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.

所以企业要重视产品的质量，而产品质量通常是多个质量指标所影响的，所以本文首先对产品的质量的定义，质量对于现代企业的重要程度，以及影响质量的因素，以及质量的内涵和质量的特性等进行了介绍；而后并介绍了产品质量的影响因素，并指出在实际的生产中会有多个质量指标影响产品的质量，并且质量指标之间也会互相影响，从而引出多元质量损失模型，并介绍了它的作用。
