In order to process the optical crystal materials with high precision, we developed a magnetorheological finishing prototype.
It combines the electromagnetism, fluid dynamics, materials science and optical processing theory together, and provides a precisely way to control the removal amount of the material [4].

The raw materials Y2O3, BaCO3 and CuO were mixed, ground and react in the air atmosphere at 950 °C, at 980 °C for solid state reaction and melt process, respectively.
Experimental Procedure The YBa2Cu3Ox (Y123) and YBa4Cu5Ox (Y145) powders were synthesized by solid state reaction and melt process that the raw materials Y2O3, BaCO3 and CuO (99.9%) in the desired atomic ratio as 1:2:3 and 1:4:5 were used.
The Y2O3, BaCO3 and CuO (99.9%) were used as raw materials The samples obtained were characterized by SEM, EDX, XRD, DTA and four-point probe technique.

The stress, displacement and acceleration of the lining in different materials are got.
The three models have same rock and fault material, but the lining materials are different.
When using c40 as lining material, the displacement decreased 27% at the position of fault, but increasing 1700% at the tunnel entrance. 3 conclusions Three finite element models are built by using different earthquake-resistant materials.

In this study, PAN-CF with good mechanical property, adsorption, and high-temperature resistance was used as the carrier, TiO2/SnO2/CF composite photocatalytic materials were prepared by sol-gel process and diping sintering method, and the catalytic properties was studied. 1 Materials and methods 1.1 Materials PAN-CF (T300C) with diameter of 5~6.5 μm was manufactured by Toray industries.
After that, the change of the concentration of degradation solution is result from the catalytic degradation for materials.
