The dynamic properties are influenced by structure parameters and the performances of controller.
Therefore, the select factors are KMv, TMe, Dp, AC and.
Factors and their levels are shown in Table 2.

Therefore, the order of the five factors is.

The micropores will cause blister defects in solution treatment, which prevents from improvement of the casting mechanical properties with the treatment[1-3].
To avoid the micropores resulted from the gas entrapment and fabricate die castings with high mechanical properties using solution treatment, some new methods about die casting processes have been proposed and developed recently.
Lu[7] et al reported that the impact property of Al-Si gravity casting is practically affected upon dendrite cell size.
Furthermore, effect of microstructure factors on impact property was discussed as well.

In order to try to reduce the influence of weld mark on the appearance quality and mechanical properties of plastic products, with the combination of injection molding simulation software and the orthogonal test design, reasonable test analysis programs was designed.
The existences of weld mark not only affect the appearance quality of plastic parts, but also reduce the strength in the welding place of plastic parts.
Material properties of products (such as plastic melt liquidity, etc.), injection molding process parameters (including injection rate, holding pressure, melt temperature, mold cavity temperature, etc.), the mold structure (such as gate location, gate number, etc.) and plastic parts structure (such as the presence of holes, wall thickness is not equal, etc.), are the main mechanism and factors that produce weld mark [2].
Through the statistics and analysis of the test data, the degree of influence on the evaluation of the test factors can be concluded.
Holding pressure (A/%), injection rate (B/cm3×s-1), melt temperature (C/℃) and cavity temperature (D/℃) are selected as the test factors, and each factor sets three influence levels, the factors and their levels as shown in Table1, the holding pressure is controlled by the percentage of filling pressure.

Adhesion strength is provided by a number of other factors, including the diffusion of the coating components into the base material, fusion and chemical compound.
However, pretreatment of the base surfaces remains an important factor for ensuring the adhesion strength of the applied coating with the part, since in most cases, the connection of the sprayed coating with the basis occurs as a result of mechanical clutch.
The use of thermomechanical treatment of preformed coatings (applied by gas-thermal spraying) makes it possible to increase the adhesion strength of the coatings with the base while preserving the original structure and properties of the powder as much as possible [16].
Theoretical Part Analysis, justification and development of recommendations on the use of methods for testing mechanical properties of materials, including composite ones, obtained by methods of gas-flame spraying of coatings, is one of the most important stages of the study, which allows not only objectively judging the mechanical behavior of parts during operation, but also actively to manage the resource of their work, affecting the composition, structure, properties and technology for producing coatings.
The adhesion strength of coatings with the base metal is one of the important factors characterizing the possibility of using metallic coatings.

This is the normal solidification sequence and causes a serious deleterious effect on certain mechanical properties of the weld.
Thus, a refined equiaxed structure is most desirable in fusion-welded materials in promoting good mechanical properties [16].
The more the colonies of small sized equiaxed grains the better the mechanical properties of the weld.
However, this work did not assess the mechanical properties of the weld in relation to those of the base steel.
The pulsed AC weld, however, exhibited better mechanical properties.

The main factors affecting the movement and deformation of the surface (1)Ratio of mining depth and mining thickness Different mining seam thickness, resulting in subsidence gob collapse of overlying strata with different crack height, with a high degree of surface collapse crack forms and degrees of movement and deformation damage plays a decisive role
(2)Mining methods and roof management methods Mined subsidence processing methods are mainly based on the top floor and the mechanical properties of rock layers composition, thickness coal seam, the special requirements of the ground (rivers, railways, buildings under mining) and other factors to select [2]
Depending on the different risk factors that impact on the natural gas pipeline, and now scores of the factors given in Table 1-2 were mining methods, ratio of mining depth and thickness, overlying lithology, subsidence gob formation time, the level of distortion , tilt effect radius, and the sinking value of the mined subsidence type score.
Inflection point offset d = 0.05H, subsidence coefficient =0.8, mainly affecting the tangent tgβ = 2.0, horizontal movement coefficient b = 0.25[7].
(2) Using AHP to the previous analysis of influencing factors evaluation, building subsidence gob gas pipeline risk assessment system

Therefore, the rapid drawdown of the water level induced landslides many factors, matric suction against the influence of shear strength is an important control factor.
Dongmei Sun pointed out that the matric suction in addition to affect the shear strength, the slope body cause of unsaturated flow and capillary water saturated zone can also affect the security analysis of the final results.
The change rule and the influence factors of stability of slope in the process of rapid drawdown of water table .
And the change of the soil parameters, the initial water level such factors on the slope safety would cause a great influence, in the future research is necessary for these parameters for further analysis.
But the conventional geological mechanical model test is limited by the model size, causes similar material mechanical properties is difficult to satisfy the similar ratio, and at the same time, size effect also make the model test results reliability is affected certainly.

The numerical stimulation results showed that above three factors significantly affected the power generation output and generation stability.
Thus, the optimization of the three factors was achieved in this paper, which provides the basis for the solar chimney heat storage system design.
Based on the law of conservation of energy and the system heat transfer flow mechanism, Mullett[7] established a complete mathematical model of the overall efficiency of the solar chimney power plant system, and analyzed the main factors that affect the system efficiency.
Ming[21] presented a unsteady numerical simulation analysis of the effects of various parameters, such as storage medium properties, the temperature difference between day and night, on power generation performance of the system.
So, both of the two factors should be taken into account in practical project.
