2、Background Pt，Hg，Hg2Cl2(s) | Cl-(c) E = = 0.2415 VParameters Setting vElectrochemical Workstation（CHI600B）The Taguchi method IntroductionvAdvantage of The Taguchi method 1、Reducing the variation in a process 2、Produce high quality product at low cost to the manufacturer 3、How different parameters af
3、fect the mean and variance of a process 4、Performance characteristic defines how well the process is functioning orthogonal Experimental Designv The collection of the necessary data determine factors most affect product quality with a minimum amount of experimentation, thus saving time and resources
4、. v The Taguchi method is best used when there is an inter- mediate number of variables (3 to 50), few interactions between variables, and when only a few variables contribute significantly.
