摘要
目的:通过对文献关键词进行分析,阐释了我国机能实验学的研究现状。方法:对"中国知网"收录的与机能实验学有关的1 519篇论文进行了关键词提取,以发表年份为因变量,以词频≥4次的234个关键词为自变量,采用逐步纳入法进行了多元线性回归分析。结果:共提取到25个有效关键词,回归模型F=10.520,P=0.000,线性拟合良好。结论:数据分析的结果与业界对本学科的认知基本一致,从数据上印证了本学科的特点和发展方向。
Objective： To explain the current status of our country’s research of functional experiment through the analysis of the literature keywords. Methods： To extract the keywords of the 1 519 journal papers related with functional experiment and collected in CNKI,and taking the publishing year as the dependent variable and 234 keywords with the word frequency with the word frequency that is equal to or greater than four as the independent variables,to conduct the multiple linear regression analysis by using the stepwise accepting method. Results： A total of 25 effective keywords were extracted,and the regression model was F =10.520,P =0.000,and the linear fitting was good. Conclusion： The results of data analysis are consistent with the industry’s cognition of the subject, which confirms the characteristics and development direction of the subject from the data.
