【Abstract】 This paper mainly discusses the issue of cavity probed by means of elastic wave in panel medium.According to the time-observed data given in the exercise problem,then the related C language is programmed,the distributed area of low velocity is spotted as well as the position of cavity based on the best way with a restrained condition,mainly the nonlinear Monte Carlo Method and Simulated Anneal Method for working out the best scattered velocity field.Meanwhile,this paper discusses how to reduce wave source and acceptor on condition that the position of cavity can be determined.更多还原
