According to this result, may forecast our country 2012 the soybean import degree of dependency is 58.805%, in the heavy police police region, the front computed result is basic consistent. 3 This article discussed the Chinese soybean market import degree of dependency In this paper, the production status of domestic soybean is analyzed.The reeently change cases such as the unit production, the planting area and the total produetion of domestie soybean, are illustrated and the planting cires change of the soybean indomestic main soybean produce zone is analyzed.On this base, the foreeast model of the BPNN about the total produetion of the soybean is built and the optimization analysis method of the degree of grey assoeiation is used when selecting the number of the hidden nodes of the NN.The status of the supply and demand of domestic soybean is analyzed.The recently change cases such as the supply quantum,the import quantum and the demand quantum, are illustrated associated with

Parallel distributed structure Distributed structure The distribute parallel processing system to distribute structure, we can see, adoption Parallel processing the type imbed the advantage of system processing sketch technique and traditional share total line system like bottom: The structure:The structure of the traditional share total line system has several processing units together and uses one set according to the total line, the address segment taken up by saving machine is same in each number signal processing, while the distribute type Parallel processing the structure of system, each processing unit from independent data saving machine, pass a correspondence to connect with each other.
Characteristics:The traditional share total line system connects structure simple, when the number of the digital signal processor less, can attain high acceleration compare;When handling unit piece is more, sharing the total line will result in multifarious total line conflict and wait for.The distribute type Parallel processing system as long as handle the scale increase, the processing ability of the system become proportion of increment, suit to constitute large-scale Parallel processing system.
Structure parallel algorithm model Based on the embedded system in image processing with the traditional image processing technology compared to have their own characteristics: the parallel algorithm in the image processing of fine-grained, and has a large communication capacity, information content, can be divided into blocks, and distributed and parallel structure have public memory, greatly improves the response time.

Grain boundary is also clear and no corrosion micro-pits on the surface of the polished specimen.
After 10 minutes polishing, the mass percentage and atomic number percentage of Cr increase slightly, but the percentage of other chemical elements almost remains unchanged.
(3) The mass percentage and atomic number percentage of Cr increase slightly

Here Do is the overall desirability value, di is the individual desirability value of ith quality characteristic and n is the total number of responses.

The key point in increasing Jc is improving weak link properties of grain boundary and trapping of magnetic field by non superconducting phase in a superconducting matrix.
Thus doping of CeO2 increases the normal conduction region, the number of flux pinning centers and critical current, however the result indicates deteriorate effect on the magnetic shielding.
The result indicates that ∆M is propotional to the number of magnetic flux lines passing through the sample.

(2) In the freezing engineering, the one that the temperature drops fastest is Quaternary gravel. coarse sandstone keeps the first place when in Cretaceous Stratum, followed by fine-grained sandstone, coal seam is the slowest.

There are a large number of input parameters in the ultrasonic lapping process which will have influences on machining efficiency, machined surface quality, achievable form accuracy.
These process parameters are implemented through reducing tool diameter, abrasive grain size, and vibration amplitude to the microscale.
The reason is that line speeds greater with the Fig.2 MRR comparison plate rotation speed faster lead to the friction intensified and the number of effective abrasive increased .

., reduction of the parameter Ra) was replaced by a rational regulation of complex parameters (Ra, Rz, Rmax, Rvk, Rpk, Rk, tp), which is possible only with the use of a number of processing technologies such as honing or surface plastic deformation or another advanced technology technique [2].
Moreover, quite a number of factors for variations destabilize purely experimentally obtained models, which demonstrates their usefulness in each case, but leads to a need for the recycle experiments changing the input parameters.
In mathematical modeling of the original surface forming process appropriately addressed as a stochastic impact of abrasive grains on a surface of the workpiece [3].

Based on XRD analysis, the powders were examined for their morphology and grain size using a field emission scanning electron microscopy (Model JEOL JSM-7600F, FEI Co., Japan).
However, small peaks of MgNb2O6 or MgNb2O3.67 phase were found, which could be matched with JCPDS file numbers 33-0875 of 25-0525 and became stronger as increasing the calcination temperature to 800℃.
EDX analysis using a 20 nm probe from a large number of particles of calcined powders was listed in Table 1.
