中文摘要：

鉴于在试验设计中估计交互作用的繁杂性,提出一种快速简捷估计两因素交互作用的新方法。该方法应用过程简单、计算量小,具有很好的稳定性、可靠性及精确性。同时也分析了该方法适用于实际应用的特征,并用非线性二次回归模型说明原理。

英文摘要：

Because of the complexity of estimating the interaction by experiment design,this paper proposes a new method to estimate the interaction quickly and easily.This method is simple in application and requires small calculation work.It is stable,reliable and precise.Also this paper analyzes the fea-tures suitable for the actual application of this method,and explains the underlying mechanism with non-linear quadratic regression.
