摘　　要：本文采用基于时间序列与动态数据处理的门限回归方法改进现有的单一线的定线方法,通过实例研究表明,新方法较现有的方法精度更高、稳定性更好。Threshold regression is a method in time series and dynamic data processing, based on thresholds variables and threshold values. Threshold regression was used to improve existing single curve method. The case studies show that the new method has higher accuracy and better stability than the existing method.
