摘　　要：以地幔蠕动、热能聚散假说为指导，阐述了地幔蠕动的动力机制，并在综合分析多种影响地幔蠕动动力因素的基础上，依据牛顿粘滞性流体力学和塑性力学的基本原理，建立了地幔蠕动的数学模型，讨论了数学模型的数值方法。In the paper, under the theoretical guiding of the hypothesis of mantle creep, convergence and divergence of heat energy, dynamic mechanism of mantle creep is expounded,and based on synthetic analysis of many factors affecting mantle creep, according to basictheory of the viscosity hydromechanics and plastic mechanics, mathematical model of the motion of the mantle is proposed. Numerical method for computing mathematical model is discussed.
