balance. 1.3 Formula design In order to reduce the number of test, L9(34) orthogonal table was selected for orthogonal test,and the interplay between each factor was left out ,shown in table 1.
Fig.5 Size distribution chart of rutile titanium dioxide 2 Grain size range of rutile titanium dioxide 2 is from 0.082µm to 0.088µm,coating made with this sample has reflectivity of 66.70%.
Pigment grain size has main effect on the coating reflectivity as soon as the pigment selected.
(3) Grain size analysis showed that pigment has maximum reflectivity when grain size range is 0.107µm~0.687µm

When the sintering temperature was 1000 ℃, the average grain size of the crystal particles was 100-200 nm and the thickness of the thin film was about 380 nm when the coating layer number up to 10.
While the sintering temperature was 1100 ℃, the average grain size of the crystal particles was 200-300 nm and the thickness of the thin film was about 320 nm also 10 layers.
Analysis with the coordination number of A-type LSO and B-type LSO from Table 1, the reason why the thin film became much more thinner under 1100 ℃ was that the coordination number of B-type LSO became lower and the reengineering of the organization structure[9].
The thin film was of average grain size of 100-200 nm at 1000 ℃, besides, the thickness was of about 380 nm when the coating layer number up to 10.
While the average grain size was of about 200-300 nm at 1100 ℃ and the thickness was of about 380 nm.

In these the phenomenon of "ridging" or "roping" is often observed, leading to the discarding of a large number of parts and raising production costs.
For steel 434, Fig.2b, layers of large, heterogeneous grains near the central plane of the sheet sandwiched between regions of smaller grains can be seen.

The coarseness of the pattern will depend on the colony width and grain size.

The number in the figure is the strains estimated by assuming the homogeneous deformation.

Unlike base metal that has coaxial grain structure, weld metal is composed of a dendritic structure.
Grain growth in the heat affected zone did not occur.
Final microstructure and mechanical properties of weld and heat affected zone will depend on the heating and cooling rates and the number of times a particular region experiences the thermal cycle.
Grain growth in the heat affected zone has not happened, but very small precipitations have deposited.
Some precipitations have been deposited at grains and grain boundaries of heat affected zone.

It is also obvious that the number of primary α-Mg in the slurries increased by UV.
Because of ultrasound and cooling impact stemmed from the chilling mold, huge number of nuclei still exist in the remnant liquid.
The decrease of APD and increase of primary α-Mg grains result in fine grain boundaries and second phase in the semisolid Mg alloy.
It can be seen that the bright phase in gravity casting alloy distributes nonuniformly and a number of coarse blocks concentrate at the junctions.
The remnant liquid is divided into huge number of small molten bath by the fine α2-Mg grains, and the growing space for LPSO structure is limited to poky intergranular areas.

The purpose of the research is to determine the effect of a mixture of water of different structure on the strength of fine-grained concrete and the speed of its formation.
However, the availability of such cements "on hand" in a significant number of cases is significantly limited and requires a solution to the problem of organizing their search and transportation in sufficient quantities.
The problem lies in the clearly insufficient number of existing methods of calculation, construction and organizational and technological measures to ensure the stability of concrete.
Aim of Paper The purpose of the research is to determine the effect of thermally activated water on the strength of fine-grained concrete and the rate of formation of its structure.
Shishkin, Research into effect of complex nanomodifiers on the strength of fine-grained concrete.

When the extrusion temperature is 1080℃, there is still some region of unrecrystallization, but the number of fine recrystallization grain become more.
The recrystallization grain is very fine and grain size is about 4～5μm.
Some finer recrystallization grain lie the uniform grain and the grain size is about 1µm.
The γ' phase lie the grain boundary inhibit the free growth of grain.
When the heat time reach 90min, some grain with γ' phase is still fine, but little grain without γ' phase grow rapidly and grain size reach 8µm.

With K2CO3, SrCO3 and Nb2O5 starting materials, KSN lead-free piezoelectric ceramics were prepared by conventional ceramics technique and reactive templated grain growth (RTGG) method, respectively.
The KSN ceramics prepared by RTGG not only had higher degree of grain orientation but higher sintered density compared with that prepared by solid-state reaction.
Simultaneously, a large number of pores are observed in the KSN ceramics.
It is confirmed that KSN lead-free piezoelectric ceramics with higher degree of grain orientation and sintered density could be prepared successfully by RTGG methods.
The KSN ceramics prepared by RTGG technology not only had higher degree of grain orientation but also higher sintered density compared with that prepared by traditional solid state reaction.

Also nano-structured Dy doped CeO2 sintered bodies in the present study had wide ionic domain and high transport number of oxygen.
The average grain size in the sintered body was calculated using the linear intercept method measuring more than 200 grains using SEM.
The ionic transport number of oxygen, ti, was estimated as a ratio of observed emf to the theoretical emf.
The conductivity decreased with decreasing grain size and reached the lowest value at an average grain size of 237nm.
The n-type conduction appears because the number of conductive electrons is increased by a reduction of CeO2.
