If you specify a nonzero , nonnegative value , the query governor disallows execution of any query that has an estimated cost exceeding that value 如果为该选项指定一个非零、非负的数值，则查询调控器将不允许执行估计成本超过该值的查询。
Secondly , we utilize the nmf ( non - negative matrix factorization ) algorithm to extract human face local feature subspace 然后,对获得的类人脸肤色区域利用nmf ( non - negativematrixfactorization )非负矩阵分解的方法提取人脸局部特征子空间。
Abstract : a parabolic system with nonlinear boundary conditions is considered . the existence and uniqueness of a nonnegative classical solution are proved to this problem 文摘:考虑了一个具有非线性边界条件的抛物系统,证明了这个问题非负古典解的存在唯一性
( 2 ) the equation satisfies the transient distribution of the waiting time w ( t ) is obtained , to which the minimal nonnegative solution is the unique bounded solution ( 2 )给出等待时间w ( t )的瞬时分布所满足方程，并证明它为该方程的最小非负解，也是唯一有界解。
Let be continuous and nonnegative on the closed interval . then the region bounded by the graph of , the - axis , the vertical lines , and is called the trapezoid with curved edge 设在区间上非负、连续，由， ，以及曲线所围成的图形称为曲边梯形，其中曲线弧称为曲边。
