This paper determines the design idea of combining VISC with structural optimization design. Problems which existed in structural optimization design are analyzed and contents of optimization process are determined. Calling and dominating calculation program written in FORTRAN in the development environment of Delphi are realized by the techniques of FORTRAN/Delphi mixed-language programming and multi-threaded application. Parallel coordinates visualization technology is deeply researched and applied in software exploitation of optimization process. Essential programs of VISC software are compiled. Approaches which can improve efficiency of optimization are discussed. In the end, functional modules are integrated and a typical computational example is verified.

This article tries to analyze the depth and breadth of Chinese modern national character research in theoretical perspective; The theoretical visual angle it chosen is a kind of cultural comparing research macroscopic threshold;"The Chinese question" globalization goes through the historical perpetual flow; Standing on such dynamic platform, this article reveals multi-dimensionality meanings of cultural anthropology, sociology, psychology, politics and ethnology which the question refers to, and analyzes the thinking course of modern people seeking conscious liberation; It resets the national character question into the space which Chinese modern national politic salvation and culture enlightenment exist in to prove the national character's social value; Furthermore, it opens up and develops the profoundly influencing inertia, which is implicated in the generation's considering, inheriting, criticizing and innovating, thereby it gains some enlightenment of persons modernization through regressively examining.

Comparing with existing solutions, new method can utilize generators' speed signal measured by wide area measurement systems directly and detailed model and parameter of power system components were not needed. After sphering measurement-data, ICA with maximal negentropy criterion was carried out to obtain feature matrix. By this means high-dimension data of multi-machine perturbed trajectories were reduced to lower dimensions, and coherent generator groups were identified by pattern recognition consequently. Simulation results of 36-bus system with 8-generator and planning northwest China 750 kV power grid show that noise signals and bad data can be eliminated. This method is accurate in identifying coherent generator groups.
