查询词典 vectors

The method firstly organizes support vectors in clusters in feature space, and then,it finds the pre-images of the cluster centroids in feature space to construct a reduced vector set.

此方法首先在特征空间中对支持向量进行聚类，然后寻找特征空间中的聚类中心在输入空间中的原像以形成约简向量集。

There are many situations where observed data are in the form of direction cosines or vectors but with an unknown positive scalar so that only the direction is known.

实际中常有这样的情形，当我们观察到的数据是以方向的形式或者以向量的形式给出但却具有未知的度量单位，因而只知道它们的方向，这时我们观察到的就是球面数据。

Taking gauss curvatures and normal vectors as random variables, Lorentz Curve was extended to 3D Lorentz Surface.

以高斯曲率和法向量为随机变量，将洛伦兹曲线扩展为三维，得到洛伦兹曲面。

Finally, it distills the vectors of low-level features, and transforms the matching between two images to the matching between two blocks.

最后，提取图像数据块的底层视觉特征矢量，将两幅图像之间的匹配转换成图像块之间的匹配。

The analysis of wind vectors from automatic surface observations shows that the mesoscale convergence line between the northerlies and the easterlies in lower troposphere is very important to the torrential rain , which determines the locations and timings of the torrential rain .

地面自动站以及加密站风场资料分析指出，低空偏北风与偏东风之间的中尺度辐合线对暴雨发生有重要作用，其出现的时间和位置决定了中尺度暴雨天气的发生时间和位置。

Eukaryon expression vectors containing humanbcl-2 and bax cDNA were respectively transfected into HCC-9204 cells,HCC cellsthat express Bax stably and highly were established,and an HCC cell strain thatexpress Bcl-2 at a 100% positive rate was obtained by cloning.

用脂质体介导的基因转染法分别将含有人bcl-2和bax cDNA的真核表达载体转染到HCC-9204细胞中，建立稳定高表达Bax的肝癌细胞，并用克隆化的方法建立100％稳定表达Bcl-2的肝癌细胞株。

The shRNA eukaryon expression plasmid vectors targeting rat Pik3cb were constructed using VSMC-specific SM22α promoter.

采用血管平滑肌细胞特异性SM22α启动子构建靶向大鼠Pik3cb基因的干扰RNA真核表达载体，既可抑制新生内膜增生，又可防治血栓的形成。

We calculate the eigen decay rate andmixture of the excitons with different vave vectors.

求出了各个本征衰率和不同波矢激子的混合。

At first, the initial values of motion vectors of blocks in the face area can be found by calculating the 2D parameters of general head motion. With the initial values, the range of further search in motion estimation can be reduced, and the results are consistent with the actual motion.

首先提出一种通过求出脸部区的二维全局运动参数来求各像块的运动矢量初值的方法，在得到各像块的运动矢量初值后，搜索范围可以很小，搜索到的精确的运动矢量更符合真实运动。

The parameter values can be represented as a contour plot, as isolines, as vectors, or in a combination e.g.

参数值能被代表作为一个轮廓图作为isolines 作为矢量，，或者在一种结合 e.g。

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。
