On March, 2007, the Postal Saving Bank of China established, by taking full advantadge of the location and large number of branches, this bank expaned its agricultural business, strived to develop petty loan, and at the same time, gradually searched for rural area fianancial institution wholesale loans and carried out pattern of loans of group of banks to expand the support of agriculture.
In the end of 2008, there are 2000 rural companies acquired the qualification to be listed, however, there were only 59 existed listed agriculture, livestock and aquatic companies, only accounted for 5% of A-shares market, the listed number of stocks only made up 3.74% of A-shares market.
Chinese rural financial market, at present, although the category and amount of formal rural finanical institutions have increased, the trend of rural credit investment is decreasing as the result of the driven of commercial interests that cause rural financial institutions take deposits in the vast rural areas, with the inline tranfered capital and urban branches transferring a large numbers of capital to urban area by credit and loan and stock jobbery.
In the middle the agriculture is the body of rural economy which based on producing grain.

In this work it is shown how mechanical milling has changed the crystallite structure: - of the flake - by mechanical alloying it with 4.5w% copper - if the milled Al(flake)-4.5w% copper have been further milled with nanoceramic particles (10w%Al2O3) For practical purposes in the course of producing bulk materials, the nanostructure of the metal matrix composites (grain size and dislocation structure of the matrix) has to be preserved as much as possible.

When grain size is about 10 nm, the effect of remanence increase is notable, so the magnetic loss can be increased, and it is better to improve absorbing properties.

In an acid aqueous solution of zinc sulfate, it is easy for the formation of fine grained, smooth and compact deposits.
For the latter nuclei growth type that occurred on the graphite composite, two limiting cases can be observed: instantaneous nucleation, where all nuclei are formed immediately after the potential step; and progressive nucleation, where the number of nuclei increases during the whole deposition process [17].
The plot of the columbic efficiency as a function of number of charge-discharge cycles at different current densities is shown in Fig. 4.
And a major change in Qeff with cycling number can be found.

Diagrams of non-uniform compression and concrete tension (a) and the reinforcement deformation with the physical yield point (b): The unknown parameters of concrete deformation diagrams for non-uniform compression and tension (refer with Fig. 2a) are obtained by transforming the original (reference) diagrams using a number of new hypotheses and assumptions [8]: – for the ultimate stage of concrete deformation under non-uniform compression (which corresponds to the cross-sectional area of the compressed element in step exhaustion of its strength at normal section), the fiber deformation passing through the gravity center of the compressive stressing diagram is equal to the concrete ultimate deformation under central compression ebR; – the exhaustion criterion in the carrying capacity of an eccentrically compressed reinforced concrete element is achieved by the fiber grains of this element compressed zone to the ultimate value of the relative deformation ebu with the concrete resistance
Since a number of dependencies in the system is non-linear, their numerical implementation is performed using the iterative methods.
The calculations made it possible to reveal the influence of a number of factors on the bearing capacity of eccentrically compressed reinforced concrete elements: – with an increase in the concrete class calculated, the bearing capacity (Nu) of the samples increases; the greatest growth is observed in the elements where the process of crack formation has received a slight development; in particular, for the samples with an estimated length of 2.0 m, a reinforcement content of 2.0% and a relative eccentricity of 0.45 increase in value Nu turned out to be the greatest and made +47 % and +85 %, respectively, for concrete В40 and В60 compared with В20; with a relative load eccentricity e0/h = 1,0 the corresponding excess load capacity decreased significantly and amounted, respectively, +14 % and +23 %, which is explained by the presence of a more extensive crack zone in such samples; – the raise in the reinforcement ratio of the cross section increases the samples carrying capacity; the
