The deficits are in the specific grading standard, certain elements’ quantification is short of rationality, that the bidding agencies and the judges have a large subjectivity, which is difficult to ensure the justice of the biding, that the bid evaluation activities time is too short, the materials in the bidding documents can’t be comprehensively and carefully understood and grasped, and that the contents and standard of the bid evaluation is too full, which cause the bidding inviting organization’s stress on price doesn’t get enough attention[3].

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.
