Most small and medium-sized family enterprises choose the family management mode,and the owners of enterprises treat family-members and non-family members in a different way,which results in a different level structure and seriously affects the existence and further development of the enterprises.

In order to improve the kinematics accuracy of parallel machine tool and to simplify error resource model(including 42 errors),a new kind of algorithm on parallel mechanism structural errors reorganization is proposed in this paper based on the fast algorithm of parallel mechanism forward displacement analysis.

This paper puts forward the technique of reliability simulation for missile抯 flight control system under the influence of structural errors.

Separation and identification for structure error parameter in vibratory silicon MEMS gyroscopes;

Due to some factors induced by the fabrication technology and fitting process,the inevitable HRG structure error can affect the amplitude detection and control.

Due to some factors induced by fabrication technology and other reasons, the structure error and drift are inevitable , they affect measuring result and reduce accuracy.

The disturbance models of wind, structural errors (including missile mass asymmetry, body un-coaxial, airfoil installation angle error and rudder null position), thrust deviation and hardware failure are established.

This paper introduces the principle of CCD confluent measurement, analyzes and researches on various structural errors produced in CCD actual arrangement, and connecting with some actual test data, provides some crucial factors influencing the precision of the confluent measure ment, which possesses very important actual significance for the establishment o f the confluent measurement system.
