K1 respectively stands for the factors of A, B and C and the first level of effect on the voltage breakdown.
The effect of C factors (the quality of the sodium fluoride) on the voltage breakdown is the largest.
Factors also can be seen from table1 C of the three levels of voltage breakdown of the third level corresponds to the average value maximum, so C factors was picked up third level.

Subsequently, segregation of alloying elements takes place in TWDI casting, which diminishes its mechanical properties [6].
As a result, to overcome problems associated with producing TWDI, understanding of the mensioned factors is vital [11].
It is reported that mechanical properties of TWDI castings, especially strength and ductility, depend directly on graphite roundness; the more roundness of graphite nodules, the higher mechanical properties in TWDI castings [11].
The graphite nodule diameter has a remarkable effect on mechanical properties of TWDI casting [16,17].
As the precipitation of iron carbide in the microstructure severely diminishes the mechanical properties, especially ductility [2,17,18], it is important to produce carbide-free microstructure to make sure the soundness with conjunction to optimum mechanical properties of the TWDI castings.

Further investigations have been performed to study the effect of including material damping and the rate-dependant material properties at different shock loads.
The results indicate that stiffener configurations and shock loads affect greatly the overall performance of steel plates and sensitive to the material data.
As shown in Fig. 3a, at shock factor equal to 0.2 the maximum displacement for model 1 is 99.69 mm.
So, it can be concluded that the damping properties plays a very important role in the response prediction due to underwater shock load.
The effect of stiffener configurations is very important, since it can affect drastically the overall behavior of the plates as indicated.

The geometry of aluminium can affect the surface area of aluminium [7].
One of the factors that can affect the yield of hydrogen production is the dislocation density of the aluminum structure.

The paper analyzes how the grade of wheel and the grinding speed affect Ra surface roughness parameter.
Despite its prevalence in mechanical engineering, creep-feed grinding of titanium-based alloys is still believed to be the most problematic process.
Grinding parameters being altered while the abrasive wheel moves along the workpiece does affect the roughness of the machined surface (Fig. 2).
The abrasive wheel characteristics do not have a significant effect on the general morphology properties.

Domestic and international researches find that: the vital factors affecting the reliability of electrical connectors include temperature, humidity, manufacturing processes, material properties, etc.
Low temperature has the particularly impact on the reliability of electrical connectors: 1) the rubber and plastic become brittle, lose strength and the anti-shock loading capability; 2) the shrinkage of material and the variation of the gap between parts emerges, resulting in the mechanical action fault; 3) the stress corrosion causes the cracking of the contact surface; 4) the changes of the resistance and capacitance affect the performance and reliability of electrical systems, etc [2].
The followings are the fundamental factors concerning the test.
The length of test time not only affects the cost and efficiency, but also affects the authenticity of test results.

Effects of cooling air temperature and cutting velocity on cryogenic machining of 1Cr18Ni9Ti alloy S.M.Yuan1, a, S.Liu1,b and W.D Liu1,c 1School of Mechanical Engineering and Automation, Beihang University, Beijing, 100191, China ayuansm@buaa.edu.cn, bliusiperfect@126.com, cliuweidong_buaa@163.com Keywords: Minimal Quality Lubrication (MQL), Cryogenic machining, Stainless steel, Cooling air temperature, Cutting velocity, Cutting force, Tool wear Abstract This paper presents experimental investigations on influences of cooling air temperature, as well as cutting velocity, on performance in milling of the 1Cr18Ni9Ti alloy with coated cemented carbide inserts.
This may be explained by the mechanical effect of the MQL system, which consists a mixture of cooling air and oil micro droplets.
The function of the cooling air is to flush away the chips from the cutting zone (flushing effect) and reduce the cutting temperature, which are two very important and correlated factors affecting milling of 1Cr18Ni9Ti [6].
It is well known when machining of 1Cr18Ni9Ti, the temperature is very high because of its unfavorable machining properties as mentioned above.
The surface finish can significantly affect the mechanical strength of components when they are subjected to fatigue cycles.

Grinding temperature affects ground workpiece surface quality and cutting characters of the grinding wheel.
Furthermore it will affect the dimensional accuracy and the form accuracy of the workpiece [1].
Conclusions As the discussion above, some conclusions can be drawn as following: 1) The numerical model for grinding of titanium alloy has been developed depending on the transient thermal analysis and the finite element (FE) analyzing method, some main factors for modeling process, including the three kinds of compound boundary conditions, the variable coefficient of convective heat transfer and the different types of heat sources, has been discussed in details. 2) Based on the analysis of the grinding temperature field model, some simulation results are obtained.
