英语翻译为了选出最有用的几个评价指标,我们建立了多元统计筛选模型对8个指标进行因子分析,提取出了评价指标的三个主成分：经

For selecting several evaluation index signs, we built up diverse covariance sieving model to carry on factorization to 8 index signs, withdrawing to evaluate index sign of three main compositions:The economy throws in factor, special disease prevention and cure factor, female baby health factor, show the 著 ground to this 8 index signs and is divided into 3 types.After we lead to build up 3D factor to get a goal matrix into time factor according to that model, the covariance been worth by 3 main compositions distributes of the variety distinguish global health system history a change of the process and the trend.
