The lattice parameters of the material were calculated by MDI.Jade.5.0 soft, the lattice constants of the simple are: a=10.310Å, b= 6.001Å, c= 4.687Å, that is very close to the standard LiFePO4 data.
The uniform distribution of the carbon and appropriate reduction of the particle size can significantly improved the diffusion rate and the conductivity of the LiFePO4/C [6].

Fig. 4b shows broadening diffraction peaks of the porous film, which implies a reduction in crystalline size.
The barrier height () and the ideality factor (n) can be determined from the y-intercept and the slope of the fitted curve, respectively, by using a linear curve fit to the forward characteristics of ln(I) against the V data.

In addition, there are reduction factor exist: when rock and tunnel has an angle of 10 to 20 degrees, the factor is 0.8, and hence for IV category rocks, it can only withstand 1.6 to 0.45 MPa of pressure.
Now, the slope of those three pitshafts are 22, 25, 25 degree separately, and according to drilling data the angle of drilling is 17~18 degrees.

Under the arid climate, both dry and little wet saline soils have melt sinking features, which will be melt sinking deformation and got strength reduction under the soils’ weight pressure or supplementary pressure of the earth surface [4].

However, further reduction of these large epitaxial defects is required in order for SiC devices to handle higher power densities.
With respect to the data in Table 1, 27 sites where TSDs existed with the morphological feature were checked, and it was confirmed that extended defects appeared in 21 sites.

Enter the main data of each part and the related physical parameters, the whole engine model is showed as fig1
Fig.1 The GT-POWER model of one type of piston aviation oil engine
Change the air inlet conditions when the altitude reaches 5000 meters where air pressure and temperature declines, the temperature was 254K, temperature pressure was 50.545KPa
Simulations show that the air compress efficiency decreases. from 100% to 30% when works at high altitude from sea level to 5000 meters.
