Hence, it becomes necessary to comprehend acutely the effects of such manufacturing processes on the material properties, such as the crystalline quality of the transferred layer or its electrical and optical properties.
In this extent, SiC-on-Insulator (SiCOI) structures can be of great interest for probing the properties of the transferred layer alone, electrically insulated from the receiver substrate.
Using such, it is possible to measure the electrical properties of the transferred layer, affected by the ion implantation step [14], before the recovery of the material in the finishing steps.
For this reason, we chose here to use the SiCOI structure as a tool for characterizing the electrical properties of the transferred SiC layer.
We considered a Hall factor equal to 1 – close to the values previously measured by Rutsch et al. [21] under similar magnetic field.

Through many experiments and field practice, the author found that the bearing capacity of the anchoring section of anchor cable is not only effected by the bonding stress along the anchoring section, but also effected by many other factors, which can be expressed in expression (2): (2) Where is the load bore by the part of anchoring section; is the contribution coefficient loaded on the part from the anterior and posterior segment of anchoring section; is the borehole area of the part; is the length of the part; is the properties of the cement mortar of the part; is the properties of the stratum around the part; is grouting pressure loaded on the part; is the properties of reinforcement material.
Fully considering soil and rock self stability and the interaction among environmental factors and engineering are the new thought for slope anchorage Engineering.
(2) The anti-corrosion technology mainly points to the external and internal factors that can induce anchorage structure corrosion.
So studies on slope anchoring mechanism are still need to strengthened, including the study of anchorage system effect on the stress distribution and mechanical properties of rock and soil and the working performance of anchorage system under the effect of earthquake or blasting impact load.

The regenerative type is found to be the main limiting factor to the production rate in most machining processes Fig. 1 [3].
Frictional properties of the tool work piece interaction affect the dynamic cutting force characteristics and, consequently, have a great influence on the process stability.
SDOF modeling of the turning process including tool wear Two approaches are possible to extend this work to multi DoF systems, one is to find the dominant mode of a mDoF system and use its parameters as the equivalent properties of the sDoF system.

The slope analysis is a mechanics process for geological body, which has property of discontinuity, including interdependent elements and easily influenced by seism.
The high arc dam system of hydraulic engineering has above complex factors of slope.
Affects for the latent sliding face in the infinitesimal body's normal average compressed stress.
Conclusion Rock mass fracture and crack and the seismic environment are unavoidable factors of high arc dam system influence the sliding safety of dam shoulder slope.
The developed model including dynamic contact element reflecting local rock crack and quasi continuous medium reflecting large deform can accurately simulate above factors.
