摘要 基于66种力学期刊论文的参考文献,利用引文分析法对力学期刊的引文进行统计和分析,得到力学期刊群的引文矩阵。通过余弦函数将引文矩阵转化为相似矩阵,并运用多维尺度分析法将力学期刊之间在引文上的相似性转化为平面距离,以平面图直观地展现出力学不同分支学科期刊子群在引文上的关系。在通过因子分析将66种力学期刊复杂的内部关系转换为少数几个不相关的因子的同时,考察了力学期刊群的构成和内部关系,从而探索了力学学科的结构。 Based on the references of papers from 66 mechanical journals,through citation analysis,the paper gets the journal citation matrix.Through the cosine function,journal citation matrix is changed to similarity matrix.Then using multidimensional scaling analysis,the paper reflects their similarity in the citation by use of the horizontal distance,and it is shown citation relations of the different mechanical sub-branch journals by a visual map.At last,using factor analysis,it converts complex internal citation relations of 66 mechanical journals to a small number of independent factors.The paper reveals the mechanical journals composing and the interior relations among the several mechanical sub-branch journals,it explores the mechanical disciplinary structure.
