Friction is one of the predominant factors exercising strong effects in micro-forming.
Crystal organization of materials, lubricants and die coatings are important factors that exert strong influences on material frictional behavior.

As a result, the kinematic viscosity of lubricants affected the extrusion force.

The corrosion resistance was one of the key factors to determine service life.
Failure Factor Analysis Product Quality.
At present, the main work was to optimize or form the evaluation methods and acceptance requirements based on the key issues of tightness, dimensions, and collapse of pipes, mechanical properties and corrosion resistance of welded joints, and so forth. 5) It was suggested that design units, oil fields, manufacturers and relevant research departments worked together to screen corrosion factors, and clarify the scope of materials applicability further.

Drilling practice has proved that properties of the sediment around borehole are changed when mud invasion, such as strength and pore pressure [15].
The primary parameters and physical properties of the sediments in the simulations were shown in Table 1.
°C -1 Results and Discussions Time-dependent geophysical properties during the invasion of mud.
While the main factors which affect the mud invasion is the positive pressure difference between the borehole and sediment, the penetrability and the invasion time.
They interact on each other and together determine the degree of drilling fluid invasion and hydrate dissociation, which further influences the mechanical properties, pore pressure, water/gas/hydrate saturation, permeability, resistivity and wave velocity of the sediment around borehole.

The properties of feed have also a major impact on membrane fouling.
The properties of this fouling layer largely control the membrane performance.
The reversibility of fouling layer as well as the critical flux of suspensions appear to be dependent on hydrodynamic conditions and physicochemical properties [4-7].
The changes of pH, ionic strength and suspended solids concentration and the process condition of submerged ultrafiltration (e.g. air bubbles flow rate) affect the flux and properties of this fouling layer.
The details of the membrane fabrication process and its properties determination procedure could be found in previous study [15].

For example, the assembly force affects the characteristics of the contact interfaces between components.
Also, operating temperature is one of the key factors that affect fuel cell performance.
The dimensions and mechanical properties of the components are listed in Table 1.

The suitable technological condition of preparing high strength composite ceramsite was given by studying the influence of the different mix proportions and different sintering systems on the properties of ceramsite.
The XRD(X Ray Diffraction) and SEM (Scanning Electron Microscope) analyses show that a large number of amorphous gel phases which affect the strength of ceramsite were produced in the process of sintering fly ash and waste glass and abundant even bubbles were formed inside of the ceramsite.
Some experimental studies about the preparation of the ceramsite using solid wastes, such as fly ash and sludge, were reported [7-10], but the products always had the poor mechanical property and high water absorbing rate.
The composite bubble-forming agent(A), the composite binder(B) and the roasting temperature(C) are selected as the three factors, the three levels of A are 5%, 10% and 15%, the three levels of B are 5%, 10% and 15%, the three levels of C are 1100°C, 1140°C and 1180°C.

At present, system research on performance of the physics, deformation, strength and other properties of light mixed soil already exists in China, but the study on permeability is just in the initial stage and the system study on permeability of EPS beads-mixed lightweight soil is lack of, therefore, it is necessary to study the permeability of EPS beads-mixed lightweight soil.
At present, physical, deformation, strength and other properties of lightweight soil have been systematically studied in China[1]-[6], but the study on permeability is just in its infancy.
The specialized research of permeability is essential for permeability is one of the important mechanical properties.
In the other factors fixed cases, different EPS particle mixing ratio coefficient of permeability coefficient of correlation equation of R are 0.9728, 0.9272, 0.9522 and 0.9762, with8 %, 10%, 15% and 20% of cement admixture.

Introduction The landslide is a common natural geological disasters, collapse of the mountain formed after a landslide and debris flow caused by storm often cause serious damage to the national construction and the people's lives and property if monitoring the landslide and realizing landslide hazards early warning, we can minimize and prevent losses caused by the landslide.
If not timely and comprehensive prevention and treatment, it is bound to affect the safety of the lives and property of the people and the sustainable development of the national economy.
Landslide is the natural phenomenon that soil or rock mass on the slopes subject to river erosion, groundwater activity, earthquakes and artificial cut slope factors,sliding down integrally or dispersed along certain weak surfaces or weak zone under gravity, commonly known as "go mountain", "collapse mountain", "soil slip" and so on.
Landslide formation conditions ●The topography: slope height, slope, shape and causes influence; ●Formation lithology:combination of soil and rock;soft and hard rock interbedded ;uniform geotechnical body through jointed surface; ●The geological structure: tectonic belt rock crushing; tectonic structure surface (joints,faults, bedding, strata, unconformities,etc.); strengthen groundwater activities tectonic zone; ●The hydrogeological conditions:lubrication;aggravated dynamic and static water pressure;seepage erosion; ●The impact of human factors and other role:destruction of vegetation, large cut big dig, blasting.
