The effect of silicon contained in iron alloy substrates subjected to the process of zinc-coating in the conditions of metallization (440-460°C) has been explained a number of times [1-7].
Low solubility of silicon in phase z leads to its segregation at the border of grains and formation of areas of liquid Zn between z crystals [6].

It will create the most suitable environment for plants thereby to increase the grain yield and revenues.

Introduction Zn-Al-Cu type alloys are characterized by a number of advantageous properties which include: good castability, good tribological properties, low energy for shaping the product.
The main alloying element is aluminum [3], its addition increases the castability, influences the size reduction of grains and improves the mechanical properties [5].

The cellular composites used in the present study are manufactured from glass foam granules with the grain-size fraction of 12 mm supplied by Dennert Poraver GmbH, Germany.
Specimens tested at 1 Hz and at 20 Hz test frequency fail after approximately the same number of cycles.

In this equation, S is Cu0 surface area,is chemisorption stoichiometry at monolayer coverage, m is the mass of catalyst, NA is Avogadro constant, V is the total volume of N2O decomposed, Vm is the molar volume, and N is the number of copper metal atoms per unit area of surface (1.47×1019 m-2).
Catalytic activity The dehydrogenation of SBA towards MEK was carried out at atmospheric pressure in a downflow fixed-bed reactor. 1g of the catalyst was charged into the reactor and supported on a quartz grains bed.

Howerver, while Ce3+ doping concentration is too high, Ce3+ and Tb3+ compete in the crystal lattice of the matrix, this leads of the number of Tb3+ luminescence centers reduction and increase of the phosphor luminescence intensity.
Phosphor sample has low luminous intensity as the calcination temperature is relatively low at 600˚C.The reaction gradually complete with calcination temperature increasing, crystals continue to grow thick and crystal's internal crystalline improved, the smaller grain agglomerate into particle.

Analysis of China's food grain problem[J].

Experiment Sample in this experiment is composed of diamond in average grain size of 100μm and concentration 200%, and low temperature vitrified bond (Table1).
Wetting agent number Wetting agent 1 Sodium silicate：Sodium silicate is mixed with water in density of 1.13g/cm³. 2 Phenolic resin solution：Resin was mixed with anhydrous ethanol in mass ratio of 1:1. 3 Dextrin liquid：Dextrin was mixed with water in concentration of 30%.

As a result, the selection of a solid solution of a large number of dispersed carbides on the basis of the alloying components, ie is aging.
The microstructure of the hardened surface of the specimen is a fine-grained martensitic structure with dispersed insoluble inclusions of carbides and nitrides (Figure 2).

The disappearance of primary formed in normal solidification was substitute by a large number of peritectic phases during the solidification of Sn-10 wt.
At higher temperature, peritectic transformation of Sn-30wt. % Cu alloy may be controlled by solid diffusion and also grain boundary diffusion.
