结构变化、效率改进与浙江省能源需求预测

结合浙江省当前阶段性经济发展和能源消费特征,运用部门分析法,在对各终端部分经济活动水平及能源强度情景分析的基础上,对浙江省2015-2030年能源需求进行预测.综合各种情景结果,2015年浙江省能源需求总量的区间约为2.03～2.23亿吨标准煤,能源强度下降18％,2030年浙江省能源需求总量将达到约3.1亿吨标准煤,单位GDP能耗约为0.41吨标煤/万元.     

民族地区课程资源再开发存在的问题与对策

早在2001年,教育部颁布的《基础教育课程改革纲要（试行）》中就明确提出了＂积极开发并合理利用校内外各种课程资源。＂并且新全日制义务教育各学科课程标准中都设有＂课程资源的开发与利用＂一项。伴随着我国基础教育新课程改革的深入,课程资源再开发的重要性也愈发的凸显出来。     

Where is the “theory” within the field of educational technology research?

Critics often characterise the study of educational technology as under-theorised. To test this assertion and to determine the extent of this criticism, the present paper reports an in-depth analysis of the 503 most recent empirical articles published in three selected education-technology-related journals (Computers & Education; Learning, Media and Technology; and British Journal of Educational Technology). These journals were selected because they publish studies related to all education settings rather than focusing on only a certain segment such as higher education; they have broad geographical catchment; and they were the most highly ranked journals in terms of their 2017 journal citation impact factor. The present paper examines how explicitly existing theory was identified in previous research, how theories were applied and how often these theories were advanced in education technology research. In the majority of cases, explicit engagement with theory was absent. Many studies either were wholly bereft of theories or made vague use of theory. Where theory was explicit, the articles were more likely to use theory to conceptualise the research, to inform the data collection or analysis process and to discuss the results. Very few articles reported findings that help us to learn something new about a particular theory (ie, little evidence of theory advancement).     

基于交变磁场的水管防垢试验研究

利用麦克斯韦方程和边界条件,计算了交变磁场在水管中的场分布.采用交变磁场的磁感应强度作为参量,用试验的方法得到水管结垢量与磁感应强度之间的关系,从而提出了结垢磁感应强度阈值的概念.结果表明,水的硬度在小于700 mg/L的范围内,不同的管径对应的结垢磁感应强度阈值相近.此外,还对水的参数如温度、硬度、流速与结垢量的关系进行了试验研究.

高放苏联剧变研究评析

高放同志能站在邓小平理论的高度,根据我们党在“文革”后拨乱反正和改革开放中发展了的马克思主义来重新认识和研究长期影响苏共思想政治路线的“左”和右的问题。高放同志能抓住事物的主要矛盾,梳理和归纳出苏联模式社会主义社会长期存在的三大矛盾,从这三个主要矛盾中去寻找导致苏联剧变的深刻原因。第一大矛盾是过“左”的路线和过度集权的党政领导体制同社会主义社会要求尽快发展生产力、发展民主与自由的矛盾。第二个大矛盾就是党政军官僚高薪特权集团同人民大众的矛盾。第三个大矛盾是大俄罗斯主义势力同各族人民的矛盾。高放同志研究苏联剧变问题的另一个特色是能从历史根源上寻找和分析斯大林社会主义模式的弊病。高放同志能着眼于从党的领导制度和组织制度问题上寻找苏共作为一个政党遭到失败的根本教训。     

Decomposing apparent power and losses in distribution systems with nonlinear loads

The definition of reactive power for non-sinusoidal conditions is a controversial issue. The mathematical treatment of nonlinear loads in power systems is also unsettled. This paper starts with the decomposing of apparent power in,the cases of linear and nonlinear loads. When harmonics are present, apparent power is composed of active power, reactive power, and disturbed reactive power. Linear element can be defined as the element without disturbed reactive power. This definition is based on a practical engineering concept which can separate the contribution from the apparent power into utility-duty part and custom-duty part. The field investigation of home-used facilities was conducted. Also the data acquisition in the 0.4 kV distribution systems was completed. Moreover, the loss increase due to the nonlinear loads was estimated. Nonlinear loads can be a dominant effect with respect to reactive power and power factor. Field data from a number of nonlinear load types indicate that the disturbed reactive power can cause significant losses in utility supply systems.

危机事件中互联网"圈子"用户的共情传播机制研究 ——基于情感共情和认知共情双过程探索

互联网"圈子"的形成,加速了危机事件传播的速度与效率,使得信息流动更加快速、便利.但危机事件的全面渗透造成了公众心理和情绪的快速形成、更替与变迁,人们开始正视危机事件中关于"理性"与"感性"的辩证思考.基于此,研究通过危机事件、共情传播以及传播效应的相互关联分析,提出了规律性假设,并应用实证分析进行了具体事例的认知探索.结果表明,危机事件中互联网"圈子"用户的共情传播机制呈情感共情和认知共情双过程表现,且各假设成立.同时,研究又根据实证中提取的要素特征和传播路径,构建了共情传播要素评价体系,勾勒了危机事件中互联网"圈子"用户的共情传播演化机制与发展轨迹,讨论了共情传播路径探索新思路.
