| Abstract: | A experimental measuring system of double-illuminator method was used in order to study the history of collapse parameters include two dimensional Lagrange velocity and Taylor angle about two type of spherical liners, The final velocity, final Taylor angle and characteristic time of specified particles on inner wall of liners were measured . By comparison between theoretical and experimental result the conclusion that theoretical result is bigger than experimental was discovered. |
