In view of the two-dimensional wave equation, we have studied an example, the wave equation of the elastic film. Its physical meaning is: grasping the two position, the elastic film were filed to form the two peak in the film, t=0 moment suddenly let go, according to the common sense of life can be expected, the two position of the film back to the future shock, at the same time the wave propagation and wave and the wave will be at the meeting point superposition. Programming with MATLAB and visualizing the process.
