Introduction The analysis of functionally graded materials has become a subject of increasing importance motivated by a number of potential benefits from the use of such novel materials in a wide range of modern technological practices.
As it is reported in the literature [6, 7], the graded materials are rarely isotropic because of the nature of techniques used in fabricating them.

metallic bonding materials, organic bonding materials, and resin bonding materials.
Its kerf loss is small so that it can improve utilization of materials and is particularly attractive for machining expensive hard and brittle materials.
According to the bonding materials, there are three basic categories of diamond wire saws, i.e. metallic bonding materials, organic bonding materials and resin bonding materials.

Then, a concrete 'super fuzzy' feature model combined by four cent-characteristics for fabric materials is obtained, and this model is optimized.
Finally, after some programs experiments, concrete effect of fabric materials defects denoted by 'super fuzzy' feature is validated.

The experiment and simulation results indicated that this model could explain the drying process of grain materials well.
Experimental Materials and Method The corn, as a kind of typical grain materials, was the study object of drying simulation in this paper.
As said above, the grain materials included two kinds of different scale pore system at least.
The program generated the pore network physical model based on the structural parameter of grain materials.
