硕士论文：粘弹性介质地震波数值模拟。 震波在实际地层介质中传播与在理想的完全弹性介质中传播有许多不同之处，地层的粘滞性会损耗地震波能量，使其振幅衰减并且视频率逐渐降低。地震波的这种能量 衰减和频散，使得不能直接从地震数据上得到准确的地下信息和分辨率更高的图像。实 际的地层更接近于粘弹性介质，本论文主要探讨和研究了粘弹性介质中地震波传播的数 值模拟方法及其衰减规律。 (Thesis: viscoelastic medium seismic wave numerical simulation. The shock wave propagation in the formation medium and ideal perfectly elastic medium spread there are many differences, the viscosity of the strata will loss seismic energy, so that the amplitude attenuation and video rate gradually reduce. This energy of the seismic wave attenuation and dispersion makes accurate subsurface information and higher resolution images can not be obtained directly from the seismic data. Actual formation closer viscoelastic medium, this thesis is to explore and study the numerical simulation of seismic wave propagation in viscoelastic media and its decay law.)
