The soil is simplified to 3 layers, and used Mohr-Coulomb material model, the specific parameters of each layer soil is shown in Table 2.
Simulation Results and Analysis In the ADINA simulation, at first, selecting the same materials, the same number of anchor ropes, the same time of playing anchor ropes, the same excavation steps, the different length of anchor ropes to simulate, it will get the displacement of the pile tip and the pile packing, and in order to find the law, it will be merged into a displacement curve, the result is shown in Figure 2.
In the case of the same materials, the same number of anchor ropes, the same length of anchor ropes, and the same excavation steps, the different time of playing anchor ropes, it is simulated, and the result is shown in Figure 4.

Introduction Mineral resources, which offer a large number of mineral raw materials and energy materials, is one of the indispensable basic of human society.
Application of Wasteless Mining Hongtoushan Copper Mine with a history of 50 years vigorously develop comprehensive technology research of energy saving and emission reduction for deep mining, supported by national science and technology support project, to responded the appeal of the country.
Using the waste rock as filling materials can improve the quality of the filling body.
Meanwhile, it solve the shortage of filling materials and reduce the cost of the mine.

These sample present higher hardness and lower wear coefficient if compared with other orientations Introduction Silver presents the highest reflectance in the visible light spectra (97,7% at λ= 500 nm) and the lowest resistivity (1,6 µΩ.cm-1) among the metallic materials.
For fcc materials, such as Ag, the highest density and adhesion is achieved with the (111) preferential orientation.

In the method of non-traditional machining, metal materials are cut by energy such as the electrochemical energy, light, sound and heat, and etc instead of mechanical energy.
Because the core of the RP technology is the process of the material piled, the property of the material has a decisive significance for the RP technology, the material powder with appropriate ratio is the key of the process.
So the RP technology should be developed accompany with the material science [9].

For this reason, a lot of encapsulant materials have been investigated in order to find an optimal design for a desired release system.
Hydrogel is a widely employed soft-material-based encapsulant which controls the release kinetics of encapsulated ingredients by controlling their mass transfer resistance through the polymeric network.
One of the biggest advantages of cryogelation is that the process employs low temperature highly suitable for encapsulating heat sensitive materials such as proteins and enzymes.

The flesh of mulberry is excellent raw materials to brew fruit wine because of that it is more juice in fresh, bright in color, quiet and tastefully laid out in aroma, high content and stable in pigment.
Material and Method Material.
The sugar provides energy for the growth of yeast and provides the raw materials of metabolism to produce alcohol, so that change of the sugar concentration plays a key role in the fermentation process.
Under these conditions, the wine alcohol is 10.3v/v, which is sufficiently improved the utilization of raw materials of mulberry and the economic efficiency.

The ablated material is then deposited on the substrate kept 50mm away from the target.
In spite of the same material, when the crystal axis direction of the substrate is different, the obtained values are not same.

Introduction In planarization CMP (Chemical Mechanical Polishing), extra materials on the work surface are removed by the combined actions between the chemical reactions of the chemical ingredients in slurry and the mechanical actions of the polishing pad and abrasives.
The goal of this study is to develop the next generation CMP technology to simultaneously planarize both sides of the hard-to-process crystal materials such as silicon carbide (SiC), sapphire and gallium nitride (GaN) to a high quality surface by controlling processing atmosphere.
Summary We focus attention on the processing atmosphere surrounding workpiece and design the prototype of a simultaneous, double-side CMP machine with sealed and pressure container as a series of our research on the high-efficiency and high-quality planarization of hard-to-process materials.
The research will be continued and followed by the new planarization study of hard-to-process materials under the oxygen gas atmospheres assisted with generating active oxygen by photo catalytic reactions.
