A group of 60 people is invited for investigation on four aspects: GUI Impression, Operability, Event Richness, and Helpfulness, as shown in Table 3, where each item is the number of votes.

Number of scientific papers are dedicated to the consideration of different methods of laser cladding, theoretical research and development of mathematical models of related thermal and hydrodynamic processes.
The number of Re jet during cladding lie within 102-103, and Mach number is within 0.01-0.3, it allows to ignore the influence of viscosity and to use the approach of potential flow. 3.
At the fusion line is observed the growth of the solid phase from molten grains of base metal.
At low cladding speed the energy input in the coat is big enough, that leads to more overheating and generation of coarse grain structure in the field of mixing, similar to the structure of substrate and with the low increase of microhardness (Fig. 5).

The dependence of the load and test temperature on the friction factor is investigated by tests number 2 to 5 which have been realized using a 60 rpm continuous rotation movement during 30 min.

A grain reorientation is well demonstrated by pole figures (Fig. 11 and Fig. 12).

With the incorporation of Br- into the films, the number of pinholes increased.

Since then, ultrasound has been used in a number of areas of polymer chemistry.
DTG curve for 300 minutes sonicated PMA Grain Size and Roughness Atomic force micrographs give surface morphology of the sample, which is an indicator of the internal crystal or molecular perfection.
From the AFM scan of the area of the order of (nm)2, one can get information of the nature of the polymerization process, the average size of the grains, and the surface roughness of the sample.
In the process of sonication at smaller periods the roughness is large and the grain size is also large because of the increase in the molecular weight of the polymer (figures 8a, 8b).
At relatively higher sonication periods the roughness is small and the grain size is also small because of the high homogeneity found in the nature of ultrasound when passing through liquids and solids.

It can be also supposed that there is a strong correlation between the grain size of the delta ferrite and the austenite.
The grain boundary surfaces formed at the connecting delta ferrites can move, that manifest in the flattening of the curved boundary surfaces and perhaps in the coarsening of the delta ferrite crystallites (grain boundary surfaces are decreasing).
The observed zones: • The outer fine grain zone could not be identified, • Columnar zone, • Equiaxed zone with 40 mm total thickness.
The figure clearly shows that, MnS inclusions precipitates in solid phase at the austenite grain boundary if C>0.1%.
• By the help of quantitative metallographic measurements we demonstrated that the maximum number of MnS inclusions exists in columnar to equiaxed transition zone

Hence, for a given application, performance is defined by a number of electrical and optical but also by physical and chemical properties.
Grain boundary scattering and ionized impurity scattering are generally considered to be the two main interacting mechanisms in conductivity.
The bulk properties of TCMs such as conductivity and absorption depend on the crystallite grain size which increases with increasing film thickness.
Thus, compared to a pure undoped TCO, a larger number of electrons will participate to the circulation of the charges yielding to an increase in conduction by doping.
It was noted that for a temperature of 300°C the average grain size was about 10 to 25 nm, whereas it increases to reach 15 to 50 nm for higher temperatures.

Since the node number of 3D mesh is still larger, large scales equations solving method-element by element method and others efficient measures were adopted.
To reduce the unnecessary number of elements and to guarantee the calculation is performable, element type transition in the space must be carried out.
The total elements amount of DongQing CFRD is 19,231 and the total nodes number is 20,152.
Constitutive models 3.1 coarse–grained material constitutive model Nonlinear elastic Duncan-Chang E-B model [3] which widely used in China is adopted to simulate the behavior of Rockfill materials.

The process from Ca(H2PO4)2 to CPP, as a polycondensation reaction, has been researched to evaluate the number average degree of polymerization.
The number average degree of polymerization can be calculated by the water loss amount during the polymerization reaction.

Step A means the crystalline hydrate calcium dihydrogen phosphate losses its crystalline water; step B means the calcium dihydrogen phosphate dehydrates inside the molecule, then the product is A: B C C: B: 60 80 100 120 0 20 40 60 80 100 120 140 160 180 170 144 80 Strength (MPa) Average number polymerization degree calcium pyrophosphate(CaH2P2O7); step C means the calcium pyrophosphate dehydrates outside the molecule, then the polycondensation reaction happens and the polymer chain of CPP is generated.

The Ti-adsorbed ZnO (1120) surfaces have metallic characteristics because of the number of outer electron transferred from Ti to O is extremely limited and the area of negative charge of the surface is large.
In general, the segregation properties of the transition elements applied on the ZnO surface also determine the metal-ZnO contacts [4-6] and conduction properties of grain boundaries [7].
However, the (1120) surfaces is constituted by the chain of Zn and O consisting of alternating and the ditches in the [0001] direction, the lattice plane which perpendicular to the (110) direction includes the same number of Zn and O atoms, and all are parallel dimer exists in ZnO.
Each atoms on the surface lost one position in four-coordinated, and thus become a three-coordinated, and it bonding with one atom of the surface and two atoms of the sub-surface. the results of this paper indicate that the geometry of (1120) surfaces is similar to bulk phase, their surface relaxation is small, and(1120) surfaces relaxation, the number of bonding and the number of dangling bonds is same in this two surface, but the surface structure is different, M.Calatayud [8] think that is due to (1010) plane shear needs to be rotated 18°, but (1120) surfaces needs to be rotated 34.6° caused.
Ti-O shows obviously better performance than Zn-O in covalent bond. the Ti-adsorbed ZnO (1120) surfaces have metallic characteristics because of the number of outer electron transferred from Ti to O is extremely limited and the area of negative charge of the surface is large.
