ABSTRACT
Modern experimental and computational fluid mechanics are in-
creasingly concerned with the structure nature of fluid motion. Re-
cent research has highlighted the analysis of one transport structure
which is called Lagrangian coherent structure. However, the quan-
tity nature of the flow transport is still unclear. In this paper, we
focus on the transport characteristics of physical quantities and pro-
pose an approach to visualize the finite-time transport structure of
quantity advection. This is similar to an integral convolution over
