The principles and factors which influence on deburring and some application examples are also described in this paper.
Burrs directly affect the dimensional, shape, position accuracy and surface quality of the workpiece.
Influencing factors of water jet on deburring Burrs have three parameters which are thickness, hardness and shape, the difficulties of deburring mainly depend on the thickness of burrs and hardness[7].
Factors which affect micro-abrasive water jet are complex, could be divided into 5 categories as shown in Figure. 3, every category includes several factors which are listed in square frame, then, these factors which influence on jet are described on the following parts.

Then the frequency of the low frequency oscillation is low, cycle to be longer,and affected area to be wide, it is also big harm to the power system.
Traditional mechanical phase shifter only can classification adjustment, and there are not many classifications.
The kinetic speed is very slow, and its life is short, and it has no ability to restrain the oscillation and improve the dynamic property of the system.

Technical analysis Properties of materials.
CFRP materials have many excellent properties such as better vibration damping performance, higher carbonization temperature, non-toxic, tasteless, non-flammable, good durability.
The study shows that the mechanical properties of carbon fiber were not reduced on the conditions of strong base, freeze-thaw cycle, water immersion, hot and humid environment, it has a good durability.
The characteristic of material properties make FRP reinforcement technology is feasible in theory.
Owing to the effects of smelting, manufacture, construction, use and environmental factors, especially when the steel structure is close to or more than the design life, the steel structure inevitably exist various damage and defects.

It is the discontinuous of geometry or mechanical properties of material that cause stress singularity for the joined junctions or wedges.
Yang and Munz [2] used the similar method analyzed stress intensity factors near the bi-material bonded edge under mechanical and thermal loading.
Munz and Yang [12] solved the stress intensity factors for the bi-material wedges by using finite element method.
Fig.2 Bi- and tri-material junction model Varying material constants As noted above, eigenvalue is affected by material constants too.
All these performances are consistent with mechanical behavior of materials.

Introduction Aluminum oxide (Al2O3), because of its high mechanical properties, good thermal and chemical stability and cost, is widely used as a monolithic ceramic and as a matrix material for composites.
To improve the mechanical properties of ceramic composites, the transformation of dispersed and/or precipitated tetragonal zirconia (t-ZrO2) particles to monoclinic (m-ZrO2) in ceramic matrix is used extensively [1, 2].
In order to improve mechanical properties of ceramics for structural applications, a great deal of attention has recently been concentrated on preparation of layered composites [3].
In the present work, symmetric three-layer Al2O3/t-ZrO2 composites have been fabricated by freeze casting, and their mechanical properties investigated.
The reasons can be explained in terms of two factors.

Introduction Transverse stiffness represents an important aspect of the structural properties of unidirectional fibrous lamina.
Additional problems are encountered when applying these models on metal matrix composites due to the residual stresses that arise during the manufacturing process and affect the stiffness and strength properties of the composites [3,4].
Thus, transverse properties estimated by using such models may deviate considerably from reality.
Micromechanical Finite Element Models (FEM) were used to accurately predict the transverse properties of continuously reinforced fiber composites.

A study conducted by [ 2 ] indicated that the type of mower used can affect turfgrass quality.
Cutting and grass cutting has many variables that have an impact on crushing and some of the important variables are the cutting speed and the percentage of moisture from the vine, and there is a need to establish a model of cutting mechanics and to relate knife parameters to forage material properties [ 3-6 ].
Chattopadhyay and Pandey [ 9 ] stated that flail-type cutting devices require a minimum knife speed for effective cutting.There are requirements for additional cutting mechanics and for further studies of the cutting action of knives and therefore there is a need to create a model of cutting mechanics and to relate knife parameters to forage material properties [ 10 , 11 ].

These factors give an estimated idea of thermal heterogeneity impact on the cenospheres formation in flue ashes.
However there are of interest the factors influencing heat conductivity of the cenospheres layer.
This result, in our opinion, can be explained by such factors as distinction in cenospheres sizes and distinction of their chemical composition.

In this work, the variation of comprehensive mechanical properties of F550 ship steel was researched through comparing with lamellatizing-tempering and complete quenching and tempering, and the influence mechanism of different heat treatment processes on microstructure and properties of experimental steels was analyzed from microscopic viewpoint, and the optimum technological process was explored.
When the temperature is close to Ac1, much lump shaped ferrite is generated in the matrix, which lead to the decrease of mechanical properties of the steel.
