（4）The values of mechanical parameters will increase significantly after precipitation; As a result, the experimental data has great importance on optimization design and research about earth and water pressure

Furthermore it is assumed that the chamber (inclusive material of chamber) does not affect the properties of the elements on its inside.
If possible or necessary, a distinction in respect to the properties for evacuated and non-evacuated chambers is carried out.
Tab. 2 summarizes the estimated effects of different parameters on the mechanical properties.
The inherent rigidity and tensile strength as limiting factors can be neglected here.

The heat transfer and friction factor characteristics are significantly affected by the perforation density of the baffle plate.
Stehlik et al. [15] compared heat transfer and friction loss correction factors of an optimized segmental baffle heat exchanger to those of a helical baffle heat exchanger.
In their studies, the correction factors for helical baffles were examined as a function of baffle inclination angle to gain an understanding of the underlying transport phenomena as well as to characterize the baffle for design purpose.

Based on the experimental and calculation results between the reinforcing particles content and thermal physical parameters, low pressure die casting of wheels was taken as an example to study the casting property of the 7075 alloy and TiB2/7075 composites.
Numerical simulation has calculated the temperature field and stress field in mould filling and solidification process, defects and microstructure, which affected by the of gating system design and processing parameters, such as casting temperature, casting pressure, mold temperature.
The effect of grain refinement on the viscosity of composite depends on many factors of reinforced particle, such as itssize, shape, amount and even its agglomeration in the matrix[13].

The loss of alveolar bone may be attributed to a variety of factors, such as endodontic pathology, periodontitis, facial trauma and aggressive manoeuvres during extractions.
· Osteopromotion - involves the enhancement of osteoinduction without the possession of osteoinductive properties.
These morphologic changes may affect the successful placement and osseointegration of dental implants [4].
Commercially available synthetic bone replacements have been made of hydroxyapatite, tricalcium phosphate, calcium sulfate, and combinations of these minerals, and fabrication techniques, crystal configurations, pore dimensions, mechanical properties, and resorption rates vary [3, 14, 15].
Modification of their bulk structure, which brings their structure closer to natural bone tissue, including cytokines-growth factors and morphogens-into their composition enables to provide synthetic materials with not only osteoconductive but also osteoinductive properties.

Kim et al. [2] investigated the sensitivity analysis and showed that the change of process parameters affects the bead width and height more strongly than penetration.
First a full three level factorial design with 3 factors, with usual 0, 1, 2 notations is considered.

The interface temperature is not known a priori but depends on the intrinsic properties of the framework, in particular the thermal conductivity of the fluid and solid; and (iv) Newtonian heating, where the heat transfer rate from the bounding surface with a finite heat capacity is corresponding to the local surface temperature and which is typically named conjugate convective flow were demonstrated by Merkin [6].
The slip coefficients affect the velocity, temperature and nano focus as unmistakably appeared in Figure 4, 5 and 6 separately.
