说明：  f-K偏移，是地震成像中用得较多的方法之一。(fK migration, seismic imaging is one of the methods used was higher.)

说明：   考虑幅值谱与相位谱的人造地震动模拟与反应谱拟合 我国对《建筑结构抗震规范》进行了修订，将设计反应谱周期由原来的3秒延长到现在的6秒。反应谱周期的延长。 本程序以新规范反应谱作为目标谱，采用三角级数迭加来模拟地震动加速度。(consider amplitude spectrum and phase spectrum of the artificial seismic simulation and pattern fitting response to China's "structural seismic code" the amendment to the design spectrum cycle from three seconds to extend the current six seconds. Response spectrum cycle extension. The new procedures to regulate spectrum as the target spectrum, the use of triangular series superposition to simulate vibration.)
