成万祥  张庆文 《上海体育学院学报》2006,30(6):45-50

采用高速摄像、录像解析及比较分析方法,对我国优秀标枪运动员陈奇投掷步相关运动学参数进行比较分析。结果发现陈奇投掷步的技术特点:助跑距离较长、助跑速度较快,第二交叉步前后速度损失同投掷成绩呈负相关;第一交叉步前后身体重心速度的增加幅度同交叉步前后躯干后倾角变化量呈负相关,第二交叉步前后身体重心速度的损失幅度同交叉步前后躯干后倾角变化量呈负相关;最后一步前后身体重心水平速度的损失幅度同躯干后倾角变化量呈正相关。  相似文献

Seeking Nettle Textiles – Utilizing a Combination of Microscopic Methods for Fibre Identification     

Jenni A. Suomela  Krista Vajanto  Riikka Räisänen 《文物保护研究》2018,63(7):412-422

Bast fibres have been commonly used as a textile material in Northern Europe since Neolithic times. However, the process of identifying the different species has been problematic, and many important questions related to their cultural history are still unanswered. For example, a modified Herzog test and the presence of calcium oxalate crystals have both been used in identification. In order to generate more reliable results, further research and advancement in multi-methodological methods is required. This paper introduces a combination of methods which can be used to identify and distinguish flax (Linum usitatissimum), hemp (Cannabis sativa), and stinging nettle (Urtica dioica). The research material consisted of reference fibres and 25 fibre samples obtained from 12 textiles assumed to be made of nettle. The textiles were from the Finno-Ugric and Historical Collections of The National Museum of Finland. The fibre samples were studied by observing the surface characteristics and cross sections with transmitted light microscopy, and by using a modified Herzog test with polarized light, in order to identify the distinguishable features in their morphological structures. The study showed that five out of 25 samples were cotton, 16 nettle, one flax, and one hemp. Findings from two samples were inconsistent. The results show that it is possible to distinguish common north European bast fibres from each other by using a combination of microscopic methods. Furthermore, by utilizing these combined methods, new and more reliable information could be obtained from historical ethnographic textiles, which creates new vistas for the interpretation of their cultural history.  相似文献   

Reimaging Public Libraries as Learning Communities: What Library Stories Can Tell Us     

Deborah Eicher-Catt  Mina Edmondson 《Public Library Quarterly》2016,35(3):203-221

This article describes a study conducted in York County, Pennsylvania, on its countywide library system framed within the context of the statewide “Reimaging Libraries” Get Storied initiative, developed and marketed by organizational story consultant, Michael Margolis. Understood as an essential aspect of culture re-imaging and change, narratives were collected from library personnel by undergraduate students at Pennsylvania State University-York as part of a service-learning initiative (directed by the first author). Working closely with the library district consultant (second author), we assess the success of the initiative and make some recommendations for culture reimaging through the practice of storytelling.  相似文献

文化传递与直译     

黄碧蓉 《邵阳学院学报(社会科学版)》2004,3(5):96-97,100

翻译离不开文化的传递，翻译的主要任务是在的文(target text)中再现原文(source text)的思想内容，促进文化交流。文章从分析东西方文化意义完全不同的两组对应词“龙”和“dragon”与“东风”和“west wind”入手，阐明了翻译中的直译是值得推崇的文化传递途径，其能保留原语文化，使读者感到新鲜生动；能丰富译语文化，扩大读者的知识视野：能促进文化交流，丰富和提高民族文化。  相似文献   

化学教学中的几个疑难问题浅析

硝酸的强氧化性从其分子结构中分析,+5价氮不稳定;氯酸钾热分解中有O2、ClO2、Cl2、O3、HCl,存在着一些副反应;锌跟浓硫酸作用产物多样化,原因是产物中物质会继续发生氧化还原反应;硫酸钡沉淀能适当地溶于浓硫酸,其主要原因是形成了酸式盐。  相似文献

跨文化的有效沟通——以（广东）省港澳地区为例     

孙东川  陈伟翔 《河南师范大学学报(哲学社会科学版)》2003,30(3):121-123

随着世界各地越来越多的企业组织跨越地域界限，甚至跨出国门来拓宽自己的生存空间，合资企业与合作经营的浪潮已势不可挡。合资与合作的深层含义就是相异的文化在碰撞中寻求融合和协同。跨文化管理所涉及的课题甚多，本文只集中讨论跨文化的沟通。为此，本文访问调查了一些香港和澳门在中国内地的管理决策人员和投资者及中国内地驻香港或澳门中资企业的管理决策人员，希望首先借用同文同种、但由于历史原因形成不同文化背景的(广东)省港澳地区的跨文化沟通经验来论述跨文化的有效沟通。  相似文献
