的"大脑"。随着智能电网的快速发展,传统集中式EMS已难以满足海量信息处理和快速控制决策的需要,为此提出了自律协同的智能电网EMS家族的概念和分布式架构,涵盖了智能电网源、网、荷三大环节的各部分。家族成员内部实现自律,家族成员之间实现协同。分析了家族成员的共性和个性,介绍了若干EMS家族新成员,例如:风电场EMS、变电站EMS和电动车集群EMS。EMS家族成员之间通过互联协调,形成面向整个电力系统的源—网—荷协同的EMS家族网络,支撑整个智能电网的安全高效运行。介绍了若干EMS家族成员协同的示例,如输—配协同、站—中心协同和风—车协同。     

烟气污染物协同治理中的负协同效应串联作用现象

随着烟气污染物协同治理技术在燃煤电站的普遍应用,协同治理过程中各单元设备间的不良影响及其造成的设备治理能力下降或污染物增量排放现象日益显现,对此类负协同效应展开分析,并通过性能试验、检测化验、运行诊断等方法对某350 MW机组进行研究,结果表明：存在负协同效应串联作用现象,即上游设备的负协同效应不断蚕食本体或下游设备的污染物治理能力,最终导致设备治理能力不足。最后,提出控制及消纳负协同效应的建议。

Characterizing the catalyst fluidization with field synergy to improve the amine absorption for CO_2 capture

There are great interests to capture the CO_2 to control the greenhouse gas emission. Amine absorption of CO_2 is being taken as an effective way to capture CO_2 in industry. However, the amine absorption of CO_2 is cost-ineffective due to great energy consumption and solution consumption. In order to reduce the capture cost, catalyst fluidization is proposed here to intensify the mass transfer and heat transfer. Catalyst fluidization with field synergy and DFT model is developed by incorporating the effects of catalyst reaction kinetics, drag force and multi-field into the mass transfer, heat transfer, fluid flow and catalyst collision. Experiments with an improved distributor are performed well to validate the model. The reaction kinetics is determined by the DFT simulation and experiment. The mass transfer coefficient in the fluidized reactor is identified as 17% higher than the conventional packed reactor. With the field synergy of catalyst fluidization, the energy consumption for CO_2 desorption is reduced by 9%. Stepwise operation and inclination reactor are used to improve catalyst fluidization process.     

有序涡旋对三角槽道脉动流强化传热的影响

以水为工质对三角槽道内单相液体充分发展层流脉动传热特性进行了研究。应用粒子图像测速技术（PIV）测得流场内涡的变化规律,从“涡及涡运动”的角度揭示了“有序”的涡生长及迁移过程对脉动流强化传热的影响。此外,应用“场协同”理论,通过数值模拟深入分析了流场特性与传热之间的关系。研究发现,“有序”的涡生长及迁移过程,破坏了流体边界层,促进了近壁区热流场与速度场的协同,同时,强化了三角槽道内流体与主流区流体的掺混,热量输运能力提升;存在最佳的Strouhal数（St）,使得涡旋既能充分发展又能在较短时间脱落进入主流,实现最大效率的壁面换热;有序涡旋对速度场、温度梯度场以及压力梯度场三者协同性的改善是换热性能提升的关键。

Standardized low-load repetitive work: evidence of different motor control strategies between experienced workers and a reference group

The purpose of this laboratory study was to evaluate the possible differences in motor strategies to a new standardized low-load repetitive work task in between healthy experienced workers and a reference group. Work task event duration, i.e. working rhythm, cutting forces, surface electromyographic (EMG) activity from four shoulder muscles, postural activity, and arm and trunk movements in 3D were recorded during low-load repetitive work simulation. The experienced group showed lower EMG activity and frequency contents (P<0.05), more abducted position of the upper arm and forward flexion of the trunk prior to work simulation (P<0.05), and increased arm and trunk range of motion (P<0.05) compared with the reference group. The results highlight that experienced butchers have a different motor strategy compared with a reference group, i.e. more variable form of coordination pattern. Furthermore, the initial implementation of a possible protective motor strategy by experienced workers might be a very important prognostic factor.
