This article presents some basic rules pf the design of giant magnetostrictive actuators on the basis of analyses of working characteristics of giant magnetostrictive materials and basic structure and working mechanism of actuators using these smart materials．A giant magnetostrictive actuator is designed for the active vibration control under instruction of these rules，and its trait is tested．According to experiment results the actuator worked as the design objective required，verifying the validity and practicability of these rules．

Transdermal drug delivery is limited by the extraordinary barrier properties of the strarum corneum ，the outer skin．Conventional needles insert across this barrier and into deeper tissue to effectively deliver drug，but can lead to infection and cause pain，thereby reducing patient compliance． The authors have microfabricated very short microneedles that are sufficiently long to penetrate through the stratum corneum ，but short enough not to stimulate nerves in deeper tissue and thus should be painless． These microneedle are created with HNA (HNO 3 4-HF +CH3COOH)etching system ，a silicon isotropic wet etching．

Shoe last lS the solid form around which 3 shoe lS molded．Development Of CAD system for shoe last is the key solution to improve shoe last industry．This paper focuses on the key modeling technologies of shoe last CAD system．Firstly，based on Object-Oriented technology，the design model of shoe last is constructed．Secondly，the point based geometric model of shoe last is defined，the surface point data set after regular processing represent the design geometric and the surface model generated from the data set is used as result displaying and subsequent applications such as NC programming． Finally，the system model that denotes the framework of the whole CAD system is presented．W ith these three models，3 practical shoe last CAD system is realized successfully．

Operational principle of traditional AC servo motor system used for static position control was introduced．Problem of lacking precision when AC servo motor system was used for dynamic position control was pointed out．Causation of inaccuracy when traditional AC servo motor system was used for dynamic position control was analysed．Solution based On high-speed terminal feedback was given．

Model reduction is one of the important issues in the dynamics analysis of the multiflexible system ．The model coordinate of the flexible appendages added to the system is the reason that causes the order of the system too high．Therefore，the most important question of the model reduction is the selection of the component modes．According to the typical flexible spacecraft ，based on the component modes，the equation of the multi—flexible system is established．The relation of the component modes and system modes is studied．The number of the appendage modes is selected through the modal cost analysis and inner balanced method to build the reduction system．The result iS showed that the above method to build the reduction system iS feasible though MATLAB．

Three-dimensional parametric modeling of assembly was proposed through the re-de-velopment of Pro／Engineer by using Pro／Program．By using this technology，the modeling work can be further reduced，and the efficiency and quality of design will be greatly improved．As an example，three-dimensional parametric model of satellite antenna’S hoop truss was developed for structure design．

The printing CAD system uses halftone of color printing in order to show the effect of cloud in pringting images．Printing system generally adopts the amplitude modulation because of the speciality of printing crafts．That is to say gridding module-based halftone．In real printing thereasily exists moir6 because of regular gridding module．Trying many methods，people can’t completely avoid moir6．The printing CAD system contains a new method of considering hexagon-based seven circles as a basic halftone grid．Because of the speciality of seven centers of circle，it can not create regular line in any directs．Then it overcomes dependence of regular gridding on images itself．

Although injection machines have been used extensively in industry，only extruder research has been emphasized．A model of the melt conveying section of injectors was established and analysed by the finite element software．And the velocity distribution in the vertical section as well as the output of the injection machine was derived．Based on the results above，the geometrical parameters of the metering section of the screw were optimized to obtain maximum output and minimum energy consumption．The results，about 38 screws，demonstrated that the performance of the optimized screw is better than that of the standard screw．
