在对在复杂的非均匀构造地震勘探中所采集的数据作正确的解释时,必须经常考虑弹性效应弹性波方程的应用是为了模拟假想地质构造的地震响应,这对于阐述观测到的地震数据与大地非均匀性的关系,以及验证解释结果来说,是一种有价值的手段。有几种方法可对描述弹性波传播的偏微分方程作数值积分。虚谱(傅里叶)法是一种先进的数值积分技术。它们的主要优点是精度较高并适应于向量型和平行计算机结构特征,而它们的主要缺点是计算费用很高然而,对于给定的精度来说,虚
In order to correctly interpret the data collected in complex heterogeneous structural seismic surveys, the application of elastic-elastic wave equations must be frequently considered in order to simulate the seismic response of hypothetical geological formations, which is of great importance in explaining the relationship between the observed seismic data and The relationship between the heterogeneity of the earth, as well as the verification of the interpretation of the results, is a valuable tool. There are several ways to numerically integrate a partial differential equation describing elastic wave propagation. Virtual spectrum (Fourier) method is an advanced numerical integration technique. Their main advantages are higher accuracy and adaptation to vector and parallel computer structural features, whose main drawback is the high computational cost. However, for a given accuracy, virtual
