A new chance of developing traditional manufacturing industry comes forth with the development of network technology. Application technology oriented rapid response manufacturing in the distributed network environments, that is, how to take advantage of the Intranet and Internet, combine the numerous manufacturing resources spread around the region, the country and even the globe is the key to the agile design, manufacturing and the buildup of comprehensively competitive power, at the same time, is also an important research direction in the field of advanced manufacturing technology. Rapid response manufacturing in the distributed network environment is a newly manufactory pattern that can be used to implement the conception of agile design and manufacturing, but there are some new problems coming with it, which will directly influence the enterprise’s ability of rapid response in the distributed network manufacturing pattern and lead to the failure of the league and the lost of the given orders. In this paper, we establish some approaches to solve these problems in product development process. the paper then presents the research on key application technologies and solutions includes: network safety strategy which guarantees data transferring among the leaguer members, production data management based on Web/DOt (Distributed Object technology) and XML criteria which guarantees data exchange in structure-variance characteristic environments, the network platform which provides the conversion service of different types of CAD files each other. All of these solutions are aim for technology problems existing in the distributed network environments and among the league members. Finally, the paper takes one project, that is, the establishment of the online application service system for Shanghai Advance manufacturing technology Research Center as a good instance.

＜正＞ At present, the most common micro/nano-scale fabrication processes include the plane silicon process based on IC technology, stereo silicon process, LIGA, quasi-LIGA based on near ultra violet deep lithography, MEMS, energy beam etching and micro/nano-machining, etc. A common problem for these processes is the difficulty to fabricate arbitrary form for 3-dimensional micro/nano-parts, devices or mechanisms. to develop advanced MEMS manufacturing technology, and to achieve fabrication of true 3-dimensional parts, devices or mechanisms, this paper proposes a nanofabrication technology for rapid prototyping of 3-dimensional parts, using plasma chemical vapor deposition （PCVD）. this process can be describes as follows;A laser beam is produced by a low power, quasi molecule laser. It enters the vacuum chamber through a window, and is focused on with the substrate surface. A gas in the chamber is ionized by the laser beam to produce PCVD on the substrate surface, and forms a particle of the size of Φ100 nm （its thickness is about 100 nm）. When the laser beam moves along X-axis, many particles form a line. then the laser beam moves one step in Y-axis to form a new line. A plane is completed by many lines. then the substrate moves in Z-axis to form new plane. Eventually, many planes form a 3-dimensional component. Using available CAD/CAM software with this process, rapid prototyping of complex components can be achieved. A nanometer precision linear motor, such as that described in Chinese national patent （patent no. ZL 98 2 16753. 9）, can be used to obtain the nanometer precision movements in the process. the process does not require mask, can be used for various rapid prototyping materials, to obtain high fabrication precision （its scale precision is 15 nm）, and larger ratio of height to width of micro/nano-structure. It can find widespread applications in the fabrication of micro-mechanism, trimming IC, and fabricating minilens, etc.

the levered-dual response(LEDAR)Coulomb-damped system attains near resonant vibration isolation by differential preloads/offsets in linear *** takes the advantages of both the preloads/offsets in linear springs and the guiderail friction for realizing different levels of vibration *** isolation capacities are investigated on the strategies with both the horizontal and vertical guiderails,with the horizontal rail only,and without *** compressive preloads generally result in the consumption of most of the initial excitation energy so as to overcome the potential *** isolation onsets at the frequency ratio of 1∓0.095 on the left-hand side(LHS)and the right-hand side(RHS)of the lever are relative to the load plate *** observed near resonant isolation thus makes the LEDAR system a candidate for the isolation of the mechanical systems about resonance while opening a path for simultaneous harvesterisolation functions and passive functions at extreme frequencies.
