接着，利用函数的上次微分构造了不可微向量优化问题（VP）的广义对偶模型，并且在适当的弱凸性条件下建立了弱对偶定理。
Finally, the generalized dual model of the problem (VP) is presented with the help of upper subdifferential of function, and a weak duality theorem is given.
本文给出了空值环境下的完全函数依赖的弱保持、强保持及部分函数依赖。
The weak and strong holds of Full Functional Dependencies and Part Functional Dependencies under the null values environment are proposed in this paper.
分析表明，承压含水层中地下水水头波幅是上、下弱透水层贮水率和越流系数的减函数，是淤泥层相对透水系数的增函数；
The amplitude of the head fluctuation decreases with the storativity and leakage of both semi-permeable layers and increases with the leakance of the silt-layer.
