| 摘 要： | 结合因子分析的特点,对调研数据进行标准化处理,样本检验结果显示适合因子分析.通过数据分析及陡坡图上的坡度显示,确定出4个特征值大于1的公共因子,来作为因子分析的命名指标.对初始的矩阵进行转置,使公因子对各指标的贡献两极分化,确定公因子的命名解释,从而得出限速的优化模型.

| Abstract: | The survey data were standardized integrating with the characteristics of factor analysis.The results of sample test proved that the sample is suitable for factor analysis.According to data analysis and the slope degree showed on steep slope graph,four common factors whose characteristic values were greater than 1 were determined as denomination indexes of factor analysis.Transposing the initial matrix to polarize the contribution of common factors to each index,the explanation of denomination of common fac... |
