求翻译：3. 利用主成分分析法，对统计过的数据进行整合处理，将限速时考虑的多因素变量进行降维处理，得到对道路限速时的主要参考因素。是什么意思？

Using principal component analysis, statistics on data integration processing, multi-factor variables considered in the speed limit to reduce the dimension of speed limit on the road of the main reference.

3.- The ingredients of the statistical methods of analysis, the data integration process, and will be taken into account when speed-limit the number of factors in the process variables are on the road, speed limits, the main reference.

3. Using the principal components analytic method, to has counted the data carries on conformity processing, regulating when considered the multi-factor variable carries on falls Uygur to process, obtains to time the path regulating main reference factor.

3. using principal component analysis, to consolidate statistical data that have been processed, will consider multiple factors when the speed limit reduced-dimension a variable, get on Highway speed limits of major factors.
