Among them, the electrode material is the most important factor.
Carbon/ conductive polymer Material The conductive polymer is a kind of conductive polymer, its mechanical properties are poor, easy to aging and fall off, so it need to be attached to a certain skeleton to play the advantages of its pseudo capacitor.

They are also attractive in application to the aircraft and automobile parts for increasing the fuel efficiency and the transportation speed; however, their poor mechanical properties, especially, their low high temperature strength hinder the wide application of magnesium alloys.
The size factor of aluminum in magnesium lsf(Al/Mg) is -13.73% [[] H.
This value does not have large difference with the size factor of yttrium in magnesium lsf(Y/Mg) roughly estimated by XRD analysis of Mg-Y solid solution alloys in absolute value (+11%).
Zinc has little effect for changing stacking fault energy, but an attractive interaction occurs between zinc and yttrium atoms in hcp magnesium lattice because the values of their size factor in magnesium are negative and positive, respectively (lsf(Zn/Mg) = -20.00% [13], lsf(Y/Mg) = +11%).
However, the activation of a-dislocations are predominantly in most of the grains, thereby the cross-slip and/or prismatic slip affects creep rate in the Mg-Y and Mg-Y-Zn based alloy as the rate-controlling mechanism at the temperature range from 480 to 570 K.

Hence, it becomes necessary to comprehend acutely the effects of such manufacturing processes on the material properties, such as the crystalline quality of the transferred layer or its electrical and optical properties.
In this extent, SiC-on-Insulator (SiCOI) structures can be of great interest for probing the properties of the transferred layer alone, electrically insulated from the receiver substrate.
Using such, it is possible to measure the electrical properties of the transferred layer, affected by the ion implantation step [14], before the recovery of the material in the finishing steps.
For this reason, we chose here to use the SiCOI structure as a tool for characterizing the electrical properties of the transferred SiC layer.
We considered a Hall factor equal to 1 – close to the values previously measured by Rutsch et al. [21] under similar magnetic field.

The properties are ensured by aluminizing the steel, i.e. applying a layer of aluminum of the required thickness to its surface.
Another factor influencing the properties of the diffusion zone is the use of alloying elements.
It should negatively affect the adhesion strength values.

This reaction can be influenced by several factors, such as the soil properties, pH and temperature.
This mixture results in a material with properties similar to the Portland cement.
However, in other properties this addition is not always beneficial, sometimes occurring a decrease on mechanical strengths.
This viscosity control is important, once it has influence on the amount of water used and on the mechanical properties [21].

Through many experiments and field practice, the author found that the bearing capacity of the anchoring section of anchor cable is not only effected by the bonding stress along the anchoring section, but also effected by many other factors, which can be expressed in expression (2):
(2)
Where is the load bore by the part of anchoring section; is the contribution coefficient loaded on the part from the anterior and posterior segment of anchoring section; is the borehole area of the part; is the length of the part; is the properties of the cement mortar of the part; is the properties of the stratum around the part; is grouting pressure loaded on the part; is the properties of reinforcement material.
Fully considering soil and rock self stability and the interaction among environmental factors and engineering are the new thought for slope anchorage Engineering.
(2) The anti-corrosion technology mainly points to the external and internal factors that can induce anchorage structure corrosion.
So studies on slope anchoring mechanism are still need to strengthened, including the study of anchorage system effect on the stress distribution and mechanical properties of rock and soil and the working performance of anchorage system under the effect of earthquake or blasting impact load.
Analysis of factors influencing the stress distribution in prestressed cables[J].

Abstract.
Although, the mechanical stresses experienced by the TP are within acceptable limits compared to other parts, high temperatures and large temperature gradients affect the structural integrity of these components, which makes TP a very critical component of a gas turbine in structural and thermal designs.
Assumption of the solid wall of the quarter torus is formed with a hypothesis of negligible thermal resistance by conduction, the thermal properties of the material were considered by Nimonic 263.
The convergence criteria of the steady-state solution are judged by the reduction in the mass residual by a factor of 6, typically, in 2000 iterations.

Moreover, it must exhibit sufficient mechanical strength to provide structural support during bone
growth and remodeling.
The microcracks should not affect (positively of negatively) the biological performance of scaffolds but they certainly reduce scaffold's mechanical properties.
Another important factor related to the quality of the produced scaffolds with regard to their potential in biomedicine is the size of the pores as well as their interconnectivity.

This paper is composed of three main parts:
First, some aspects concerning the material properties are briefly discussed.
Components for these applications have precise requirements on mechanical and physical properties [9].
The chemical composition and the key physical and mechanical properties of Ti-6AL-4V are listed in Table 1 and plotted in Fig. 1.
Such evidence justifies the assumption to neglected phase transformation model in the material thermal, mechanical and physical properties in both the software.

The existence of boundary can influence the mechanics, physical properties and chemical properties strongly.
The interface atomic motion time parametercan affect the speed of the liquid atoms around adding to the interface as well as the growth velocity of dendrite.
(2) Here,,,,are the interface width, relaxation time, thermal diffusion coefficient and coupling factor, respectively.
Parameter d0 and model parameter D can be linked together by asymptotic analysis method. d0 and D should be based on the properties of materials, here we choose d0 and D in this paper for simplicity, and change the coupling coefficient by changing the thermal diffusion coefficient.
