摘　　要：通过逐步回归分析，建立起稀土钙钡和７５ＳｉＦｅ孕育剂指标与其影响因素之间相关关系的回归方程。并以此为基础，系统比较研究了稀土钙钡和７５ＳｉＦｅ孕育剂在不同工艺条件下的孕育效果。The regression equation, a relative relationship between the inoculative effects and the influentialhctors for RE-Ca-Ba and 75SiFe, has been established through stepwise regression analysis, On the basis of theregression equation, the inoculative effects for RE-Ca-Ba and 75SiFe in different technological conditions havebeen studied contrastly and systematically.

关 键 词：逐步回归分析 稀土钙钡 比较 孕育 孕育剂
