摘　　要：探讨1990-2010年中国在医学领域8个学科SCI/SSCI收录期刊发表论文的作者合作度分布规律和不同合作模式与论文影响力的关系。结果表明,目前医学领域几乎不存在单作者论文,免疫学和分子生物学与遗传学等基础学科的合作度较高,各学科论文的作者合作度近似符合Zipf(齐普夫)定律,且分布具有不均匀性,多作者、国际、机构间合作论文的被引次数分别显著高于单作者、国内和机构内合作(p<0.01)。国内合作论文中,机构内合作和机构间合作的论文被引次数没有显著差异,作者数、机构数和国家数的增多均会导致论文影响力的升高,多作者、多机构和国际合作对论文影响力的促进作用逐渐增强。研究作者数与论文影响力的关系,应考虑不同学科的合作水平。The relation between the distribution rules and model of power of papers in 8 medical subjects published in journals covered which showed that papers published by a single author were practically such as immunology, molecular biology and genetics was rather high, cooperation of Chinese authors and influence in SCI/SSCI from 1990 to 2010 was studied, nil, the cooperation of authors in basic sciences the cooperation of authors in different subjects accorded with the Zip law and was characterized by unevenness, the number of citations of papers cooperated between several authors and international institutions was significantly higher than that of single author and domestic institutions （P〈0.01）. No significant difference was found in citations of papers cooperated between domestic intra - and inter-institutions. The increased number of authors, institutions and nations would lead to higher influence power of papers, and cooperation between multiple authors and international institutions would increase the influence power of papers, the cooperation level in different subjects should thus be taken into consideration when the relation between the number of authors and the influence power of papers is studied.
