英文: A branch and bound algorithm for solving a class of nonlinear 0-1 knapsack problems is proposed, in which branching is common 0-1 variables one and a better feasible solution is found by a simply integer heuristic method as well as a lower bound of the op
中文: 摘要构造出了一类可分离非线性0-1背包问题的分枝定界算法，分枝的过程是普通的0-1变量分枝，用简单的取整启发式法确定更好的可行解；而在每个分枝结点处用线性松弛技术确定了它的子问题的一个线性规划松弛逼近，由此得到最优值的一个下界。

英文: By altering the length of some structural members while keeping the prestress level above a given lower bound without relaxation, the nodal displacements of prestressed cable structure are controlled.
中文: 在保证预应力索结构各索段一定的预应力水平且不致松弛的情况下，通过改变结构中某些索段的长度，来达到控制节点位移的目的。

英文: By means of variational structure and Z2 group index theory, we obtain multiple solutions of boundary value problems for second-order ordinary differential equations and lower bound estimate for number of the solutions.
中文: 摘要本文利用变分原理和Z2不变群指标研究了一类二阶常微分方程奇异边值问题的多重解，得出了这类解个数的下界估计。

英文: Compare to existing results for general graph, new lower bound on the size of the minimum feedback vertex set of (n, k)-star graph is given based on its special structure.
中文: 本文主要讨论了关于组合星图反馈结点集的下界问题，在基于组合星图的性质和已有相关结果的基础上，给出了组合星图反馈结点集的新的下界。

英文: Degenerate slice indices are handled gracefully: an index that is too large is replaced by the string size, an upper bound smaller than the lower bound returns an empty string.
中文: 退化的切片索引处理方式很优美：过大的索引代替为字符串大小，下界比上界大的返回空字符串。
