Assessment indicators, determine the impact of factors and factor levels To be considered from the point of view of structural design and material design, the asphalt layer thickness, base thickness, the modulus of the asphalt layer, base modulus and subgrade modulus are the main factors affecting the assessment indicators.
The range is greater, the description of the factors that affect greater.
Therefore, analysis of variance, and further analysis of the fluctuations of the influencing factors affect the extent of the indexes.
Sensitivity analysis Through the intuitive analysis and variability analysis above, we can get the impact of factors that affect the degree of control indicators[5].
Summary The sensitivity analysis shows that the importance of factors affect pavement design indicators are not the same.

Research of Single-crystal Diamond Abrasive Efficiency Raising abrasive efficiency is the key of reducing the cost of single-crystal diamond abrading, and many factors affect abrasive efficiency, which will be discussed below.
When we design single-crystal diamond tools and determine which crystal face can be taken as the face of tool or flank of tool, some factors should be considered: a.
The crystal face should have high hardness, good wear property and low friction factor with workpiece; b.
But [100] crystal face has better wear property and smaller friction factor with nonferrous metal and higher micro-strength, it is easier to obtain a shaper cutting edge by abrading [100] crystal face then [110] crystal face.
In addition, following special factors should be considered: a.

Existing research on machined surface topography, only consider its response to vibration or wear certain factors, both vibration and wear impact on machined surface topography exist ambiguity and uncertainty, it cannot solve the design conflicts of machined surface topography.
Present study on machined surface topography[2,3], only consider tool vibration or wear certain factor affecting machined surface topography[4], found that amplitude is the most sensitive factor affects surface residual height[5], with blade wear contour become not clear gradually, surface residual height increases[6,7], face milling process is chip breaking cutting, cutting process is accompanied by vibration and wear, machined surface topography is characterized by the behavior of cutting tool on machined surface mapping, considering the influence of machined surface topography under the two sides jointly will have important significance.
From geometry of machined surface topography to start, consider installation error, tool vibration, wear and deformation impact on its features to build a three-dimensional machined surface topography simulation model[8], extract its characteristic parameters, using gray system theory to analyze experimental data obtained from milling experiment[9], focus on solving the interaction between various factors, access to primary and secondary order of various factors.

By the uniqueness theorem of limit,both the theoretical formulae of stress intensity factors and analytic solutions of stress field and displacement field near interface crack tip are deduced.
In addition, the stress intensity factors, stresses and displacements of interfacial crack tip for each material are together affected by two bimaterial elastic constants.
