Materials used for the microelectronic devices usually needed the special jointing methods to get special microstructure and physical properties.
During the microelectronic device manufacture, not only the bonding strength between the down-lead and the contact electrode but also the physical properties of devices should be taken into account.
Until now, there were fewer reports about the ultrasonic welding technology of the CZT electrode because many factors would affected the connect strength and electrical properties of the junction interface between the CZT wafer and its electrode.
The pulling test was taken in order to estimate the mechanical properties of the welded points.
The surface treatment of samples was the mechanical polishing.

From the Eq.1 and Eq.2, we can see that the shear stress can be controlled by the magnetic field strength, the properties of SFA and the shearing rate.
Besides the yield stress, field strength and rotating speed, the granularity of abrasives and the processing time are other important factors that may affect the removal rate.
The final surface roughness of work piece may be affected by many factors, but the granularity of abrasives and the type of abrasives, the relative velocity between the work surface of work piece and the abrasive particles in the SFA are very important threes.
Rotating speed of work piece is another important factor that may affect the final surface roughness.
To find out the optimum factors for various materials and figures may be a important task in further aim of our research.

Instruction The high strength of concrete is the main characteristic of high performance concrete, and also high strength generally can reflect better mechanical properties and durability.
Ratio of water to cementitious material is an important factor that affects the strength of concrete when the ratio of water to cementitious material is certain.
To study the influence of the local materials on strength, the cement is acted as one of the studying factors in this paper.
Due to the close chosen level, it is worth noting that the influence of some factors on the evaluation indices is not significant, but the factor itself is not obvious.
-Water-binder ratio is the important factors that affect early strength and 28d strength of C80 concrete strength.

All three factors were significant difference at different levels.
There also has significantly affect between relatively concentration of ROS free radical and properties of board in the process of laccase activated, and more higher concentration of ROS free radical indicated more excellent properties of bamboo particle board [7].
Experiment factors and levels were shown in the Tab 1.
Therefore, increasing the amount of calcium lignosulfonate was good for board properties.
Coefficient of variation of board physical and mechanical properties after six repetitive experimental were less than 8.18%，and this shows the properties of board made by this technology were more stabilize.

The microstructure was studied, mechanical and electrical properties were also analyzed.
Introduction In recent years Cu-Cr-Zr alloys have been widely used in electrical engineering due to their excellent conductivity and mechanical properties [1, 2].
The obtained mechanical properties of the alloy in various states are presented in Table 1.
As shown (Table 1, fig.4), aging of the UMFG alloy leads to a further improvement in mechanical properties.
Summary The effect of a combination of ECAP and classical rolling methods and aging on the microstructure, mechanical and electrical properties of the Cu-Cr-Zr alloy was studied.

The viscoelastic surfactant diverting-acidification technology is a new intelligent matrix acidizing technology.Based on the theoretical analysis，viscosity-variable diverting-acid main agent is selected out.Both the rthogonal design and the grey relational analysis are used to determine synthesis conditions and influence of reaction factors.The production structure is verified by the infrared spectra.Then coreflooding experiments are designed to check the diversion effect,and it shows that the system satisfies the need of diverting-acidification in the carbonate formation.
Mechanical and chemical methods are the mainly diverting technologies[1].Mechanical method enables acid to reach the target rigorously,but it is unable to control the flow of acid within the layer;Chemical method is the most widely used technology,but also has many defects.Compared to conventional diverting technology,Viscoelastic surfactant(VES) viscosity-variable diverting-acid technology has many advantages and becomes the research focus.Based on the theoretical analysis, viscosity-variable diverting-acid main agent and its synthesis conditons are selected out,then multi-coreflooding experiments are carried out to measure its diverting capacity.
The gray relational analysis is based on similar or dissimilarity trends of the factors to measure the association degree between them[5].And it can solve the multiple-factor optimization problems in the synthesis.The steps are as follows: a.Determining the conversion rate as reference sequence xo(k),temperature,time,mass ratio,and catalyst amount as comparative sequence xi(k); b.Reference sequence and comparative sequence data are processed values of the dimensionless by (1) c.Calculating the gray correlation coefficientξi(k) between reference sequence and comparative sequence by (2) d.Connection degrees γi are given by （3） Through the orthogonal design and gray correlation analysis,the best reaction conditions are selected out:(1) amidation reaction:170oC, 6.5 hours, catalyst amount 0.5wt%,the mass ratio between 3-dimethylaminopropylamine

Consequently, the effects of macro-segregation on the mechanical properties of cast Mg-alloys have not been characterized.
It is observed that the inverse macro-segregation of eutectic phase at the cast surfaces adversely affects the fatigue behavior: the fatigue resistance decreases substantially due to the presence of the surface segregation.
Therefore, there must be other microstructural factors responsible for this observed unexpected trend.
The process conditions for plate B specimens intended to decrease the porosity turn out to adversely affect the fatigue properties due to the formation of the macro-segregation on the cast surfaces.
