For example, about the relationship between the length of casting zone and the properties, some view within a certain scope, the casting speed, productivity and strip quality can be improved as the increase of casting length.
But the length is affected by roll casting force and diameters of roller, when it comes to a certain value, productivity will no longer change[4].
Another example, the knowledge and results of Fata Hunter and Hydro Test on microstructure and properties of thin-gauge high-speed casting are almost exactly opposite.
As for the aluminum strip samples in different casting process parameters, under conditions of rough grinding, intensive grinding, mechanical polishing and electrochemical polishing and final use of filmer anode technology to make metallographic samples.
The unevenness of deformation along aluminum strip thickness direction is due to the presence of friction in roller surface and aluminum casting strip as well as the deformation caused by the shape factor; at the same time incomplete dynamic recrystallized grains come into being in the outer metal of the aluminum strip.

Yaw exciting force directly affected by the whole mechanical properties and its service life, and therefore it has an important significance to study the vibration characteristics of the wind turbine at yaw state.
Because the No.1, No.2 sensor was located in the front of generator and close to the rotor, so the similarity of vibration spectrum and static spectral affected by the vibration characters of rotor was related well.

Essentially, ideal BTE is the one mimicking native bone morphology and thus it is a common notion to use combination of porous scaffold, growth factor, and stem cells in order to obtain the regeneration ability of bone graft.
Thus, it is hypothesized that collagen fiber alignment could affect nucleation and growth of ice crystals and further affect the subsequent formed porosity.
Different viscosity of these two samples thus affecting the movement path of HMCP.
It is hypothesized that HMCP movement could align collagen fiber and thus affecting the subsequent formation of pores.

Many scholars had done a lot of researches of concrete -filled steel tubular arch bridge to the structure’s mechanical behavior, selection form, creep performance and other static properties ,got a series of research results[6-7].
Damping is a key factor of structural dynamic characteristics, its value directly affects the size of the dynamic response.
Many studies showed that the structure's damping properties and stress state had a greater relationship, the value of the damping ratio was not fixed.

This is that alumina affects the strength characteristics of proppants, and silicon oxide affects the elasticity when molding material granules.
It is these factors that do not allow widespread use of this proppant.
The disadvantages of this type of proppant are considered: low mechanical strength (6500 psi or 44.82 MPa) and high bulk density (more than 1700 kg/m3).
These factors and intermittent cyclic loading can reduce the fracture toughness of proppants.

Aerodynamic characteristics analysis of high-speed train on cutting under crosswinds YE Kun1,2,a,LI Renxian1,b 1School of Mechanical Engineering, Southwest Jiaotong University, Chengdu, 610031, China 2China Aerodynamics Research and Development Center, High speed Aerodynamic Research Institute, Mianyang, 622000, China ayekun2008313@163.com,brxli@home.swjtu.edu.cn Key words: High-speed train, Crosswinds, Cutting, Numerical analysis Abstract: Cutting is an effective device to reduce crosswind loads acting on trains.
The cutting depth, width and gradient of slope are important factors for design and construction of cutting.
Strong crosswinds cause a serious threat to safety of railway transportation and people's life and property [1-7].
Effect factors of cutting on transverse aerodynamic forces mainly include the following three aspects: (1) cutting depth; (2) cutting width; (3) gradient of cutting slope.
The cutting depth, width and gradient of slope can affect aerodynamic side forces and yawing moments acting on the train.
