Research on MEMS Phthalocyanine-Based Gas Sensor Liu Xin Department of Communication, Heilongjiang University of Science and Technology Harbin, Heilongjiang, China liu_xin1128@yahoo.com.cn Key words: MEMS; gas sensor; NO2 Abstract-A gas sensor based on MEMS (microelectro-machine system) has been developed to provide a sensitive means of detecting nitrogen dioxide.
Copper phthalocyanine (CuPc) is a macromolecule material,the resistance of which will change upon explosion to NO2.
So it is used as the sensitive material of NO2 [6].So far the detection of NO2 in practice has been carried out by using phthalocyanine thin film sensors based on MEMS.
The starting material was an N-type <100>-silicon wafer coated with silicon dioxide and nitride film on both sides.

Under ensuring the accuracy of the conditions, in order to accelerate the convergence of computing, on the material properties (such as specific heat) made the appropriate adjustment[4].
When the welding start, the weld material does not exist, it is gradually filled in welds.

Virtual Modeling and Finite Element Analysis of Flexspline Based on Solidworks Zhang Rong1, a, Yang Jiajun2, b 1Wuhan polytechnic university industrial & commercial college ,Wuhan, China 2Huazhong University of Science and Technology, Wuhan,China ameryer@sohu.com,byjjlar@sina.com Keywords: Harmonic gear mechanism.
Set the flexspline used in the known valve electric actuator , torque T = 50Nm, working smoothly, ratio u = 100, module m = 0.3, displacements coefficient xr = 3.37, material for 30CrMnSiA[3] .
In harmonic gear ,because flexspline is often effected by alternating stress, so the material of flexspline chooses the material of elastic, high strength .
The stress of the just wheel and the ordinary small module gear is similar.Flexspline chooses commonly used materials of low alloy steel and aluminum permeability nitrogen steel 30CrMnSiA. 3.

Even at constant processing parameters, the strength of green compact compressed from binary mixtures can often not be predicted from the compaction properties of the starting materials, because interactions between the materials may occur during the compaction process [3].
From this study, cellulose can be considered as a reinforcement material for iron-based component in the powder metallurgy industry.
