The extent of attenuation is proportional to the parameter under some assumptions in open channel flow . the lack of a sound theoretical basis for predicting the behavior of coarse particles means that experiments play a critical role 在明渠二维恒定均匀流条件下，经过适当简化和假定得到的结果表明，悬移质运动起到减弱流体紊动强度的作用，制紊作用随参数的加大而增强。
