公共图书馆如何吸引读者参与读者活动

近年来,政府加大了对公共图书馆事业的投入力度,公共图书馆不再仅限于传统的图书借还功能,组织举办读者活动已成为图书馆的重点工作. 分析了公共图书馆举办的读者活动引不起读者兴趣的原因,提出了解决这一问题的对策和建议.     

创新开展新时期科技名词规范化工作,努力发挥支撑服务作用

科技名词规范化工作具有深厚的历史基础和现实需要,是支撑科技创新和经济社会发展的一项基础性系统工程。当前,中国特色社会主义进入新时代,我们要深刻领会“新时代”的丰富内涵,深化认识科技名词规范化工作的特殊意义,创新开展各项工作,更好肩负起新时代赋予的历史使命。     

基于APAS的篮球技术链攻防时空特征研究

运用三维影像解析系统软件对持球顺步突破后跨步急停跳投这一技术链的攻守影像进行解析.研究结果表明,篮球技术链中每一项技术的运用都有其时间和空间适用性,如果运用得当,链内技术可以产生互为运用手段、互相创造时空条件的效果;经测试,高水平篮球运动员脚的简单反应时和动作反应时高度相关,但在持球队员运用该技术链向左侧突破时,技术链前端技术不能为末端的投篮技术创造时空优势.     

"医疗器械"一词的英译与思考

近年来,随着国内医疗器械领域的创业公司不断兴起,“医疗器械”一词被广泛使用于公司名称注册、内容介绍、网站宣传及产品使用说明等方面,而其英译名却五花八门,没有统一的标准。文章通过数据采集、实例分析来辨明“医疗器械”各种英译的区别,旨在为广大译者提供有关该词的英译思路。

Developmental modes of the Neoproterozoic-Lower Paleozoic marine hydrocarbon source rocks in China

Based on the researches on rock type, the mode of occurrence, diagnostic minerals and creatures, the sedimentary geochemistry and organic facies of Chinese marine source rocks from wells and outcrops, and on the research findings of developmental modes of foreign marine source rock, the authors consider that it is impossible to objectively make clear the formation mechanism of hydrocarbon source rock with high organic matter abundance by either single mode of preservation or high organic matter productivity. According to the Chinese geological features, the formation mechanism of the Neoproterozoic-Lower Paleozoic marine source rock is generalized into four modes, namely, thermal water activity-upwelling flow-anoxic; carbonate gentle slope-upwelling flow; xerothermic climate-brine euxinic milieu; and humid climate-retained euxinic milieu; as the Lower Cambrian undercompensation basin organic facies （the Tarim Basin, South China and southwestern margin of North China）, carbonate gentle lime mud bound organic facies （the Upper Ordovician in Tazhong region of the Tarim Basin and the Lower Silurian in the Upper Yangtze Platform）, the Middle Cambrian evaporation laggon organic facies （the Tarim Basin and the Upper Yangtze Platform）, enclosed undercompensation terrigenous bay organic facies （the Middle-Upper Ordovician in the west of the Tarim Basin, the Lower Silurian Long- maxi Formation in the Upper Yangtze platform）. Chinese marine sedimentations with lower organic matter abundance are generalized into two modes of consumption-dilution mode of open epicontinental sea and depletion-dilution mode of supercompensation basin.     

A NEW DESCRIPA NEW DESCRIPTOR OF AMINO ACIDS BASED ON THE THREEDIMENSIONAL VECTOR OF ATOMIC INTERACTION FIELD

QUANTITATIVE STRUCTURE ACTIVITY RELATIONSHIP (QSAR) IS A VERY IMPORTANT TOPIC FOR MANY SCIENTIFIC FIELDS AND CAN BE TERMED AS QUANTITATIVE SEQUENCE ACTIVITY MODELS(QSAM)[1] WHEN REFERRED TO THE RESEARCH ON RELATION- SHIPS BETWEEN STRUCTURES AND ACTIVITIES OF BIOLOGICAL MOLECULES, SUCH AS PROTEINS, AND NUCLEIC ACIDS. HOW- EVER, IT IS VERY DIFFICULT TO ESTABLISH A QSAM MODEL,…
