The results show that the turbulence intensity, fouling cleaning intensity and pressure drop increase with the increase of flow velocity, particle size and the volume fraction. The effect of liquid-solid fluidzed-bed cleaning fouling depends on the reasonable combination of flow velocity, particle size and the volume fraction. Through an integral consideration of water saving and energy saving and uniformity of fouling cleaning, the optimum flow velocity of flow, particle size and volume fraction are 2.0 m/s~2.5 m/s, 3 mm~4 mm and of 5%~8 vol%, respectively.

At constant viscosity, by increasing the liquid flow rate, the liquid film's velocity is increased; at the same experiment condition, the frequency of the liquid film is same at the same radial direction; the air current has minimum effect on liquid film bottom flow velocity, while it has an obvious effect on liquid film surface flow velocity. The longer the distance between liquid film and the inlet, the lower the pulsatory frequency and longer the wavelength.

在粘度基本不变的情况下，随着液体质量流率的增加，液膜流动速度随之增加；在同一个实验条件下，沿圆管径向各质点的频率基本保持不变；气流场速度对液膜底层流动速度影响很小，对于液膜表面流动速度有着较大的影响；沿液膜流动方向，液膜的脉动速度逐渐增加，脉动频率降低，脉动波长变长，与报道的通过快速摄像得到的液膜发展趋势一致，证实用PDA研究液膜流动是可行的。

It has an electric field with the same order as that of the SKAW on the Alfvén velocity branch, but its magnetic field is weaker than that of the latter by a factor of (β/2)1/2=Cs/νA, where Cs and νA are, respectively, the ion-acoustic velocity and the alfvén velocity.

它具有一个与阿尔文分支上SKAW同一量级的扰动电场，但扰动磁场比后者低β1/2倍。

The field experiments on the near surface airflow, sand transport rate, grain size of the dune sands and the morphology of the dunes show that though shear velocity decreased at the toe of the transverse dune, the threshold shear velocity decreased simultaneously. The decreased threshold shear velocity and unsaturated sand flows at the stoss slope of the dunes resulted the erosion at the toe of the dune.

对简单横向沙丘表面的气流、输沙率、物质结构，以及形态学特征的观测表明，在横向沙丘迎风坡坡脚尽管剪切速度有所下降，但起动剪切速度同时减小，起动剪切速度减小与不饱和风沙流是沙物质在迎风坡坡脚不能产生沉积的主要原因。
