摘　　要：在流体力学的流体连续介质模型的基础上,引进渗流体质点的概念,建立了一种新的渗流体连续介质模型.从新的连续介质模型出发,导出不可压缩牛顿流体在各向同性多孔介质中流动的渗流基本方程.The concept of the fluid particle in porous media is introduced and a new continuum model of fluid in porous media is established in the paper, based on the continuum model of fluid in the fluid mechanics. Then the fundamental equations of the incompressible Newton fluid flowing in the isotropy porous media are derived according to the new continuum model.
