三米跳板跳水空中技术动作的三维运动学分析方法

旨在建立适合三米跳板跳水空中动作的三维运动学分析方法。方法:用安装于笔记本电脑的运动采集软件及其相连接的两台DV摄像机同步采集三米跳板跳水空中动作。用三维标定框架置于跳板上进行标定拍摄。用SIMIomotion运动录像分析系统解析空中动作。用前述方法考察杆状物体在3×2×7m空间范围运动时所解析获得长度的误差。结果:解析获得运动员头部、颈、腕关节、肘关节、肩关节、躯干中心点、髋关节、膝关节、踝关节、跳板等关键点的三维位移和速度。同时获得运动员质心的位移和速度,腾空时间,起跳角度等关键技术指标。误差分析表明,本方法最大误差小于3%。结论:本研究建立了三米跳板跳水三维运动学分析的有效方法。

数学分析教学中的若干意见

时高师数学分析的教学进行了探讨和研究，有针对性的提出了数学分析教学中应贯彻的六个“注重”：即注重引导学生主动建构数学分析知识结构；注重“良好的开始等于成功的一半”，讲好ε-语言；注重数学活动过程的教学；注重教学思想方法的教学，贯彻理论性与应用性相结合的原则；注重体系的内在统一，打破理论本身的封闭性和知识结构的单一性；注重发挥习题课的作用，上好习题课。     

What contemporary work are student ratings actually doing in higher education?

It is conventionally assumed that student ratings perform a significant function in driving improvement in pedagogical practices in higher education. As a result, this form of evaluation has gradually become institutionalised in recent decades as an essential proxy for understanding teaching and course quality in universities across the world. However, with the rise of market-based models in higher education and heightened expectations for accountability mechanisms, the role and functional purpose of ratings-based student evaluation have become increasingly confused. This rising ambiguity has created strong tensions between the seminal drive of student ratings as a tool of quality improvement, and the emerging demands for its use as a transparent accountability measure for the comparative assessment of academic performativity. So are student ratings now largely a tool of quality assurance or performance measurement, or do they remain a legitimate tool for pedagogical improvement? This paper reports on a study that responded to this critical question by considering the contemporary work of student ratings in a major Australian university. The outcomes of this research demonstrate that tension between improvement and accountability motives is causing considerable confusion and discord around the role and value of the student voice. It also reveals that academics are tending to discount the often critical insights of students on the implications of their pedagogical practices as a result of the elevating institutional role of student ratings as a proxy for teaching quality. In considering these outcomes, rising levels of academic dissonance around student ratings would suggest a necessity to consider broadened evaluative strategies that are able to more effectively capture the improvement potential offered by the student voice.     

中药注射剂荧光光谱三维聚类图分析研究

测定了5种56个批次的中药注射剂的二维荧光光谱,提出了激发光谱的第二特征峰的概念,首次以激发波长、发射波长和激发光谱的第二特征峰波长作为基,建立了三维聚类图分析法。结果表明：激发光谱的第二特征峰波长具有较好的特征性;三维聚类图有较好的分类和预测作用,并有较强的可视性。该法可用于中药注射剂的鉴别和聚类分析。     

济南市公共交通低碳发展路径探索

交通在为城市发展做出巨大贡献的同时,其占能源消费和碳排放比重不断攀升,使城市发展面临排放增加、环境污染等诸多问题。根据济南市交通工具现状、技术水平等变量建立LEAP模型,测算实施CNG\LNG清洁能源计划的减排潜力。结果表明:实施CNG\LNG计划到2030年可减少约1200万吨CO2排放,约占未实施CNG\LNG计划交通行业排放的45%,减碳作用明显。
