Microfluidic chips, which are of excellent properties and for biochemical testing, are researched and manufactured in this paper. The biochemical reactor cells and microchannels in glass substrates of microfluidic chips are fabricated by processes of doping, photomask and wet etching etc, surface morphology and surface roughness are measured by the stylus profiler; at the same time sample-input through-holes...
Fuzzy net is of advantages that every node and parameter has distinct physical meanings and can describe the proposition and subjection of Petri net. Neural net has the ability of learning and self-adaptation, so it can be possible that the proposition of input place converges to output transition. Petri net which has the structure of fuzzy net and neural net can describe output transition as the...
The passive structural health monitoring system is built based on the theory of acoustic emission in this paper. According to dispersion properties of the Lamb wave propagated in the thin materials, Morlet wavelet transform and energy wave crest are used to calculate the time delay among different sensors. Structural damage locations of glass fiber reinforced composites (GFRP) H60 and P60 are researched...
Hierarchical structures of product design and models of components based on the theory of Green Product Design are defined after product disassembly processes have been analysed. In order to resolve combination explosion of product disassembly sequences, it is put forward that the unreasonable disassembly processes can be reduce by the three factors that connecting indexes among components, material...
