Yang et al. reported that the sound absorption coefficient of rice straw-wood particle composite boards are higher than other wood-based materials in the 500-8000 Hz frequency range, which is caused by the low specific gravity of composite boards, which are more porous than other wood-based materials [6].

Since material is subjected to shear and friction action between the screw and the sleeve, as well as between the material and the material, so large amounts of heat is produced that the water in the materials is transformed into overheat water steam in a very short time, and in the compression chamber the high pressure is formed.
During the process of screw rotationally promoting materials, the force is large on the pressure surface of the helix, and the force is small on the non-pressure surface, so the load mainly was applied on the pressure surface.
According to the relation curve between materials compression ratio and pressure in the extrusion chamber, we applied load on the sleeve and the nozzle.

Using cation amino polysiloxane emulsion(ASE) and anion carboxyl polysiloxane emulsion (CSE) as materials, mixing ASE and CSE together to self-assemble or aggregate by electrostatic interaction, supramolecular compound emulsion (ASE-CSE) was formed.
Introduction The use of molecular self-assembly can not only obtain the molecular aggregates of higher order structure, but also construct the bionic materials, optoelectronic information materials and supramolecular liquid crystals[1,2].

It can negatively impact mechanical properties, corrosion resistance and other useful physical properties of materials.
This effect can cause engineering materials to underperform under service condition [1], leading to possible catastrophic failure.
The thermophysical properties of materials used in this work are those given in Reference 1 and 8 for Al-4.5%Cu.

Dynamic simulation analysis for processing of screw pump inside spiral surface WANG Ke1, a , LI Shan -shan 2,b, *, SHI Ya-jun3,c 1 Shenyang university of technology , shenyang , china 2 Shenyang university of technology , shenyang 110023, china 3 ShenYang YuanDa Enterprise Group，shenyang 110027,china a 110023, b110023, c110027 Keywords: object-oriented; Visual C++; inside spiral surface; milling；simulation ; model; interference examination；graphic display Abstract: In order to avoid or reduce the large waste of manpower and material resources in the practical test machining process , Based on Object-Oriented analysis &design this paper describes the research on simulation procession that CNC machine manufactures inside spiral surface by use of triangle model，And both Visual C++ and OpenGL are used.
However, due to the special nature of the screw pump rubber material often found easy to wear, easy to leak, short life of the defect, Processing the metal surface with a spiral inside the stator bushing replace rubber bushings as well to solve this problem[1].
Finally, using MFC class library available in the device description of the package class CDC, this class encapsulates all the graphics-related operations, the calculation of the cutting point before incorporated into VC + + program to implement within the spiral milling surface dynamic simulation. 4.1 Simulation Modeling For screw surface processing in the process, blank is a hollow cylindrical, with one of the machining process, material is gradually cutting.
