The whole variable features and regularities of geo-stress field are summed up in Xiluodu deep-cutting gorge. The results reveal that the major and minor principal stress of measure point increase lineally with the vertical depths in the gorge area, and also indicate that the coefficient a〓, a〓, b〓, and b〓 of the linear equation are changeable with the erosion depth of rock mass.

认为该峡谷区中，谷河底部最大、最小水平应力量值总体上具有随深度增加而线性增大的特征，但其线性方程的系数a〓、a〓、b〓、b〓，随地表高程的低高或者说河谷侵蚀厚度的深浅而变化；岸坡山体中仅存在应力降低区和应力相对平稳区而没有明显的应力增高区，应力降低区与应力相对平稳区的分界线在水平埋深135～165m之间。

So the business enterprise want value product of quality, but product quality usually from several what quality index sign influence, so this text define the quality of product first, quality for modern business enterprise of importance degree, and influence quality of factor, and the content and quality of quality of future carried on introduction; And then combine introduction impact factor of product quality, and point out to will have several quality index sign influence product in actually of the production of quality, and of quality index sign would also mutual influence, thus the derivation diverse mass defect model, and introduction it of function.
