As the measurement for impeller’s exterior shape and inner channel can’t be conducted in the same coordinate, 3-datum point location method is usually adopted in engineering for the alignment of multi-view point cloud data [4].However, the point features of silicone mould are difficult to extract as it is a soft material.

What’s more, the material properties are as follows, modulus of elasticity E=1011Pa, density ρ=1200kg/m, Poisson's ratio μ=0.25.
In order to accommodate the flapping wing aerodynamic force and not to weaken the aerodynamic effect, two polymer rods of the prototype’s wings are placed to support the wing surface which is made of soft film materials shown in Fig. 7 (b).

Introduction Considering the serious serving condition of aluminum alloy pistons in high power density engine, the chosen aluminum alloy materials should own excellent room-temperature and high-temperature mechanical properties.
Hence, those aluminum alloy piston materials are usually manufactured by squeezing casting method with the addition of Si, Cu, and Ni elements.[1].
Presently, it is urgent to find the ways to enhance the wear and corrosion resistances of new aluminum alloy materials in service term by improving the surface properties of alloys.
