中文摘要：

文章根据生命周期理论和文献增长律对学术传播发展阶段进行了界定与区分,并借用传播要素理论定义了基于科学文献的学术传播中的各个传播要素。在此基础上,以中国学术期刊网络出版总库（CNKI）为数据来源,以“新能源”领域1977—2012年间发表的科技期刊论文为例,研究了在学术传播的不同阶段中文献传播各个要素演变的状态与呈现的规律,探索了传播要素之间相互作用的机制。并根据各个传播要素整体增长状态统计分析和传播要素相互关联数据,初步构建了学术传播阶段中文献传播要素间的函数关系模型。

英文摘要：

This paper defines and distinguishes the development stages of scholarly communication according to the lifecycle theory and literature growth law. Then, the paper defines each communication factor of scholarly communication based on scientific literature through the theory of communication factors. On the basis of this, the paper takes CNKI as the data source and scientific papers of ＂new energy＂ published from 1977 to 2012 as samples to research the evolution status and law of each communication fac- tor in the different stages of scholarly communication, as well as explore the interaction mechanism of communication factors. Finally, according to the statistical analysis of the overall growth state and the interaction data of communication factors, the paper constructs the functional relationship model of literature communication factors in the stage of scholarly communication.
