一个国家在国际科学期刊上发表的论文数量（通常根据SCI即《科学引文索引》来统计）及这些论文的被引用次数，是反映一个国家科研水平的重要指标。

A country in the international science journal publications(Usually based on SCI namely[Science citation index]To statistics)And these papers cited frequency,Reflects a national scientific research level of important index.

　　1987年，当中国科学技术信息研究所开始中国科技论文统计分析工作的时候，SCI收录的中国科技人员发表论文数量在世界上的排位大致是二十七八位。到了2010年，中国的SCI论文数已经排在世界第二位。但是，中国论文数还不到美国论文数的一半，对此我们也要有清醒的认识。

In 1987,,When China science and technology information institute began to Chinese scientific and technical papers statistical analysis work,SCI collection of Chinese scientific and technical personnel number of published papers in the world ErShiQiBaWei qualifying is roughly.By 2010,Chinese SCI papers have been ranked second in the world.but,Chinese paper number less than half the number of papers,So we also should have clear understanding.

　　一个国家发表论文的被引用总数，反映着该国科学研究的质量或影响。2011年，我国科技人员发表论文的被引用次数排在世界第七位，比2010年时提前了一位。2010年与2006年相比，中国SCI论文数年均增长19%，而被引用次数年均增长30%。我们估计，中国论文的被引用次数将于2014年进入世界前5位，提前实现《国家“十二五”科学和技术发展规划》规定的目标。

A country of the total number of papers cited,Reflecting the country's scientific research quality or influence.In 2011,,Our country science and technology personnel published papers cited frequency row seventh in the world,More than 2010 advance a.In 2010 compared with 2006,Chinese SCI papers grew at an average annual rate of 19%,And cited times the average annual growth of 30%.We estimate that,Chinese papers cited times in 2014 will be to get into the world's top five,Early realization[countries"1025"Science and technology development planning]Stated goal of.

　　不难看出，过去10年来不仅我国的论文数量大幅上升，论文质量也随之水涨船高。这是我国重视科技创新、加大科技投入、科研人员辛勤工作的必然结果。

It is easy to see,In the past 10 years in China not only the number of papers to rise sharply,The paper quality has a rising tide lifts all boats.This is our country pay attention to scientific and technological innovation/Increase science and technology investment/Scientific research personnel the inevitable result of hard work.

　　当然，我们也要看到，与发达国家相比，中国平均每篇论文的被引用次数（简称“篇均被引次数”）还比较低，目前的篇均被引次数低于世界平均值。

Of course,We also want to see,Compared with the developed countries,China's average each paper of the cited frequency(Referred to as"Article were lead times")Is relatively low,The present article were lead times lower than the world average.

　　原因主要有两点。第一，是非英语国家的论文不太容易获得英美科研人员的引用。同属非英语国家的科技大国日本，其篇均被引次数迄今也低于世界平均水平，但比中国更接近世界平均水平。第二，是中国发表的所有论文中，有35%以上是零被引论文（从未被引用过1次）；英国的零被引论文不到25%。由于零被引论文所占比例较大，就把总体的篇均被引次数拉下来了。但是，仔细观察被引用次数的分布曲线可以看出，中国的高被引论文数其实并不少。

There are two main reasons.The first,Is English national papers not too easy for British and American researchers reference.Belong to the English national science and technology power Japan,The article were lead times so far also lower than the world average level,But more than China close to the average level in the world.The second,Is China published in all of the papers,More than 35% is zero cited papers(Never been cited one);Britain's zero cited papers less than 25%.Because zero cited papers which have a large proportion,The general papers which cited frequency down.but,Observe carefully cited number of distribution curve can be seen,China's highly cited papers in fact and many.

　　论文从发表到被引用有一定的时滞，引用高峰一般出现在发表2至5年后，具体时间因学科不同而有差异。中国已经发表了数量可观的论文，几乎可以肯定的是，再过几年，中国将有更多的论文获得引用，高被引论文的数量也会进一步增加。

This paper cited published to have certain delay,Reference peak generally appear in the published 2 to 5 years,The specific time for discipline will vary.China has made significant quantities of thesis,Almost certainly,In a few years,China will have more paper for reference,The number of highly cited papers will further increase.
