The nation has to adopt to a serious of the measures to simplify the officers and workers significantly,cut down the high school,low to solicit students,compress the town residents in order to spend the famine.

In recent years,the personnel simplification has been a trend of organizational transformation, and private and public departments are sparing no efforts of simplifying its personnel.

This paper presents a reduced VLSI architecture of one-dimensional discrete cosine transform (1-D DCT) algorithm by introducing a fast algorithm with a matrix transform.

A fast and efficient condensation method from contour data has been provided, in which those edge points which have curvature extremis are extracted as initial segment points firstly, the generation of dominating points on the contours by two parameters (area error and equidistant sampling threshold value) between two segment point.

Discussing technical revolution and globalizing with the issues occured in the process:"downsizing" and its social inpact, recalling and anylyzing the devefopment of the world economic after the World War II, the Western scholars have suggested or advised on solving the above problems.

Point data reduction technique in reverse engineering;

In order to increase calculation speed of reconstruction, reduce memory space, and, at the same time, emphasize modelling characteristics, a method of data reduction with triangular folding was proposed by using triangular meshes model and ordering function on the basis of analysis of data reduction method available.

In order to reduce the data point-cloud of auto panel die’s surface acquired by non-contact 3D measurement, a kind of data reduction method is presented based on the average point-to-point distance principle.
