In order to solve the contradiction of high speed and low accuracy of the precision stage,a micro-positioning mechanism with single degree of freedom and a high resolution was designed,which was guided by flexible hinge and driven by piezoelectric actuator.

A novel 2-DOF precision positioning mechanism consisting of two parallelogram chains drived directly by linear voice motors was presented.

With the quickly development of the IC industry,it is necessary to study a novel high speed and high precision positioning mechanism.

A novel inertial micro-actuator and its application in positioning mechanism;

Intelligent design of box part fixture locating devices;

Movement characteristics of micro-displacement mechanism with variable friction based on inertial impact principle;

Study on application of flexible hinge micro-displacement mechanism in tunable F-P filters;

We have set a system to drive impacted micro-displacement mechanism and archieve real-time data, acquistion and analysis.

Ultrastructural Localization of Echinococcus granulosus 66 kDa Antigen;

The ultrastructural localization of ATPase carried out,by using a lead phosphate precipitation method,on the chromosomes of the root-tip meristermatic cells in wheat.
