A unique homogenized microstructure comprised of fine particles grain size was obtained which totally differs from that obtained by ordinary casting.
Both the tensile strength and elongation closely connect with the particle grain size and cementite network changed with fraction of solid.
Because the oxide skin is produced during the reheating process will cause defects when it fills the die cavity, in semi-solid die casting the most important factors are the filling velocity, the area of the gate, and the position, size, the number of overflow.

The authors hope that under the years of work on Lanping-Simao Basin potash deposit, especially systematic study and the summarized experience gained in the Mengyejing-type potash deposit, we can extract the direct and indirect information about potash deposit from the large number of geological, geophysical and geochemical exploration, remote sensing, and computer information from prospecting.
Upper segment (transition beds) is brown-red silty argillite, calcium muddy siltstone with a small amount of fine-grained siltstone and containing secondary gyps with 13~509m thick.
Lower segment(potash containing segment) is brown-red, celadon, variegated muddy conglomerate, siltstone, dolomitic argillite and small amount of fine-grained siltstone, anhydrite, containing distributed salt springs, and halite, sylvite, anhydrite containing argillite, siltstone and marl in deep part, 9~682m thick, conformable contact with lower Mankuanhe formation.

In these experiments are evaluated mechanical properties of coatings, chemical composition, corrosion resistance, and also a number of other properties.
Optimal flight speed of abrasive grains is 80 m.s-1.
This rate corresponds to the rate of abrasive grains in the equipment used in practice.

However the later result is larger than the former one, it is because some of nano-materials exist agglomeration, including soft agglomeration appears between the two grains (mainly due to the effect of electrostatic attraction among nano-materials caused by surface charge) and hard agglomeration among Multi-grains (in the gelation process, van der Waals forces causes a chemical bond between the nano-materials connection).
In the figure, a number of atomic vacancies are obviously existed.

Both of them showed a rough surface with the 3D islands, however, sample (b), starting with ZnO layer, consists of smaller grain size, therefore show a smoother surface than that of sample (a)，suggesting that different sequence of SLBLs will affect the morphology of ZnO films.
consists of much larger grains and exhibits a rougher surface than the film grown at the low O2 pressure of 8.0×10-6mbar, suggesting that the O2 power results in higher roughness with increasing O2 pressure.
However, the Raman analysis showed a shift to lower wave number of E2 (high) peak for every sample, compared with ZnO single crystal, implying that a tensile stress occurred in all samples, which was also proved by the XRD spectrum.

Introduction Soil salinization had serious harm in inland saline areas, which were limited grain production and the grain yield was only 25% -40% compared with high-yield field [1-2].
The domestic and foreign scholars had done a lot of research for the study of the use of saline-alkali soil improver, which founded that the Soil amendment can improve soil properties to a certain extent, reduce soil salinity and pH [3-5], but it just played a role on the surface soil, did not prevent the salt gathered a large number to the surface that results from the increase in shallow groundwater, soil evaporation and other factors, which seriously affected the growth and yield of crops, thus weakening the effect of the modifier [6-7].

We express sincere thanks to number of organization such as DSI Inc, USA, Trans Tech Publishers and CBMM, Brazil for supporting student participation.

The viscosity of isopropanol is higher than that of ethanol, so number of TiO2 nuclei in isopropanol system is less than that in the ethanol system, which led to grain size of TiO2 powders using isopropanol as the oxygen are smaller and easier to agglomerate than that of TiO2 powders using ethanol.
On the other hand, charge recombination and electron transport limitations become more significant because of the longer path of injected electrons across colloidal particles and grain boundaries, so the FF decreased with the increasing of thick.

The SiC deposit condenses on the graphite as a coarse-grained coating up to 10 mm in thickness.
According to our observations, continuous product layer between carbon and silicon produced after diffusion-limited growth mechanism can only be found in quiescent melt (for example inside a narrow capillary channel) and Journal Title and Volume Number (to be inserted by the publisher) 3 only if small-grained graphite with porosity of 5-10% is used.

Since there are no grain boundaries, the nickel-base single crystal superalloys eliminate the void-damages localized at grain boundaries.
