| 摘 要： | 视地幔为牛顿粘滞层状流体,根据流体力学导出地幔流体动力学基本方程,并以此通过对重力场和岩石圈底面地幔流应力场的研究,得到两种力场的重要关系,从而获得利用地面或卫星重力资料确定岩石圈底面地幔流应力场的新公式。文中从详细推导到结论分析说明了该公式克服了Runcorn模式的三个缺陷。

| Abstract: | The basic equation of hydrodynamics of mantle fluid was deduced with the hy-dromechanic theory based onthe hypothesis that the mantle is a laminar viscous Newtonian fluid.According to this equation the author have studied the gravity field and stress field of mantlecur-rent in lithospheric base and derived the relationship between these two fields, furthermore, anew formula to determine stress field of mantle current in lithospheric base by surface and satel-lite gravity data was obtained. It is still showed that the new formula can overcome three short-comings of Runcorn's pattern. |
