Abstract: In order to resolve the problems that the analysis results of mu-level algorithm were influenced easily by measurement and detection parameters,the adaptability of burst-detection in turbulent boundary layer were researched in detail.Through contrast analysis of vertical testing position,sampling frequency,sampling time,boundary-parameter and accessional determinant condition,the influence rules of above factor on burst-detection were acquired,and feasible approaches to enhance burst frequency veracity in turbulent boundary layer were discussed.Finally,a four-step method of detecting burst frequency with mu-level algorithm(fore-sampling,fore-analysis,sampling,detection analysis) was summarized.
