The discussion covers: 1、By theoretical analysis on the measurement circuit of the piezoelectric accelerometer, a optimization design for charge amplifier is proposed which uses TL081 to replace a largenumber of discrete components. The design not only improve the integration of the circuit, but also have some extra merits, including smaller volume, lower consumption, less autoeciousness and stronger resistance to interruption. 2、Affiliated conditional circuit and filter to the devised charge amplifier, the signal is normalized and the noise ( generally, high frequency signal and DC signal) are restrained.

There are three platinum catalyst micro channels which have different width ,such as 1000 m , 400m and 40m. The platinum catalyst micro channel reactor is fabricated by MEMS technology. The reactor uses the exothermic reaction of hydrogen and oxygen on the platinum catalyst plate as the heat source and the platinum thin film resistance deposited on a glass chip by face micro machining process as catalyst and temperature sensor. The channel is bonded with a cover plate etched by bulk micromachining technology to become a mico- channel reactor.
