Different materials were adopted to simulate the roughness of saltation snow particles to get the distribution of wind velocity in the simple wind tunnel.
In this paper, different roughness materials are adopted to simulate saltation snow particles (Fig.1) so that velocity distribution in saltation layer can be gained.
Light difference appears among the velocity profiles for three different roughness materials.

Introduction Composite material is a structure which consists of two or more components of different materials that are mixed at a macroscopic level and are not soluble in each other.
These different materials provide the composite singular mechanical properties.
Fig. 1 is showing a pipeline installed on the ground and supported by curvature structure, to transfer liquid materials such as oil or water.

Introduction Titanium dioxide (TiO2) thin film is one of the most extensively studied materials due to its excellent properties, such as high transparency for visible light, high refractive index, controllable specific electric resistance and good chemical resistance [1].
During the last decade many researches are interested in TiO2 nano-thin film and their application which have been widely used in catalysis, solar cells, electronic devices, optical materials, additionally, it can be used as antibacterial surface because of strong oxidation activity [2].
