It is doubtful that the diffusion or ideal mixing stage models can satisfactorily represent the behavior of gas in fluidized beds.
扩散模型或者理想混合级模型能否满意地表示气体在流化床中的性状是可以怀疑的。

Based on experimental results from a flume, a systematical study on the properties of sediment diffusion in turbulent mixing region at the mouth of cecum reach was made.
