Different factors and their influence on electrocatalytic activity, have been discussed.
The presence of a solvent on the surface of the electrode radically changes the properties of the surface and has influence on the kinetics and the mechanism of the occuring electrode reactions.
Recent advances in electrocatalysis and interfacial electrochemistry show that these fields are rapidly expanding disciplines strongly affecting on other areas of physical sciences, and heterogeneous electrocatalysis is a core field of interfacial science [2,10].
Catalytic activity of the electrode materials in electrochemical reactions is generally related to their chemical and physical properties.
A great interest is observed in nanostructured materials, especially in nanoparticles, due to their functional properties which are generally different from those of the bulk materials.

In generally, the areas affected by the foundation pit excavated depend on the plane shape, the depth and soil of the foundation pit and other factors.
In this numerical simulation the foundation pit of width is 30m and depth is 21m, and affected areas is 1.6 times the size of the foundation pit as shown in Figure 3.
Parameters in Computing By physico-mechanical properties of soil obtained from the Geotechnical engineering investigation report and some of the similar nature of the soil combined, all soil are divided into five categories, whose mechanical and physical parameters are shown in Table 1.
And many other factors cause that, such as in the actual construction process, there is some phenomenon of overbreaking of foundation pit, occasionally dynamic load affects to foundation pit by the construction vehicles passing through and so on.
The effective exertion of steel support is restricted by numerous factors, in which the different rock-soil deformation is one of the reasons that greatly decrease the supporting effect of steel support.

The mechanical properties are investigated by means of two tests: tear strength and sequenced tensile tests, which are able to characterize elasticity and elongation at break.
Mechanical properties.
SEBS formulations have been mechanically tested; mechanical properties have been represented as a function of the weight percentage of nano-particles for each kind of nano-particles.
The mechanical properties have been investigated with two mechanical tests: a tear strength test and a sequenced tensile test.
The incorporation of nanoparticles in SEBS can lead to the improvement of some of the mechanical properties such as tear strength, elongation at break and stress flow.

The material properties of the laminates are shown in Table 1.

A new nozzle was fabricated based on nozzle die angle which was one of the factors that can affect the stability of the extrusion process.
Every material possessed different properties which required different nozzle die angle [6–8].
All these factors was investigated to determine their impacts on the extrusion process [6–9].
These factors contribute to a significant impact on the finished parts as the new nozzle is better in terms of dimensional accuracy compared to the original nozzle.
Evaluation of dimensional accuracy and material properties of the MakerBot 3D desktop printer.

This negative factor has highly affected the reliability of water wall heating surfaces and led to the need for frequent boiler shutdowns and mechanical cleaning of furnace chamber water walls.
Turbulent gas properties are calculated by use of a two-parameter «k-e» – turbulence model which also takes into account the effect of moving particles.
Such aerodynamic structure positively affects completeness of burning fuel particles in up flow and reliability of subsequent heating surfaces.
Such negative factors of Talovsky coal combustion as undersize of fuel particles and lower surface contact of the aerodynamic lug with the combustion core can be attributed to shortcomings of the selected layout relevant to a specific combustion chamber.

The earthquake affected 27 villages and towns of 7 counties in Qinghai and Sichuan Province, affecting 35,862 square kilometers of land as well as killing 246842 people.
After the earthquake, plenty of examples show that the roof is overweight, which is the main factor causing houses collapsed.
Frost volume expansion destroys the wall and reduces soil adhesion between grip strength and influences the mechanical properties of the wall. 2.
Discussion Due to that the different soil properties and different materials, the response to the variation of different soil properties should be understood, so as to take the most appropriate construction technology.
Rammed earth construction relates to the determination and arrangement of load-bearing structure, which can be improved from the following aspects: 1.From the point of view of seismic design for rammed earth quality, through the correct operation of construction technology and reasonable use of unification, the specialized technical staff should be responsible for implementation. 2.In the forming process of rammed earth materials, construction technology, stirring, water, solid work and other factors influence the strength of rammed earth.

In this experimental plan three factors have been proposed, the answer find is the behavior of the recycled asphalt to fatigue and the influence of factors study on the response for each formula also the compatibility of binders with the performance wish.
These results have confirmed the classic tests performed where we have seen that the rate of aggregate of asphalt contains a percentage of the old binder which affects the mechanical performance of recycled asphalt.
The modeling allows you to determine equation (1) by which one can estimate the fatigue for different rates of the factors studied. 6.

But the sensitive resistance was affected by many factors, including interface properties of carbon fiber and cement matrix contact,which is the bridge of information transmission.
It will directly affect the performance of carbon fiber reinforced cement based composites [1-3].

However, the conventional epoxy resins do not posses adequate thermal and mechanical properties to meet the requirements of high performance structural products [3, 6, 7].
