突变点检测方法的应用——基于电导渗滤模型的微乳液类型的区分

摘要

Introduced the mutations point detecting methods into the distinguish of microemulsion structure, basing on the conductivity filtration model. Which combined with software programming to produce little program module which could find the mutations point of conductivity quickly and accurately. It thus could alternative the traditional method which found the mutations point of the conductivity curve by visual read to confirm the W/O area of microemulsion system. Contrasting four commonly used mutations point detecting methods：slide t method, Cramer method, Yamamoto method and Mann- Kendall method. Which proved that the slide t method was the best mathematical model to confirm the W/O area of microemulsion system.%在电导渗滤模型的基础上，通过引入检测突变点的数学方法，结合软件编程制作小的程序模块，以快速准确地找到电导率的突变点，从而替代传统的目测读取电导率曲线突变点的方法来确定微乳液体系的W／O区域。对比了四种常用的检测突变点的数学方法：滑动t法、Cramer法、Yamamoto法和Mann—Kendall法，证明采用滑动t法作为数学模型来确定微乳液体系的W／O区域效果是最好的。
