In this paper, it is put forward to choose main modes based on their properties and their contributing ratios, then the control for reducing seismic response is proceeded in the subspace of main modes by LQR technology.

The main and important technological points of WL-CSP are compared and researched in more detail so that the technological superiority and the application prospects of these new package technologies are shown.

According to the characteristics of the wastewater from papermaking, combined with the technological advantages of activated sludge process with deep well aeration, it is suggested that deep well aeration is promising and applicable for the wastewater treatment in pulp and papermaking industry.

According to the national classification of high-technology industry and the catalog of high-technology products,it gets sixty-nine industries as the research objects,and makes quantitative research on the selection of high-technology industry development for central areas from the point of industrial advantage and technological advantage.

This paper analyses systematically the technical development trend and characteristics, R&D structure of different enterprises, international technological gaps and competitiveness of China s densely technological industries by technological advantage sectors analysis in manufacturing.

The experimental results were used to calculate material properties, using the finite element method combined with optimization techniques.

As a new optimization technique,coupled local minimizers(CLM) possesses a high search speed and global search capability.

Meanwhile,by introducing the lowest energy theory and optimization technique to the failure diagnostic equation of ground network,the problem of morbid equation solution has been effectively solved.
