Therefore, it is necessary to conduct the basic research on the tribological properties of the matching materials of the roller and guide tribo-pair in the thermal environment in order to optimize the engineering design of the roller and guide tribo-pair in the antenna.
At present, the rollers in the space antenna pulley system are mainly made of metal materials such as alloy steel, and the guide rails are made of carbon fiber and its fabric as an epoxy resin material for reinforcement [3].

However, the wearing of polishing wheel has introduced much larger diameter excursion comparing to grinding wheel in long term operation [3], since the filling material of polishing wheel mainly was epoxy resin, while the materials for diamond are nickel, brass or other metal alloy.
P is the elastic force between raw materials and polishing wheel, V is the line speed between raw material and the surface of polishing wheel.
Vertical axis Z directly controls the precise position and force during polishing operation according to different size of raw material.

(ii) Electrospinning of the prepared solution at the appropriate conditions, preparation of the precursor nanofibers containing ceramics precursor and polymer assistant materials.
Experimental Materials and Methods The preparation of ceramic SnO2 fibers contains 2 steps and starts with the electrospinning of the precursor fibers.
Raman spectroscopy is a useful tool for the characterization of materials (also on the nanosized level) and is a qualitative probe of the presence of lattice defects in solids [8].

Information concerning resources, products and processes are gathered on a high detail level e.g. on a material number level.
Rather the consideration of product and resource groups, which contain different material numbers or resources is reasonable.

Introduction In the previous photocatlytic materials, the core element of representative photocatalysts are confined to d0 type transition metal ions such as Ti4+, Zr4+, V5+, Nb5+ and Ta5+.
Moreover, many transition metal compounds have good photocatalytic property because these materials have energy level hybridizations and discrete energy band near Fermi surface.
The influences of calcination temperature and PH value on the photocatlytic properties of as-prepared materials were also studied. 2.
