七运会女子10公里竞走冠军李春秀技术解析     

李淑芳 《山东体育学院学报》1994,(1)

李春秀在第２５届奥运会夺得女子１０公里竞走铜牌，在第七届全运会夺得金牌，创造了亚洲记录，逼近世界纪录。采用高速摄影和影片解析的方法，对其在六运会比赛中的竞走技术进行定量参数解析。结果显示，其步频、步长、腾空时间、单步水平速度、身体重心起伏、支撑腿技术、躯干与水平面夹角等与世界优秀选手陈跃玲、萨克斯比接近或一致，说明其技术是合理的。  相似文献   

女子三级跳远三跳起跳技术的生物力学评价   总被引：10，自引：0，他引：10  

李建设  胡宗元  贺辉 《体育科学》1992,(2)

本文建立了一个适合于评价三级跳远技术水平的系统评价框图,并根据这个框图设计了一个决定三级跳远效果的生物力学参数系统。利用这个系统分析和评价了当代女子三级跳远亚洲纪录保持者李惠荣的三级跳远技术(所用技术影片是在1989年全国田径冠军赛上用LOCAM型高速摄影机以每秒100幅的速度扫描拍摄的),并通过与男子三级跳远运动员的技术特征的比较,找出了其技术上的优势和不足,并就如何改进和完善其三跳技术提出了一份系统而直观的研究报告。同时为女子三级跳远的再研究提供了可供借鉴的研究方法。  相似文献   

人体下肢肌肉功能模型及其应用的研究     

单大卯 《体育科研》2003,24(4):16-20

研究人体在运动过程中,肌肉长度、肌长度变化速率、肌力臂等肌肉功能参数以及肌肉功能的动态变化,是运动生物力学、运动解剖学、运动生理学和体育训练学等学科领域中十分关注的课题,它们对于深入探讨人体运动规律、肌肉的神经控制与工作特性以及制定肌肉专项力量训练方案等均具有非常重要的理论和实践意义.为此,本文将以人体下肢肌肉附着点(肌肉起止点、代起止点)、关节转动中心在相应环节基准坐标系中的坐标为基础,建立适合于活体应用的下肢肌肉功能模型.该模型不但能详尽地定量评定下肢于不同状态下肌肉所具有的潜在功能,而且也能获得人体在运动过程中下肢肌肉功能参数的动态变化状况.同时,本研究通过步态分析的实例,初步检验了模型的可用性和可靠性.  相似文献   

Investigation of the Painting Idyll Attributed to Henryk Siemiradzki: The Unusual Technology of a Canvas Painting Executed on an Enlarged Photograph     

Dominika Sarkowicz  Anna Klisińska-Kopacz 《文物保护研究》2018,63(5):251-266

The subject of the research is an oil painting entitled Idyll created using an unusual technique. The painting layer was applied on canvas covered with photosensitive medium on which a photograph was developed. The results of the examination of Idyll in the context of its attribution to Henryk Siemiradzki (1843–1902) are discussed. Its atypical technology and the possibility of the artist having used the photographic technique are also considered. X-ray fluorescence spectroscopy, infrared spectroscopy, and scanning electron microscopy were performed to establish the technique and to characterize the pigments and materials used in the painting. The identified pigments and the information provided by analytical photography (UV, X-ray images) were compared with the results of the detailed examination of 56 of Siemiradzki’s oil paintings. Performed analyses revealed that the majority of the features identified in Idyll point to Henryk Siemiradski’s technique.  相似文献   

The Visual Holdings of the Slavonic Library,Prague     

Lukáš Babka 《Slavic & East European Information Resources》2017,18(3-4):165-184

This study focuses on the visual collections in the holdings of the Slavonic Library (a section of the National Library of the Czech Republic). The library holdings also include unique collections relevant to the topic of Russian and Ukrainian emigration: collections of visual art, ex libris, posters and flyers by Ukrainian émigrés (1918–1945), and a collection of invitations and flyers by Russian émigrés (1918–1945). Rudolf H?lka’s collection of photographs, dating back to the 1920s, captures a series of ethnographic, folkloric, and architectonic phenomena which no longer exist. Moreover, Russian posters from the period of WWI, from the revolutionary year of 1917, and the subsequent civil war are equally fascinating as are banknotes from the same period and region.  相似文献   

Self[ie] reflective practice: revealing student engagement through the photographic performance of the self     

Helen Jackson 《Learning, Media and Technology》2019,44(2):144-161

ABSTRACT

This paper positions the photographic image of the self (the ‘selfie’) as the reflexive indicator on which students are prompted to reveal their learning behaviours, and uses this mode of reflexivity to construct a qualitative study of engagement in a higher education setting. The study leverages the intensified processes of self –reflection created by the novel forms of convergence across the social landscape in which the selfie is embedded, to reveal how oppositional and indexical selfie-reflective practices can operate to uniquely connect behaviours to learning in this sector.  相似文献

A turn to realism and humanism from propaganda: Chinese photojournalism practices between 1976 and 1988     

Shi Li 《亚洲交流杂志》2018,28(2):115-134

China’s photojournalistic field undertook great transformations in the 1980s. While the conservatives continued to cling to the propagandistic doctrine, a more progressive trend was emerging. The tension between these two forces had deep historical roots and went on to shape the way Chinese media photography developed. Based on archival research and in-depth interviews, this article revisits the history of Chinese media photography practices between 1937 and 1988 and identifies the key features of three distinct periods: wartime propaganda between 1937–1949; the intensification of ideological propaganda between 1949–1976; and the transformation to realism and humanism between 1976–1988.  相似文献   

论陈复礼摄影创作的璀璨艺境
