It can eliminate the jitter of target image due to the tracking error of telescope drive system, the mechanical vibration of telescope itself and atmospheric disturbance by its own rapid swing[2].The dynamic characteristic and surface of tip/tilt mirror directly affect the effectiveness of the tracking compensation[3,4,5].
To satisfy the performance requirements of mirror mechanics on this working condition and the surface accuracy under this mechanical properties, tip/tilt mirror must have higher first order natural vibration frequency.

Ink’s Properties Testing.
The value b means the biggest ink amount fills the substrate surfaces indentation by mechanical anchoring effect.
There are many factors effect the value b, and the main factor is the ink viscosity.
The main factor affects f’ is the rheological properties of ink[3].
The ink viscosity, yield value and ink silk length would affect the value f’.

The losses are due to several factors, including undesired conduction, radiation and convection losses, stack loss (fluegases), and metal loss.
Modifying the design and/or operation of any step in the melting process may affect the subsequent steps.
Loss of these elements will affect the physical/mechanical properties of the castings, leading to increased scrap and waste.
Gases that dissolve into the molten charge from the ambient air, combustion byproducts, and the furnace linings can also affect the final product.
