运用有限差分法研究频率域中二维弹性波动方程组的正演算法及理论合成记录的制作。频率域中二维弹性波动方程组的建立还未见报道，且此种算法要比时间域中正演算法计算量小得多，大大提高了计算速度，并且为弹性波动方程组的多参数反演提供了基本保证。理论合成记录的制作是获取波场信息的重要途径，可以全面地反映地震波在地下介质中的分布与传播情况
Applying Finite Difference Method to Study Forward Algorithm of Two - Dimensional Elastic Wave Equations in Frequency Domain and Making Synthetic Records. The establishment of two-dimensional elastic wave equations in the frequency domain has not been reported yet, and the proposed algorithm is much less computational than the forward algorithm in the time domain, which greatly increases the computational speed and provides a multi-parameter inversion for elastic wave equations Provided a basic guarantee. The production of theoretical synthetic records is an important way to obtain wavefield information, which can fully reflect the distribution and propagation of seismic waves in underground media
