根据粘性流体的非滑移条件，建立了非絮凝均匀沙群体沉速计算式．经验证计算结果与试验资料吻合较好，并具有适用范围广、精度较高的优点
According to the non-slip condition of viscous fluid, the formula for settling velocity of non-flocculation uniform sand was established. The calculated results are in good agreement with the experimental data and have the advantages of wide range of application and high accuracy
