With a large number of modern new materials developed by research, the prospect of the industrial product design is broader and the value of industrial products, further enrich and improve.
The beauty of materials mainly through the material texture itself, namely grain, structure, luster and texture features [2].

With varying of mesh number of the stainless substrates, their Fe2O3 nanowire structures are systematically characterized.
The smaller wires had a significant effect on the smaller grain or seed size of the stainless steel, which had an impact on their diameter of the nanowires.

The XRD pattern of nanowires on the mesh number 60 was shown in Figure 4.

In this article, The number of input layer’s neurons is equal to number of input parameters, but the output layer has only one neuron, namely concrete strength.
The number of hidden layer and its neurons decide the model’s superiority.
Best number of neurons in hidden layer should be between 3 ~ 13 [16].
Design of mixture ratio of pottery grain concrete[J].

Results and discussion 3.1 EL observation First, defects are classified into five types as shown: A – over-soldered, B – cracks on cells, C – as-grown defects, D – grain boundary and dislocation dense area, E – cutting damage.
(Hereafter expressed as TC-number.)
The number in the parentheses refers to the undamaged module number in a group. 4.
Only a small number of cells were observed to have new cracks as the number of TC cycles increased.
These cracks were not visible until the cracks enlarged as the number of TC cycles increased.

As the ODF representation method appeared primarily in an approximation, it was defined as the series of a reduced orientation distribution function (R-ODF) for crystalline grain clusters, which merely consists of the even-number item of ℓ and can be solved by the series expansion method (SEM) through pole figure data measured; furthermore, with the development of quantitative texture analysis, it finally evolved to the complete orientation distribution (C-ODF) through some specific mathematical treatments.
With application of PSO, let ‘I’ be the particle number, and they are randomly allocated with the initial positions and corresponding values of velocity.
When Eq. (5) is substituted into Eq. (3) and Eq. (4), a set of nonlinear equations on solving different l whose total number is (R+1) are obtained.
(a) Constant-Φ sections of C-ODF (IF steel) using PSO corresponding to sample A, and the iteration number: k =500.
(ωmax=9.31), it has been obtained after 5000 iterations, whose number is ten times over that derived from PSO.

High-energy ball-milling in hexane medium was employed to prepare noble Zr-based bulk metallic glasses (BMGs) alloy of three different nominal compositions Zr47Be23Ni15Ti15, Zr50Be20Ni15Ti15 and Zr52Be18Ni15Ti15, numbers indicate at.%).
A number of papers [1,3-5] on the study of metallic glasses show the amorphous state is altered by structural relaxation and crystallization processes.
Samples milled for 50 and 300 h contain a large fraction of Zr grains, as can be seen from the FCC Zr peaks, which are high in intensity and exceed the halo in height (see Fig. 4(b and c)).
(i) a high number of, (ii) a large atomic size mismatch between and (iii) a high chemical affinity between the constituent elements.

Grain size is condensed, refined and compacted surface is smooth, harden and layer wearing than ground or honed surfaces [13].
When the number of passes increased, the surface roughness decreased.
The number of time the burnishing tool passes, the surface is subjected to hardness.
As number of tool passed many time, the circularity increased at low spindle rotation than at high rotational speed.
This was due to number of time tool passed.

It is worthy noting that a large number of small Fe particles may be produced in pure water solution in Fig. 2a.
Several new diffraction peaks are observed in sample b at 2θ = 44.35◦, 64.53◦ and 2θ =36.17◦, 38.07◦, corresponding to Fe phase and Fe2O3 phase, which grain size was calculated to be 15 and 20 nm for Fe3O4 and Fe.
These grain sizes are larger than the core sizes of samples a, which are coated by Fe layer.

During the developing process, some CsCl dissolve in the water on CsCl film, forming small grains.
As time goes on, the adjacent smaller grains assemble together to form larger ones following the principle of lowest surface energy[12].
