The sizes of soil particles vary over a very large range. Depending on the predominant size of particles within a soil, it is generally referred to as being a gravel, sand, silt, or clay. Gravels are unconsolidated rock fragments produced by mechanical weathering with occasional particles of ...
As randomness is independent of sand types, only Hebei A is selected to determine the minimum number of images required to eliminate the Conclusions This paper proposes an automatic method based on deep learning to quantify the size and shape of particles from stacked sand particle images. ...
Particle size distributions of sand and dust are surveyed. Various assumptions for the theoretical prediction of the effect of particles on MMW propagation are discussed and justified. A general formula of the propagation parameters, for any particle shape and any distribution, is developed. It is ...
1.Influence of particle distribution of PTA on slurry properties;PTA粒度分布对其浆料性能的影响 2.The effect of silicon carbide particle distribution on extrusion paste's rheological property and green bodies' density were investigated by changing the volume fraction of different particles.通过改变物料组...
It is found that the microwave propagation mainly depends on the value of I3 /I2 and I4 /I2 relating to the particle size distribution. A simple relationship is shown between attenuation A and '' I3 /I2 , I4 /I2 '' of the sandstorms. Attenuation due to charged sand particles is ...

Fine particles with low sand contents from 3 to 17% were distributed in the conserved area of the Isahaya Bay Polder. The particle size distributions were classified as (C, II) and (D, II) and characterized as calm hydrodynamic conditions. Soils developed in the brackish lake, the Hachiro...
