In addition, mechanical, physical, and chemical properties of molybdenum nitrides are typically important for wear resistance, crack resistance, and corrosion resistance [4].
Srisattayakul et al. (2014) studied three coating factors affecting the elastic modulus of the MoN coating on upper hooks [6].
They found that DC current, operating pressure, and Ar/N2 ratio were statistically significant and the treatment combination of the DC current of 0.35 A, operating pressure of 0.01 mbar, and Ar/N2 ratio of 1.5 was the optimal operating condition of the coating factors affecting the elastic modulus.
Since the interaction effect between the factors of operating pressure and Ar/N2 was higher than the other two interaction effects (see Table 2), the interaction effect plot between the two factors (i.e., operating pressure and Ar/N2) was used to determine the optimal operating condition of the significant factors.
The DC current, operating pressure and Ar/N2 ratio were found to be statistically significant sputtering factors.

The paper introduces the working principle of the system and analyzes the factors that affect the accurate measurement.
By considering the flow resistance, material properties, manufacturing difficulties and other factors, the optimum cross-sectional shapes of a single probe tube was identified as the circular.
In addition, factors affecting the flow coefficient should be considered, for example, Reynolds number, fluid expansion correction factor, thermal expansion coefficient of the measuring device, the flow area ratio.
The performance test The establishment of an aerodynamic testing system.To further study the properties of measuring devices, an open air-solid two-phase test system is building.
When the angle is less than is less than 6°, the error is less than 1%. 5, Structures and properties of the average pressure chamber and the gravity pendulum, etc. are scientific and reasonable , anti-purging system is working properly.

Generally, material with high mechanical properties exhibits low damping capacity and vice versa.
The material properties foreach type of material are shown in Table 2.
The mechanical properties assessed in this experiment are mainly damping capacity, yield strength and ultimate tensile strength (UTS) of the materials.
The high damping capacity is observed in materials exhibiting poor mechanical properties, for instance yield stress or hardness.
From Table 2, it is observed that the mechanical properties of mild steel are higher than aluminum alloy.

Structure controlling of wrought magnesium alloys Alloy phases.The geometry, size, amount and distribution of alloy phases have obvious effects on the plastic forming property of wrought magnesium alloys, which are also important factors to determine alloying structure, mechanical properties and corrosion resistance.
Zhang and co-workers [4] investigated the effect of Rare Earth Ce on grain size and as-cast mechanical properties of AZ31 alloy, the results showed that the grain size decreased with the increase of Ce content, and the mechanical properties were improved evidently when the Ce addition was less than 1%.
The effects of Ce addition on the microstructure and mechanical properties of AZ61 alloys had been investigated by Zhou et a l[5].
Plastic processing technology.In the past years, the investigations on the plastic deformation process have been focused mainly on the optimization of process parameters and effects of technological factors on structures and properties of the AZ31 wrought magnesium alloys.
Song et al [24] investigated the YAG laser welding process of AZ31B alloy, and indicated that the pulse width was the main parameter affecting properties of the joint.

(1) The building deformation caused by excavation with the size of the stiffness of building, ground deformation amount, ground properties etc related.
But when the ground subsidence was larger, shallow water table diving rise, would make the buildings with water for a long time, or in wet environments, thus affecting the use of the buildings [7].
The buildings would be affected for the ground curvature.
The buildings would be affected for the torsion.
It were analyzed that the regularity of the influence of foundation pit excavation on buildings in this paper, it was found the ground foundation subsidence, tilt, curvature, torsion and other factors may lead to building cracks, inclination, or even collapse through the survey.
