英语翻译The Taguchi method is an experimental design technique[14,15],which provides a simple way to design an efficientand cost effective experiment.In order to efficiently reducethe numbers of conventional experimental tasks,the orthogonalarray [16,17] by using design parameters (controlfactors) in column and standard quantities (levels) in row isproposed and further adopted.The performance measuresignal-to-noise ratio (S/N) [18] proposed by Taguchi is usedto obtain the optimal parameter combinations.The main attribute of the Taguchi method is to quantifythe S/N (signal-to-noise) ratio as the quality index.Thelarger S/N means the relation to quality will improve.Thelower quality characteristic will be regarded as a betterresult when consideringsmaller-the-best quality.The relatedS/N ratio is defined as（某公式1）where n is the number of experiments for each experimental set,and yi expresses the quality characteristic at the i-thexperiment.In contrast,the larger quality characteristic willyield a better result when considering the larger-the-bestquality; therefore,by taking the inverse of quality characteristicinto Eq.(1),the related S/N ratio can also bededuced and shown in Eq.(2).（公式2）
