说明：  Randon data from program

说明：  声波方程正演模拟大模型样例。 包含三个地质层，分别对应速度可以自行修正。 震源函数是雷克子波。 C源程序，输出结果Matlab绘制。(Acoustic wave equation forward modeling big model of the sample. Consists of three geological layers, corresponding to the speed you can correct itself. Lake wavelet source function is. C source code, the output of Matlab draw.)

说明：  蒙特卡罗方法可以有效地解决复杂的工程问题，而MATLAB具有强大的数值计算功能。将二者结合使用，可以得到高效的解决问题的方法。本文阐述了该方法并通过实例验证了该方法的正确性和优越性。 (Monte Carlo method can effectively solve complex engineering problems, and MATLAB has powerful function of numerical calculation. The two in combination, can be cost-effective solution to the problem. This paper describes the methods and examples of the method to verify the correctness and superiority.)
