Deformation process of slope has been controlled by a variety of factors due to the unique geological, hydrological and meteorological conditions.
Introduction Deformation process of cutting slope is controlled by a variety of factors in addition to its internal geological control factors during the high grade highway construction and operation, but the external agency is the key factors affacting ing the development of slope deformation[1, 2].
Huge security risk is formed for highway construction and traffic and normal construction of roadbed is seriously affected.
Due to the influences of structure, there are crashed rock structures, and with intensive developed joint fissures. the main distance is about 5cm~20cm.The rock has the characteristics of gravel soil, because of argillaceous shale and carbonaceous shale mainly contain clay mineral, rich smectite and kaolin, completely decomposed shale and its weathered products has the character of high liquid limit soil, dry shrinkage and wet expansion characteristics, under normal circumstances the engineering performance is available, but after several alternation of drying and wetting its mechanical properties decrease, because of weathered rock mass has the character of cataclasite, so it’s easy for rainwater infiltration ,evaporation and discharge.
The main material components of slope were completely decomposed shale and its weathered products, controlled by structure and weathering factors, joint fissures of the slope rock mass intensive developed and rock structures are crashed, it belongs to the category of cataclastic rock mass.

From the compression stress-strain results, carrier fluid viscosity was significant to vary the MR fluid properties.
Introduction Magnetorheological (MR) fluid is a suspension of micron-size magnetisable particles dispersed in a viscous medium with controllable rheological properties.
Their findings show that the MR fluid under squeeze mode exhibit different performance under different materials properties and squeezing parameters.
Among the factors which affect the separation phenomena were, viscosity, particle size, squeezing speed and applied magnetics/electric field [5].
The predicted factors-response relationships from the models are given by the following equations.

A higher oxygen content can create a more reactive deposition environment, influencing not only crystal density but also other properties such as crystallite size, surface roughness, and even the optical and electronic properties of the [17].
This may be attributed to the high oxygen pressure affecting the structural properties at the surface of the film during deposition, leading to a reduction in crystallite size [17].
In addition, several factors are involved in the transmission of the films, such as grain size, structural homogeneity, crystallinity level and surface roughness [25].
Furthermore, the increase in the O/Sn ratio, observed in the EDX spectra, shows that controlling the oxygen concentration allows for the adjustment of the material’s properties, which can directly affect its efficiency as a photocatalyst.

Ball-end cutter reflect the different cutting force when processing different shape feature of surface, thus affecting the surface processing quality, efficiency and tool life.
The distribution and number of the cutting blade units is the key factor that affects the cutting force when processing different feature of surface.
After analyzing the property of cutting units and its distribution, the basic tool cutting force model can be created [4].
Tool path generation is the key factor for Surface boundary processing.

It mainly because the strength of adhesion of the films is very strong and the strength of adhesion is the premise of various performance of the films.The coatings of Al have effective corrosion resistance, compare with the coatings of Al , the coatings of Cu have much better heat-transfer properties.
In the magnetic refrigeration machine, the property of heat exchange response to the efficiency of refrigeration.
The effective factors is that A is stronger than B and B is stronger than C.
The effective factors is that C is stronger than B and B is stronger than A.
(2) The adhesion between Cu and Gd is very bad and they are bonded together only by mechanical link.

The hot runner system is becoming an important direction of the development of hot plastic injection molding but is far from the stage of popularization in China, and the main reason is the design of hot runners involves many fields like material, structure, fluid and thermal deformation, with lots of influencing factors, and not only the experience and knowledge of predecessors but also the knowledge of scientific calculation shall be used.
Check the sprue diameter and determine the optimal sprue diameter according to the plastic properties; Step8.
A pair of conflictive factors is taken in the consideration of the runner design: reducing the pressure loss in the runner requires larger cross-sectional area of runner; reducing heat loss requires a small surface area of runner.
Determine the layer property of runner plates and suitable runner plate structures according to the selection of cavity arrangement; Step2.
Since the hot nozzle works in the molten state of the plastic, the nozzle expands apparently and the thermal expansion affects the position relationship between the nozzle and the cavity.

The material properties for the ray tracing simulation are shown in Table 1.
There are only two factors of the approximate spherical reflector, which are radius (R) and approximate factor (s).
The factors and levels are listed in Table 5 and the results of simulation are shown in Table 6.
There are four factors and three levels in the simulation (Table 7).
The radius of arc surface r and the radius of approximate half sphere R are the factors of the largest effect.

The dMNs were evaluated for physical appearance using a digital microscope, mechanical strength using a texture analyzer.
The dMNs were evaluated for the physical and mechanical properties, dissolution times, ocular penetration depth, and in vitro ocular permeation of fluorescein sodium through the porcine corneal tissue.
The physical appearance and mechanical strength of the dMNs were evaluated.
Polynomial equation in terms of actual factors: Maximum tolerance force (Y1) = 16.48 - 1.17 X1 + 3.91X2 [1] Needles height (Y2) = 567.00 - 24.74 X1 + 14.86 X2 [2] Table 2.
