【Abstract】 By means of pattern recognition technique the principal parameters affecting the draw defect of automobile cylinder block cast are extracted in this paper. The available optimized quantitative range of these parameters are also determined. It has been demonstrated that the mentioned optimization technique can be acted as a technical approch to analyse the factors affecting the draw of cylinder block cast of automobile engine.更多还原
