A significant number of data points were obtained with both benzoic acid and 2-naphtol and, in Figure 6, they are shown to be in excellent agreement with Eq. (26).
Also in the understanding of certain mineralogical processes, such as the dissolution of plagioclase grains, during diagenesis (see Stoessell, 1987 and Phillips, 1991), modelling of the transport of aqueous Al by diffusion and convection around the grains may be required.
A large number of experimental data are available (Guedes de Carvalho et al., 2004) to confirm that Eq. (28) predicts the rate of solute transfer with great accuracy.

Mass transport in sandstones around dissolving plagioclase grains.

As can be seen from negative cumulative curve, such coal has high material content of fine grain size.
Material content of 0.074mm grain size reaches 38.63%, and material content of -0.045mm grain size takes up 7.07%.
Graded flotation is carried out according to different characteristics demonstrated by coarse-grained and fine coal slurry[3].
Coarse grade and fine grade level after grading are respectively separated and overflow flows into appropriate fine-grained flotation separation system and bottom flow into appropriate coarse-grained flotation separation system.
Grade level after the coarse grinding process of re-separation is better than full-grain-level direct sorting into the floating craft.

The corresponding dark field (DF) image reveals a nanometer scale grain size.

Particularly the rings denoted with the numbers 2, 3, 5 and 7 were found to correspond to (111), (200), (220) and (222) TiN Bragg reflections, respectively with fcc cubic structure.
Rings denoted with the numbers 1, 2, 4, 6, and 7 are the same with Fig. 5c and correspond to AlN.
Apart from the previous areas where all the formed grains are nanosized, there were a few particular areas where the size of the existing grains was remarkably higher.

Their variation is due to the number of experimental tests taken into account for their identification and obviously to the thermo-mechanical path.
The aim of the present work is to study the influence of thermo-mechanical treatments of two IFTi steels on the stored energy values as well as the number of mechanical tests used for the identification of the behaviour law parameters.
The first material was only hot rolled, and its grain size is about 75 µm.
NDRDThe microstructure has been determined on the first material and it is assumed to be locally representative of the second one since the grain size is not an important parameter in the ABAQUS calculation.

Introduction A large number of studies have been devoted to multiphase nanocomposite coatings obtained by ion-plasma jet deposition of multicomponent materials.
It was established by X-ray diffraction analysis that there was the TiAlN phase in the initial coatings with the preferred orientation of grains (111).

However, there has been a small number of research studies regarding the corrosion for decorated surface by fiber laser.
The grain refinement can be seen under the laser-treated surface approximately 10 µm depth.
The grain size can be significantly reduced when power density that is performed on the surface increase [6].

Refer to Kwok et al. [19], the study evidenced that the pitting resistance increase with the decrease in grain size.

Brittle fracture is transgranular fracture along the cleavage surface or intergranular cracking along the grain boundary, there is no visible deformation characteristics.
The tooth number of the pinion is 18 and the tooth number of the flange is 216.
Grain size is consistent, the fracture is a S line.
When we increase modulus without changing the center distance , tooth number must be reduced.
The scheme is increasing the module of gear, reduce the number of teeth and use the positive displacement, but it slightly changes the transmission ratio.

In this paper, polymer chains of Nafion membrane are represented by coarse-grained model, in which each mass point corresponds to a group of atoms such as CF, CF2, CF3.
The number of the group of monomers shown in Fig. 1 is prescribed as , .

All the simulations are done using the coarse-grained molecular dynamics program OCTA/COGNAC [7].
Simulation Results To calculate the density of the component substances of Nafion membrane at the given point inside the unit cell, the unit cell is divided into several grids and the number of the divisions at each direction is 18.

Previous investigations have revealed that when USV is applied on the solidifying melt, microstructure changes occur involving grain refinement, increased homogeneity, reduced micro-segregation as well as degassing [3-5].
There are not as many published researches on ultrasonic treatment of magnesium alloys as on aluminum alloys, and most researches on ultrasonic treatment of magnesium alloys were focused on grain refinement[8-10].
First, the number of nuclei and particle growth rate increase with increasing cooling rate, which makes the solid volume fraction of AZ61 slurry increase.
