Although the governing equations of flow are well known,we find no analytical expressions that exactly describe the complexity of turbulent motion,due to the complexity with the turbulence. But recenty periodic solutions in the spatially localized turbulence are discovered by Avilla et al.(2013). In this study,edge-tracking,a kind of bisection,is conducted in order to find the boundary of turbulent flow and laminar flow. We exhibit the features of spatially localized structures in the boundary,and their differences from those in a well-known turbulent puff.
