Introduction To produce soybean protein concentrate or in the process of soybean protein isolated produces a large number of soy whey liquid, contain soy whey protein, soy oligosaccharides, soybean isoflavone, soy saponins from many physiological activity material composition.
Soybean oligosaccharides were soybean grain the floorboard of the soluble sugar, main component is water stachyose, raffinose and sucrose [1].
Soybean oligosaccharides refining process were studied by the numbers.

Repetitive contact tests were performed on the ATM composites and coated layered structure with the same spheres using the same tester, for number of cycles n = 100 at the crosshead speed of 0.06 mm/min and loads up to P = 30 N.
The result is based on the densification of composites and the suppression of grain growth in Al2TiO5 grains by the addition of mullite [2].
We introduced the same number of contacts on ATM monolith and the glass-coated ATM composites.

We collate the knowledge and experience of the experts and accident cases ,assign a unique number for each accident case (knowledge) and create a subsystems - component - the fault phenomenon tree form index based on the knowledge name and the number of the knowledge which is stored in the management Agent’s knowledge base.
We adopt a combination of functional decomposition, structure decomposition and faults decomposition based on the structural characteristics of excavators and the complexity of the failure, by using the function, structure decomposition method in the upper part of the task tree (on the coarse-grained), and using faults decomposition the next half of the (fine-grained) to establish a clear diagnosis of the task hierarchy tree.

There are a number of issues exist in supply chains: ·Experience over the timetable for changes in the sub-tier suppliers ·A similar capacity bottlenecks have more than one supplier ·Inventory or WIP levels often deviates the expected Many supply chain issues is actually a system problem.
Small-grained, agent-based systems offer a promising alternative to the monolithic software modules being developed today.
A small-grained agent is a simple agent that responds to its environment using simple rules or interacts directly with other agents through Booking Agreement.
However, these changes will not change some of the functions, and some numbers will not change the cross-handling of materials.

Fig.6 The acceleration of the electric spindle in running state (a) The spectral distribution in X axis (b) The spectral distribution in Y axis (c) The spectral distribution in Z axis Fig.7 The spectral distribution in three axes in the initial processing stage Finally, based on the analysis of the number of vibration grain on the parts, it is found that inducing vibration frequency should be 300 Hz.
Because a circle vibrating grain number of the work-piece is 64 ~ 65, the inducing vibration frequency of the work-piece is ftf= ft×64~65=298.88~303.55(Hz), which is consistent with the result of the spectrum analysis.

Because they are mostly formed by ionic bonds and / or covalent bonds, which provide a limited number of independent slip systems necessary to achieve a homogeneous plastic deformation.

The samples have a homogenous microstructure gradually with good grain size distribution.
The sample number 3 was used because showed satisfactory results in previous tests.

The more the number of crystalline particle, the more the number of carbon atoms at grain boundary which were more than micron diamond film and most of them were sp2 phase.
When the substrate temperature was lower, the number of point defects and activated groups become fewer.
With the decrease of pressure, the recombination free path of hydrogen atoms and activated groups would increase accordingly, the inelastic collision probability and the energy lose would decrease, the number and energy of activated groups which arrived at substrate surface increased greatly, the collision effect between the particles and the substrate surface and the activity of the absorpt particles were enhanced, the carbon bunch could be formed quickly on the surface and the secondary nucleation rate would be improved finally.When the pressure was higher, it was against diamond film of nucleation and growth from the a line in Fig.2.
The main reasons were the decrease of free path of hydrogen atoms and activated groups, and the increase of the number and energy of activated groups for many times inelastic collisions before the groups arrived at the substrate surface.

In this way, saturation within a certain range, accordingly the growth rate of particles are controled, and finally fine powders with uniform grain size are obtained.
By colony-counting method [2,3], the antibacterial properties of ceramics are evaluated about changes in the bacterial numbers by means of comparing the test samples with the contrast groups.

When Ag2WO4 on the glaze layer reaches saturation, the number of dissolved ions will not change with increasing powders gradually, and the antibacterial effects will not as well.
Conclusions Fine Ag2WO4 antibacterial agents, which are prepared by supersonic assisted homogeneous precipitation method for 45 minutes, at 40 oC, can achieve the best antibacterial activities, and grain size, uniformity and antibacterial properties of powder are better, compared to chemical synthesis method.
