The citation amount,type of citation,citation languages,citation years,the Price index,citation half-life and rate of self-citation had been calculated.
为了解我国体育类期刊的引文质量,采用引文计量分析法对11种体育类期刊(5种核心期刊、6种普通期刊)2006年刊载的2613篇论文的22286条引文进行统计分析,从引文数、引文类型、引文文种、引文年代分布、普赖斯指数、引用半衰期和自引互引情况等方面比较分析其引文特点。
According to bibliometrics,citations have been calculated for Journal of Xiangtan Mining Institute from 1994 to 1998,the citations per paper are lower than the whole country,the self citations rate and self citations per paper are equal to same journals of the country,the coorperation degree of the writers is middle at home and abroad.
用文献计量学和统计学方法计算出 5年 2 90篇论文的平均引文量为 4 2 ,低于全国平均值 ,而引文篇率接近于全国高值 ,自引率和自引篇率与国内同类刊物相当。
It analyses the regulation of Journal of Zhejiang Normal University on the total of the yearly published theses,subjects distribution,citation numbers,type of references,languages and self citation.
本文运用文献计量学中的统计分析方法,对1990~1998年《浙江师大学报》(自然科学版)所发表论文的数量、学科及引文进行统计,分析了《浙江师大学报》的载文量、载文学科分布、引文数量、类型、文种、自引分布上的规律,从一个侧面反映了浙江师范大学的科研现状和《浙江师大学报》的学术质
A novel self-photoinitiating pure acrylate was synthesized.
合成了一种全新的自引发纯丙烯酸酯,利用实时红外光谱技术研究了自引发感光高分子的光聚合过程,比较了不同引发剂浓度下的聚合速率和转化率;结果表明,引入到高分子侧链的自由基引发剂仍具有较高的引发活性,双键基团也具有很好的光聚合反应活性。
Novel self-photoinitiating polyacrylate acrylate has been synthesized, the photopolymerization kinetics of the novel self-photoinitiating polymer was investigated by real-time FTIR spectroscopy.
合成了一种自引发纯丙烯酸酯,利用实时傅立叶红外光谱(RT-FTIR)技术,研究了紫外光照下的自引发感光高分子的光聚合过程,比较了不同引发剂浓度下的聚合速率和转化率,结果表明引入到高分子侧链的自由基引发剂仍具有较高的引发活性,双键基团也具有很好的光聚合反应活性。
In this thesis, novel self-photoinitiating polymer has been synthesized with introduction of radical initia.
为此,我们合成了一种聚丙烯酸脂,并通过一系列有机合成,在高分子侧链成功引入了自由基引发剂2-羟基-甲基苯基丙烷-1-酮(1173)和光聚合活性单体丙烯酸-2-羟乙酯(HEA)结构,得到一种全新的具有自引发功能的感光高分子,这种材料在进行光聚合后,没有光引发剂的碎片和小分子单体的残留,将大大降低其生物危害性。
