质量损失的成因分析及估算

The Analysis of Forming Factors and Estimating for Quality Loss

对引起产品质量损失的原因——质量波动进行了分析.通过对质量损失函数中质量特性分布标准差σ的分析,表明标准差σ是影响质量损失的根本原因.

To strengthen quality control and improve quality level, this thesis analysed three sources of interference which have being aroused quality fluctuation and loss, then drew up the function of quality loss. Furthemore,getting a conclusion:it is σ,a basic factor,that influence the quality loss.
