| 摘 要： | 地球介质非完全弹性参数对于研究地体稳定、地震孕育、地幔对流、大陆动力学是 非常重要的．在精确的工程勘探、油气勘探中也是一个不可缺少的参数．为了用实测的地震 体波确定非弹性参数，本文从一般线性流变体介质内波动方程出发，导出了由观测的地震波 体波波速和振幅确定一般线性流变体介质内虎克定律系数的两种具体方法及其相应的理论 公式，并给出了体波振幅法的一个模型实例．在线性近似下，这些参数可确定地球介质的非 弹性性质．

| Abstract: | It is very important to use noncomplete elastic coefficient to study massif stabilitty, earthquake gestation, mantle convection and continent dynamics. Anelasticity parameters are also necessary for high resolution exploration of engineering and oil and gas. In order to Probe nonelastic parameters using observed seismic body waves, on the basis of wave equation in medium with linear rheological property, two methods and corresponding theoretical formulaes are given, which can determine the parameters of medium with linear rheological property from observed seismic wave velocities and amplitudes. At some time the paper shows model model result using body wave amplititude to probe anelasticity coefficients. These anelasticity coefficients can determine the nonelastic characteristics of earth medium with linear supposition. |
