Introduction With the availability of reliable large scale simulations of materials behavior, a principal challenge is the development of strategies for the extraction of information.
Furthermore, the same low index and slow growing surface orientations that dominate the external forms of the materials are also the preferred grain boundary plane orientations [4-6].

Introduction Functionally Graded Material (FGM) are totally different from the conventional material in such a way that in FGMs the structure and properties vary from one end of the casting to the other end whereas in conventional materials the structure and properties is assumed to be uniform over the entire specimen[1].
The centrifugal force progressively increases the volume fraction of the Si and Cu reinforcement within the liquid Al matrix along the length of the specimen, owing to the density difference between the three materials (ρAl =2700 Kg/m3 and ρSi =2300 Kg/m3, ρCu =8920 Kg/m3).

Among many available models of anisotropic materials for plane state of stress and strains, the most frequently used are Hill’s [1], Barlat, Lian’s [2], Banabaic et al. [3].
The material constants (Young's modulus E, Poisson's ratio ν) assigned to type 20 material do not cause its elastic properties.

Introduction ZnO was one of Ⅱ{TTP}8545 - Ⅵ{TTP}8549 clan directly broadband gap semiconductor compound material as the third generation of semiconductor materials.
Doped ZnO nanomaterials can further improve the electro-optical property, so materials which doped metal on ZnO thin can reduce the resistivity.
This phenomenon make visible region photoluminescence peak relative ultraviolet photoluminescence peak weakened dramatically, therefore Al doped ZnO nano national materials can be used widely in ultraviolet luminescence device.

The position and function of library in colleges and universities of agriculture Library in general is an institution of collecting and organizing books and materials for people to read and consult.
The service of libraries has transited quickly from monotonously providing materials to providing both materials and information.
This mode is oriented towards a kind of simple information request, and provides printed materials stored in the library.
In addition, staffs providing information service shall be compound talents with knowledge in collecting materials, knowledge in foreign languages, and knowledge in special disciplines.
