元素的

One common strategy is to preallocate a block of raw memory to hold unconstructed objects. When new elements are created, they could be constructed in one of these preallocated objects. When elements are freed, we'd put them back in the block of preallocated objects rather than actually returning memory to the system.

一个通用策略是预先分配一场原始内存来保存未构造的对象，创建新元素的时候，可以在一个预先分配的对象中构造；释放元素的时候，将它们放回预先分配对象的块中，而不是将内存实际返还给系统。

To avoid a common pitfall, always keep in mind that arrays (and all other LabVIEW structures) are zero indexedthe first element has an index of zero, the second has an index of one, and so on.

为了避免惯常的错误，始终记住在数组中（以及其他LabVIEW中的任何结构）都是从0开始索引的，第一个元素的索引值为0，第二个元素索引为1，以此类推。

Quadratic assignment problem is a NP-hard combinatorial optimization problem and has been applied in various fields. There are always many zero elements in the flow matrix or distance matrix of the quadratic assignment problem instances which are abstracted from the practical problems. Much computation time can be saved if we can first reduce the size of the problem by using its zero elements.

二次分配问题(quadratic assignment problem， QAP)是应用于诸多领域的组合优化NP-难题，许多从实际问题中抽象出来的二次分配问题，其流矩阵与距离矩阵中存在大量零元素，如果在该类二次分配问题的求解中，能够充分利用这些零元素的信息，将大大缩减问题的规模，节省大量运算时间。

从本研究的供试土壤来说，在不同条件下有机物的输入特点直接影响了土壤团聚颗粒的微生物活性，从而影响团聚颗粒中各种元素的分配与转化，因此它是促使土壤团聚颗粒环境中营养元素、重金属元素运移的驱动力。
