基于Peltier等建立的粘弹地球表面负荷形变理论，运用简正模分析法，实现了SNRVEI粘弹地球模型表面负荷勒夫数从拉氏域至时间域的变换．数值结果印证了韩大仲关于真实地球存在“连续分布的简正模”的结论，同时还表明在保证较高计算精度前提下，为便于计算，将地球核慢边界以上部分划分成较少个物性均匀层是可行的．本文的方法和结果经过数值检验，可用于冰后相对海平面变化、地球自转非潮汐加速度变化等地表负荷均衡动态响应观测量的研究．
Based on the theory of surface deformation of viscoelastic earth established by Peltier et al., The transformation of Laplace domain to time domain of the surface load of the SNRVEI viscoelastic globe model is achieved by using the simple normal analysis method. The numerical results confirm the conclusion that Han Dazhong has “continuous normal modes” for real earth. At the same time, it is shown that for the sake of calculation, the above part of the slow boundary of the Earth's nucleus is divided into less homogeneity layers It works. The method and result of this paper are numerically tested and can be used to study dynamic response of surface load balance such as relative sea level change after ice and non-tidal acceleration of Earth's rotation.
