In this paper, a quasi - one - dimensional Lagrangian analysis method is presaent-ed. This method with the profiles of the pressure and the radial displacement at different Lagrangian positions, which determined from the two -dimensional (2-D) Lagrangian experimental technique for the input, can be used to solve the flow field near the axis of a 2- D shock initiation process. As a preliminary application, we show the analysing results of 2- D shock initiation process in pressed TNT at two loading conditions.
