摘要
根据物体运动的摩擦力定律和物体变形破坏的库仑定律对牛顿内摩擦定律作了改进 ,进而改进了达西定律。用改进的达西定律与实验资料进行拟合 ,阐述了达西定律与实际偏离的原因。
Newton's Law of viscosiy is improved according to the Friction Law of motion and the Coulomb's Law of deformation and disrupture of object,and the Da rcy's Law is improved.The improved Darcy's Law is fited with the test data,the r easons for deviation of the Darcy's Law to the test data is illustrated.
