Aust group, the authors' group and others have been deeply involved in the development of high performance polycrystalline structural and functional materials on the basis of the concept of Grain Boundary Engineering since 1980's until recently [5-8].
It seems still premature for general application of grain boundary engineering for functional materials [12], but we may be able to provide a new step stone for future development of the grain boundary engineering for high performance polysilicon.

Data plays more and more important roles in the AEC field, especially in Nuclear power plant constructing and engineering.
In this paper, except introduce the basic DP theory and methodology, we analyzed the key points while doing the DP in nuclear power plant.
And it can work as an overall blue print for the information system development during the engineering process.
While working in the qualified information data environment, the technical and efficiency of nuclear engineering will be ultimately improved as well.
In the nuclear power engineering process, no matter the plant design, materials and equipment procurement, or the construction, installation commissioning business will generate mass of data.
