Description: 针对二维波动方程，我们研究了一个实例，即弹性薄膜的波动方程。 其实际物理意义是：两手抓住弹性薄膜的两个位置，分别提起，使薄膜上形成两个峰，在t=0时刻突然松手，根据生活常识可以预料，这两个位置的薄膜将来回震动，与此同时产生的波向四周传播，而且波与波会在相遇处叠加。用matlab编程并将这个过程可视化。(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.) Platform: |

Description: 本章先分析说明伪谱法求解波动方程的算法原理，再给出弹性波场伪谱法数值模拟的改进算法；然后，通过直接引入P波波场变量和S波波场变量，给出可实现弹性波场的P波和S波分解的波动方程，并用伪谱法实现弹性波场的P波和S波分解的数值模拟；最后用伪谱法对井间地震的复杂波场作数值模拟，分析井间地震波场中各种波的传播规律。(In this chapter, the principle of pseudo-spectral method for solving wave equation is analyzed, and then an improved algorithm for numerical simulation of elastic wave field is given. Then, by directly introducing P-wave field variable and S-wave field variable, the wave equation which can realize P-wave and S-wave decomposition of elastic wave field is given, and the P-wave sum of elastic wave field is realized by pseudo-spectral method. Numerical simulation of S-wave decomposition; finally, pseudo-spectral method is used to simulate the complex cross-well seismic wave field and analyze the propagation law of various waves in cross-well seismic wave field.)
