A grain size distribution plot is a special purpose graph generally used to depict the results of a sieve analysis, commonly known as a "gradation test". The sieve analysis determines the gradation (the distrib
Cracked fragments and mature gouges can be differentiated on the basis of the slope D on a log–log plot of the grain size distribution. Both types of fault rocks exhibit two slopes: for grain sizes < 2μm, D ≈ 1.0 for both types; for grain sizes > 2μm, cracked material shows D...
This can be reflected on a grain size distribution (GSD) plot. The GSDs of many geomaterials show a self-similar (fractal) distribution (Perfect and Kay, 1995). Researchers demonstrated that the breaking up of larger clusters/particles by mechanical actions results in smaller clusters/particles, ...
rationalisation of strain anisotropy in terms of the modified Williamson-Hall plot [22]: 'K # D/D + (STb 2 /2) U /2 K 2 C + O(K 4 C 2 ) , (5) where 'K is either the FWHM or the integral breadth of profiles, D is the so called apparent size parameter, D is 0.9 or...
which is assumed to be the median grain size(d50)of the porous medium. However, numerical and experimental studies show that flow resistance in porous media is largely determined by the geometry of the pore structure. In this study, the effect of the grain size distribution was analyzed using...
Grain size is a key component trait of grain weight and yield. Numbers of quantitative trait loci (QTLs) have been identified in various bioprocesses, but there is still little known about how metabolism-related QTLs influence grain size and yield. The c
Where d is the Average distance of accumulation frequencies with sediment grain-size; P is the accumulation frequency of sediment grain-size in a certain sample plot; \(\overline{P}\) is the average accumulation frequency of sediments grain-size in different sample plot; K-1 is freedom degree...

Introduction Grain-size distribution analysis is a sedimentological approach for determining the size of the mineral grains that constitute a clastic stratigraphic unit....
Large-aspect-ratio grains are needed in polycrystalline thin-film solar cells for reduced charge recombination at grain boundaries; however, the grain size in organolead trihalide perovskite (OTP) films is generally limited by the film thickness. Here we report the growth of OTP grains with high ...
