Reflector is a key function unit of THz radar systems, which often is made of metal materials.
It can directly manufacture large-scale optical mirror and some other complex curved surfaces (depth aspheric, off-axis aspheric, etc.) from a variety of materials (such as nonferrous metals, infrared materials and KDP, etc.), being a big challenge for traditional non-deterministic processing technology and equipments.
For different surfaces and materials, the optimal parameters are different.

The use of hot strip steel instead of part of cold strip steel in making automobile inner board has been considered for cost reduction of materials.
On the one hand, hot strip steel within the thickness of 2.0mm was considered for cost reduction of materials to get cold strip steel.

It will narrow the cost gap between the PV power generation and conventional power generation. 2.2 Weaknesses The production process of PV is of energy intensive and high raw material input.
Due to the constrains of the production technology in China, the average raw material consumption and energy consumption per unit of PV product is higher than the average in the world.
For instance, for producing 1 kg polycrystalline silicon in China, it needs 4 times of energy input, and much more raw material input than that required in the industrial counties, such as 4 times of silicon powder, 13 times of liquefied Chloride (Cl) and 90 times of Hydrogen, etc.
