And the application of AWJ is based on the hypothesis such as time mean and special grain shape, and is limited in studying the rule of gas-solid-liquid three-phase flow.
Res is the Reynolds number, v r, s is the terminal velocity correlation for the solid phase.

NA and NB are numbers of atomic planes of A and B in bilayered films, respectively and Xλλλλ is the wavelength of the X-ray.
This result suggests that atoms diffuse along the interface of Fe/Pt and/or the grain boundaries of Fe/Pt thin film.

Aggregate density of gross volume (g/cm3) Grain size /mm 16 13.2 9.5 4.75 2.36 1.18 0.6 0.3 0.15 0.075 Mineral powder Apparent relative density /g·cm-3 2.808 2.806 2.795 2.772 2.702 2.703 2.703 2.695 2.732 2.693 2.725 1.2 Design of mix proportion According to the related provisions in Criterion[5], the mix proportion of SMA mixture is designed like following: the admixture ratio of lignin fiber is 0.3%, while mineral fiber and mineral wool fiber are all 0.4%.
Section photos of SMA-16 If the mixture distribution is uniform, then each file size of aggregate whose location distribution and distributed number in each area section should be uniform too[11].

Mean grain size of the prior austenite was around 80µm in each steel.
Assuming that a large number of mobile dislocations exist in the as-quenched martensite and they move easily during tensile deformation, a considerable plastic strain could be produced even when the stress is under the level of macroscopic yielding point [7].

Smaller andmean that it is easier to nucleate, and the number of the primary particles increases.

Considering Fig. 5, the analogy to sifting grains with decreasing mesh openings of the sieves becomes clear.
In-situ three-dimensional microstructural investigation of solidification of an Al-Cu alloy by ultrafast x-ray microtomography, Metallurgical and Materials Transactions A, Volume 36, Number 6 (2005), p. 1515-1523 [6] N.

Maeshima et al. have studied SME of Ti-Mo containing Ag, Sn and Sc, and found the remarkable grain size refinement by Sc oxide [4, 5].
Although a limited number of peaks were detected due to a strong texture formation similar to TiNbAl [20], TiMoAl was judged to be two phase of bcc β + orthorhombic α" at RT.

Tab.2 the grain sizes of ZnO powders Sample 2θ/° B/° d/nm A 36.196 0.254 74.8 B 36.218 0.300 62.7 C 36.213 0.334 56.4 D 36.194 0.352 54.5 We can see that particle sizes decrease as the radios of urea to glycine decline.
(4) (5) Where n is the number of the mole, T is the adiabatic flame temperature, and Cp is the heat capacity of the products at constant pressure.

In some grain producing regions, statistics shows that the yield of maize was reduced by 11%-13%, wheat by 9%-10%, rice by 8% -14%, soybean by 5.5%-9%, vegetables by 15% -59% when the film residues reached 58.5kg/ha. [7].
It’s probably because there were a growing number of plastic nails formed at the beginning, which enhanced the dry bonding strength.

Then, the free ultimate coal particles settling velocity, up0 (it is termed uniform coal particles settling velocity when the resistance is equal to the gravity of the coal particle), can be calculated by the following equation[10]: (1) where g is the acceleration due to gravity, m/s2; d is the diameter of the spherical coal particle, m; ρp and ρf are the densities of the coal particle and the working fluid, respectively, kg/m3; and CD is the coefficient of resistance, which is a function of the Reynolds number of the coal particles.
The median grain diameter of the coal particles is 0.3 mm and the percentage of the coal particles with a diameter less than 0.5 mm is 90%.
