All of the other effective factors for fabrication of nanocomposite coatings have been fixed for better studying the effect of the ASNP.
However some properties were not studied in details.
These reports are mainly discussed about the changing of average size of particles from several microns to several nanometers which is not expected to be affected from specific properties of nanometric particles.
All of the other effective factors for fabrication of nanocomposite coatings have been fixed for better studying the effect of the ASNP. 2.

Introduction Rock mass in-situ stress field is affected by several factors, among which the effect of the structural plane is quite significant and also quite difficult to precisely evaluate, using numerical method to analyze this problem is necessary and feasible.
Considering the complexity of the mechanical properties of the structural plane, it is generally simplified in numerical model, usually adopting rigid or linear deformation model[3,5], but the linear deformation model could not precisely reflect its actual physical and mechanical properties, several non-linear deformation structural plane have been proposed, among which the Barton-Bandis hyperbolic model is widely used[6,7].
Fig.7 shows the distribution of stress concentration factor of the maximum principal stress in the affected zone.
Actual structural plane deformation is non-linear, deformation stiffness is related to the physical and mechanical properties of the structural plane, and vary with the load, the BB hyperbolic model could well reflect the actual deformation process of the structural plane under load.

Its value is affected by several factors, one of the main was the maintenance of the structure.
The factors that affect the measurement inaccuracy in the control and assessment of concrete strength by non-destructive methods are inhomogeneity of the concrete materials in the sample volume; under-compacted and over-vibrated sections of structure; the disintegration of flow concrete; surface defects; corrosion and carbonation of upper layer.
Thus, the production and technological factors have a rather complex effect on the determination of the average concrete strength and explain the result of any particular test.
Its value is effected by several factors.
At the same time, along with the assessment of physical and mechanical properties of the structure by non-destructive methods, it is necessary to determine the actual concrete strength of control samples made in batching plant laboratory and solidified in permissible humidity conditions.

Finally is the sowing depth, the factors and agronomic seeds, soil fertility, soil humidity etc.
Therefore, air suction type no tillage seeder experimental study in maize stubble to carry out vibration test in this paper, in order to obtain the main factors affecting of vibration and vibration characteristics of the seed metering device in the sowing time, So as to effectively prevent or using vibration improve sowing quality and providing reference of indoor test.
Experimental factors and levels are shown in table 1.
This shows that the main factors affecting the seeding machine vibration is surface conditions, namely the surface roughness is the significant factor causing the vibration seeder, then forward speed.

Furthermore, the cure characteristics, rubber mechanical properties and permanent set were investigated.
The obtained results are found that the ZnO nanograins significantly affected to cure characteristics, rubber mechanical properties and permanent set.
Besides ZnO have many beneficial effects on the mechanical properties of rubber product.
The mechanical properties such as hardness, tensile strength and elongation at break were determined.

The knowledge of the mechanical properties of the material used is a necessary prerequisite for the quality design of any structural unit.
It applies to components manufactured using Rapid Prototyping technology (hereinafter only RP) multiple times, because it is not enough to only know the mechanical properties of a material from which the components are printed.
Other factors affect the component printing, such as the orientation of the printed component, the selection of the component's internal structure, possibility of connection with other materials, etc.
