stagewise

1.Preceding them with an omnibus F test in a stagewise testing procedure defeats this design, making it unnecessarily conservative .

在此之前使用F检验会破坏这种设计，得到一个相当保守的结果，这是的。

2.Finally,the most reasonable technological process of“stagewise grinding,coarse and fine classification,gravity separation magnetic separation reverse anionic flotation”has been found out.

最终推荐“阶段磨、粗分级、重-磁-阴离子反浮”合理工艺流程。
