因而，我们可能要扩展我们的眼光，把我们的眼光从一维的&数轴&扩展到&多维空间&，把我们的分析工具从&标量&扩展到&多元向量&。

The BDDcFⅧ gene was ligated behind PUB and 20H1 promotors to create lentiviral vectors pTK161 and pTK162. Meantime lentiviral vectors pTK161' and pTK162' were produced by cloning a green fluorescent protein into pTK151 and pTK152, which was driven by PUB and 2OH1 promotors respectively. Vector supernatant were prepared by using transfer calcium phosphate mediated-cotransfection of 293T cells. The virus vector,△NRF packaging-plasmid, and VSV-G envelope-plasmid was assayed by titers and cFⅧ activity in cell culture supernatant after infection into 293T cells.

用构建携带cFⅧ基因的慢病毒载体pTK161和pTK162（含20HI启动子），同时构建含绿色荧光蛋白的慢病毒载体pTK161'和pTK162'（含2OH1启动子）的方法，分别与包装质粒△NRF、包膜蛋白质粒VSV-G共转染293T包装细胞，将包装好的病毒颗粒再感染293T细胞，检测病毒滴度和培养细胞上清中cFⅧ活性。

Second,. according to the sector of voltage space vectors, adjacent switching state vectors are selected to calculate on-durations under volt-second balance principle. The questions of judging sectors and sector transition are discussed and qualitative analysis of performance is carried out.

由三相电压源型逆变器输出电压波形得到六个有效开关状态矢量，这六个开关矢量和两个零矢量合成一组等幅不同相的电压空间矢量，去逼近圆形旋转磁场。

The experimental results indicate that the improved algorithm can describe feature points in a larger region, and can reduce mismatch probability of experimental images from 19% to 11% because global context vectors based on global shape information are induced to the SIFT vectors based local Information.

实验结果表明，由于在基于局部信息的SIFT向量中加入基于全局形状信息的全局向量，使得当特征点的尺度较小时，可以借助更大邻域范围内的信息对其进行描述，从而降低了由于局部信息相似而造成的误匹配的概率。

However, by giving different linearly independent vectors to the Gram-Schmidt process, the resulting class-label vectors will be different and so do the corresponding discriminants. That is, the solution of multi-class MSE is not unique and may not be the optimal.

但是，给予不同的线性独立向量，多类别最小平方误差区别会解出不同的类别标签向量，因而所求出的区别向量也会不同，此方法所求出的解可能并不是最佳解。

There is an exception to the rule of multiple vectors: Dangerous commands (like Erase All, Clear, Abandon Changes, and so on) should not have easy, parallel command vectors. Instead, they need to be protected within menus and dialog boxes (in keeping with our design principle from Chapter 10: Hide the ejector seat levers).

这个多种途径的规则有一个例外，危险命令（如全部删除、清除撤销及放弃更改等）不应该有容易且多种方式的命令途径；相反，我们需要在菜单和对话框中对这些命令加以保护（与第10章的设计原则保持一致，即隐藏弹射座椅控制杆）。

The algorithm is implemented by a three-stage iterative process. At the first stage, an iterative block matching algorithm is applied to generate more accurate initial disparity vectors, and at the second stage, an iterative polygon matching algorithm is employed to optimize the initial disparity vectors obtained at the first stage to minimize the error of certain triangulations. Finally at the third stage, the unreliable nodes are deleted.

该方法是一个三步迭代过程：首先利用迭代块匹配算法得到较精确的匹配结果；然后利用迭代多边形匹配算法对得到的匹配结果进行优化，使得一些三角形的预测误差最小；最后删除掉视差不可靠的节点。

In which, for the statistic that use the phase-space formed by position 1-linear vectors and momentum 1-linear vectors in 4D time-space and the mutual reactions among these particles can be dealt as elasticity collision, they are the usual de Broglie waves.

其中，对于4维时空位置1-线矢和动量1-线矢组成的&相宇&进行统计，当粒子间的相互作用可当作弹性碰撞时，它就是&德布洛意波&。

The number of support, vectors is decreased by 28%. Then, the structure of the Riemannian geometry is introduced in the input space, and using the Riemannian geometric modifies the kernel function of the classifier and gets less improved support vectors at the second training.

在第一次训练后产生的支持向量的基础上，将黎曼几何结构引入到输入空间，利用黎曼几何结构将分类器中的核函数进行修改，在第二次训练中再次减少了支持向量数目。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
