Besides such approach provides the simple possibility of specification and expansion of number of the factors influencing the carbonization process at a sacrifice of correction or addition of corresponding dependences in: k k nB ii nB nV ii nV F F F F f )1(....)1( )1(.....)1( )( 1 1 11 11 α α α α ω +⋅⋅+ +⋅⋅+ = , (1) where )(ωf - the function of the technological and statistical parameters of burden as a result of which calculation change of parameter CRI is defined; iα, kn - the coefficients providing corresponding influence of the factor; iF - the actually factor (the characteristic of burden, parameter of coking conditions of, etc.).

., pseudo-grain-boundary [9].
Moreover, the number of oxygen defects likely represents the degree of non-equilibrium behavior in the films.

It first extracts a certain number of points set from target data randomly, then calculates them by certain mathematical model to find out those that meet the requirements, and finally gets the maximum points set which meet the requirements through operating such methods iteratively.[3,4] Image Fusion Algorithm.
In this paper, the size of diamond grain in grinding wheel is from 140 Mesh to 170 Mesh.

Introduction Nanoindentation is extensively used to explore the material properties in the sub-micrometer region, e.g. grain boundaries in metal or thin films on a substrate of opt-electronic devices [1, 2].
The molecular mass of a folded chain is 6724 while the total number of methylene group in the crystal is 268960.

Then the ignition grain is fired at assigned time and place.
One comprehensive defense system consists of number of airbag interception ammunitions.

Another important effect of the deposition pressure can be observed in the microstructural characteristics of the films: the ones made at 1 mbar are not fully compact being easily removed from the substrates, while those deposited at 2×10-4 mbar exhibited a large number of fractures due to the high level of residual mechanical stress.
In this particular case, the different stress levels and the nucleation and growth of the perovskite crystal lattice having particular orientations were most probably related to changes in the extent of Ti diffusion through the Pt grain boundaries during the deposition of the metallic films at different temperatures, as previously reported for PZT films made by RF magnetron sputtering [8].

The molecular chain of cellulose II has bad arrangement regularity, and the growth of crystal grain is not sufficient, thus the crystallinity index and degree of crystallinity of cellulose II have different decrease compared with cellulose I [8].
SEM pictures of the fiberss before and after degradation It can be seen from Figure 2, parts of the surface of cotton, ramie, viscose fibers are porous and grooved after degradation for 20 days; while the number and size of holes on the surface of the three fibers increase substantially after degradation for 40 days,meanwhile, the groove increases and the fragmentation phenomenon appeared.

Four rock types are Äspö diorite(31%), greenstone (56%), fine-grained granite(11%), and pegmatite(2%)[5,6].Four fracture sets are present.
The plane thermal-mechanical coupling geometry is a quarter circle generated by FLAC FISH grid generation tool with an inner radius of 0.875m and an outer boundary of 20m, and the total element number is about 2000.

Arun et al. [3] investigated the influence of grain size on the electrical properties of Sb2Te3 polycrystalline films.
As the film thickness increased, the number of diffraction peaks was increased.

Conversion Conditions of Grinding Mechanism for Difficult to Grinding Materials In Quick-point grinding process, both the grain depth of cut and the contact length is very little, and the process no longer generates debris at the brittle form completely for some brittle materials such as advanced ceramics because of impact and adiabatic shearing micro-damages, whereas the grinding mechanism is that the material is removed at ductility.
