The characteristics of interface affect the behaviors of a whole structure considerably.
There are many complicated factors influencing the characteristic of the interface.
These principal influential factors include the materials, appearance of contact surfaces, the size of the pre-tightening force, the media between two mating surfaces, the size and geometry shape of interfaces and the characteristics of the dynamic forces of interfaces[1].
Part Ⅲ is the interface region, whose property parameter andcould be available from experimental data and formula (6) and (7).

Samples for mechanical properties test were shown in fig.3 and fig.4.
It can be seen that as the content of mineralized collagen increasing, the mechanical properties of the composite cements overall showed a decrease trend.
Bone cements frequently used in the clinic is polymethyl methacrylate (PMMA),which can not be degraded in vivo, affecting the bone healing.It is a hotspots to develop a biodegradable bone cement to replace PMMA.
produced and in vivo mechanical properties of the composite cement will be investigated in the future.

However, the mechanical properties of the alloy are closely dependent on the coarse second-phase particles (1-10 μm in diameter) [5,6], which derived from the presence of impurity elements, such as Fe, Mn and Si.
Most of the above studies have focused on the effect of the content and size of the Fe-rich phase on the mechanical properties and corrosion performance of the aluminum alloy.
In the following, the microstructure and mechanical properties of the three experimental alloys will be considered to find a more accurate model to describe the fracture toughness of high-strength Al-Zn-Mg-Cu alloys.
The shape factors of the Fe-rich phases, and the deviations of the distributions, are superimposed into Eq. (1) by data fitting.

The calculation values of SIF of the surface crack by FEM had the same properties when the shape and relative depth changed.
The conclusions were as follows: (1) Front side strengthening reduced the stress intensity factors of 3D semi-elliptical surface crack significantly, but the increasing amplitude of strengthening effects decreased gradually with increasing of thickness of CFL
(2) Back side strengthening also reduced the stress intensity factors, but it was not obvious as the front side strengthening.

In conclusion, the distribution, the chemical composition and the amount of the carbides, as well as the matrix microstructure are all factors to influence the crack resistance, hardness and wear resistance of the hardfacing alloys.
Additions of these different alloying elements were to gain good mechanical and wear resistance properties.
All these have further influence on the properties of matrix.

Due to the lack of good mechanical properties of biological materials and synthetic materials, biological compatibility than natural mater The results showed that the three-dimensional porous scaffolds, meniscus of type I collagen can be made into ideal size, shape, fibrocartilage cells attached well in the scaffold pore wall, maintaining stable phenotype, secretion of extracellular matrix.
Type I collagen meniscus scaffold cell compatibility is good, but the mechanical properties of the composite are relatively poor, and other biological materials to improve the mechanical strength, is expected to make an ideal scaffold in meniscus tissue engineering.
The study of tissue engineering meniscus is carried out from the seed cell, scaffold, cell factors, and has gained a stage achievement.
The mechanism of factors on cytokines and regulation is not completely clear.

Steel is the most versatile material and can be made into various forms, types or grades and possesses diverse mechanical properties that made it suitable for different uses.
Thus, in understanding the use of steel, the engineer will need to know how these processes affect the properties of steel.
There are many design factors and these can be found in design books but in the use of steel as design material, the following factors will receive much consideration.

It is necessary to study some basic parameters and factors such as bending stress, contact stress, frictional shearing stress and transmission error to indicate particular gear tooth contact properties [3].
Generally speaking, the researches regarding gear meshing are always focus on the meshing quality, gear tooth strength and relevant safety factors, fatigue, failure, noise and vibration, impact and so on.
The factors which should be considered adequately for eligible research modeling generation are perfect profile, good mesh quality and reasonable boundary conditions.
To acquire the most significant meshing properties responses, the coefficient of friction has been chosen as boundary condition variable due to its obvious nonlinear property, and the variable amounts will be defined as 0/0.1/0.2 in this paper.
The result of frictional stress can also reflect the frictional effects on other characteristic factors, and the particular frictional effects can be explained by the general situation of frictional stress.

The aerostatic guide way is one the structure of the air thrust bearings, the carrying capacity and stiffness are important static properties of aerostatic guide way.
Then analyzed the restrictor structural effect on the static properties of the aerostatic guide way.
It found that orifice diameter and gas chamber diameter have important effect on the static properties of the aerostatic guide way.
Shuliang Ye and Dongsheng Li researched the mechanical properties of the aerostatic guide way with the finite volume method, gained the Pressure distribution of the working plane under different film thickness [2].
So the study of the structure of the restrictor on the static properties of the aerostatic guide way has an important significance.

When choosing the appropriate trenchless technology, several factors need to be considered.
The resin system may or may not contain organic or inorganic fillers and various additives affecting the workability time.
Tests have also shown that non-compliance with design thicknesses has no effect on the mechanical properties of the composite.
It is known from practice that a number of factors influence the resulting thickness of the renovation product.
Other factors that need to be considered are the manipulation of a saturated lining, work pressures during installation, and so on.
