Abstract：

It　is　important　to　analyze　the　propagation　characteristics　of　guided　waves　in　acoustic　leak　location　in　pipelines.　In　this　paper,　the　acoustic　leak　signal　is　analyzed　in　the　time-frequency　domain.　Based　on　the　relation　of　time-frequency　distribution　of　the　acoustic　leak　signal　and　the　dispersion　curves　of　guided　waves,　the　mode　components　of　acoustic　leak　signals　were　obtained.　The　research　can　provide　a　guideline　for　the　mode　selection　in　pipeline　leak　location,　and　help　improve　the　accuracy　of　leak　location.　©　Higher　Education　Press　and　Springer-Verlag　2006.
