查询词典 vector

Otherwise, there'd be a hole in the vector, and the vector elements would no longer be contiguous.

否则， vector 容器上将会留下一个空位，而 vector 容器的元素就不再是连续存放的了。

However, the Vector has an additional constructor argument, which is a Boolean value that specifies whether the Vector size is fixed or can be changed.

然而，Vector还有一个额外的变量，一个可以具体控制Vector长度是否可以改变的布尔值。

If so, then the member initializes an object in the next available spot in preallocated memory. If there isn't a free element, then the vector is reallocated: The vector obtains new space, copies the existing elements into that space, adds the new element, and frees the old space.

如果有，该成员在预分配内存中下一可用位置初始化一个对象；如果没有自由元素，就重新分配 vector： vector 获取新的空间，将现在元素复制到空间，增加新元素，并释放旧空间。

Objects in the vector are not named. Instead, they can be accessed by their position in the vector.

vector 中的对象是没有命名的，可以按 vector 中对象的位置来访问它们。

The vector subscript operator takes a value and returns the element at that position in the vector.

vector 的下标操作符接受一个值，并返回 vector 中该对应位置的元素。

Based on the analysis of the affected extent of the neutral-point potential by every space vector on all kinds of voltage and current conditions the concept named neutral point control grade was proposed for the first time in this paper. The calculation formulas of NPCG were presented as well. Based on NPCG, a novel modulation scheme called optimized 3D space vector modulation (O3DSVM) scheme was proposed in a-b-0 coordinates based on the translation principle of axes, by which the space vectors with higher NPCG values are selected to synthesize the object vector to suppress the unbalance of the neutral-point potential.

该文通过对各种电流电压状态下每个三维空间矢量对直流中点电位的影响进行分析，提出了"中点控制度"(neutral-point control grades，NPCG)的概念，并给出了NPCG的计算公式；基于NPCG，在a-b-0坐标系下提出一种基于坐标平移原理的新型"三维矢量优化选择调制策略"(optimized 3D space vector modulation，O3DSVM)，该调制策略能优化选择NPCG值较高的矢量以合成目标矢量，从而达到最大程度控制直流中点电位偏移的目的。

Function defined by vector that appends elements to the back of a vector.

由vector类型定义的成员函数，用于把元素追加到vector对象的尾部。

Note that because lines appear in ascending order, we can append a new line number to the vector only if the last element of the vector isn't that line number.

注意，由于行以升序出现，因此只有在当前行号不是 vector 容器对象中的最后一个元素时，才能将新行号添加到 vector 中。

Having walked through the code in detail, we can see that this program has exactly the same effect as the version that used subscripts: We start at the first element in the vector and set each element in the vector to zero.

通过上述对代码的详细分析，可以看出这段程序与用下标操作符的版本达到相同的操作效果：从 vector的第一个元素开始，把 vector中每个元素都置为0。

Methods(1) Construction of plant expression vector containing RS geneThe cloning vector pT-RS was constructed containing RS gene extracted from the leaf tip of Vitis vinifera by PCR amplification and RS sequence was identified by PCR amplification,enzymes digestion and sequence analysis.The plant expression vector containing RS gene was obtained and RS sequence was identified by PCR amplification and double enzymes digestion too.

研究方法(1)含白藜芦醇合酶基因的植物表达载体的构建提取葡萄基因组总DNA，通过PCR扩增得到RS基因，将此基因连接到克隆载体pGEM-T Vector，得到重组载体pT-RS；经PCR、酶切及序列分析鉴定后，将RS基因克隆到植物表达载体pBI121，得到重组载体pBI-RS，用PCR及双酶切方法进行鉴定。

Graf, without question, is the greatest women's player in history.

格拉芙，现在，毫无疑问是女子网坛历史上最伟大的选手。

If not, you will have to look around at all your important data.

如果没有，您将需要检查所有的重要数据。
