By using the concepts of absorbing sets, attractor and squeezing properties, the occurrence of complete synchronization of two high frequency coupled 2D Navier-Stokes equations is proved.

The method proposed here is based on the boundary and squeezing properties about Chen system.

Compression properties indexes including elastic modulus, failure force, failure stress and failure energy were obtained by the compression test of rice grain, and the effect of loading rate on compression properties indexes of paddy rice grain was studied.

The compression properties indexes of brown rice grain are important in design of harvesting, sorting and processing system.

The extrudability of wrought aluminum alloy was described in details and the evaluation on the extrudability of vavious aluminum alloy was carried out.

Study on extrusion modification of lentinus edodes dietary fiber;

2 Extrusion modification can change the functional qualities of soybean, compared to the soybean protein material, after extrusion, the WHC and OHC increased, but the emulsifying ability and foaming property reduced.

The microstructure,hot extruded property and mechanical property of a new type wrought aluminium alloy produced by adding several alloy elements to direct electrolytic product Al Si Ti complex alloy have been examined.
