On the second cutting stroke grains cuts into already processed material having roughness and forms a surface with a different topography.
The developed model is one of the main modules in complex imitating model of processes of grinding [9], and also was applied at research of opportunities of improvement of grinding speeds by assessing the machinability of materials [10].

It is mainly used in research on the dynamic mechanical behavior of high molecular materials and metallic materials and applies well in damping capacity test of metallic materials [10].
At present, it is mainly used for measuring the relationships between damping and temperature, and damping and strain of the high molecular materials and metallic materials.
This method applies to testing materials with a fixed damping value.

The most common drying method employed for food materials to date was hot air drying.
When infrared radiation is used to dry moist materials, the energy of radiation impinges on and penetrates through the materials and then is converted into heat[4].
So, several significant advantages of this drying method includes high energy efficiency, uniformly heating on the materials, higher drying rate and better final quality products compared with hot air drying[5].
Materials and Methods Materials Fresh ripe Cornus officinalis were provided by Luoyang longmen agricultural products base in the province of Henan, China and was stored in a refrigerator at 2~4 oC.
