The yield stress of steel C4D was taken from the material database of Forge2011® program and entered onto computer simulation in the form of a function described by the Hansel-Spittel Equation 1 [9, 10, 11, 7].
It is assumed that regarding this model, under abrasive wear conditions, Vz of the material separated from the tool surface of the unit is directly proportional to normal stress, sn, acting on the tool surface and to the friction path, Lt, and inversely proportional to the hardness H of the material undergoing wear (in this case, tool hardness).

In this respect, polyoxometalates (POMs), with versatile structural diversity and unleashing exciting new properties such as high negative charge, represent a widely used inorganic building blocks, have been widely exploited for the construction of organic-inorganic hybrid materials [8-12].
On the other hand, owing to the interesting catalytic, bioinorganic and physical properties (such as mimic functional biological systems and single-molecule magnets (SMMs)), Schiff base and its metal complexes have been extensively used as excellent subunit for the construction of hybird-type materials [13-17].
Given that few works combined POM with metal Schiff base, systematic synthesis of new hybrid materials with these two libraries of interesting and reliable molecular nanostructures remains a pressing challenge [18-21].
Our research, to some extent, provides a new path for the design and synthesis of hybrid materials between metal-Schiff base complexes and simple inorganic salts.

Material and Method: Eighteen adult Sprague-Dawley rats were used.
The fabrication methods used to construct the conduit should be cost-effective, simple, and easily applied to a wide variety of materials.
Various materials such as nerve growth factors, platelet degradation products, stem cells may be used to fill the conduit and see if it facilitates the regeneration of nerve in future studies.

Firstly ，providing material source for slope failures of the loess.Secondly， the tectonic structural surface（bedding plane,fault plane,joint plane,unconformity plane etc）controls the loess slope slide surface ‘s spatial location and distribution for the slope of the time and space.Thirdly ,determining the groundwater’s distribution and movement law of the the loess slope. 2） Geographic and geomorphic Loess geomorphy is common molded by the quaternary wind-blown loess,tectonics and soil erosion，whose grown forms are loess source,girder ,mortise and also deep valleys among them.
Therefore, the additional stress of the earthquake effect,have much impact on the stability of the slope . 4）The factor of human Human engineering, economic activity is the important factor on triggered loess slope instability .According to the survey,there are 80% of the loess slope failure in Guanzhong area caused by human activity.Human engineering, economic activities, including irrigation, and road construction, building materials digging and living and filling with soil, spoil, building loads and so on. Ⅴ The Investigate on the Mechanism of loess slope instability A Changes in soil structure and soil structure model Loess structure and sequence structure clearly with a level of sequence.The structure of the loess loosely,Pore Development,Vertical joints;particle separation well,the main contact with cement;loess is a kind of soil that mainly Composition by Smectite,, kaolinite clay mineral,with good hydration soften,A significant reduction in shear strength of the hydration
