查询词典 vector function

The following results were achieved: 1 The 2005 greenbelt status quo map in Fuzhou was got by the combining use of processing remote sensing image and field investigation. Then the map was changed into the type of vector. The patch area, perimeter and quantity were calculated by the inner function of AUTOCAD.

研究结果如下：(1)运用遥感影像处理和外业调查相结合的方法，获得福州市2005年的绿地现状图，采用AUTOCAD软件进行矢量化，并通过该软件自带的功能计算绿地斑块的面积、周长以及统计斑块的数量。

Tension Control of the book's introduction, from the tension control Uncoiler principle, characteristics, classification, function and implementation are described; vector transformation from the basic principles of control, inverter control technology boards T400 model and outlines the aspects of how to control the tension the problem; In addition to the tension control roller load balancing and analysis were summarized, the principle of load balancing, sorting and implementation.

有关开卷机张力控制的介绍，从开卷机张力控制的原理、特点、分类、作用及实现进行了阐述；从矢量变换控制的基本原理、变频器的控制模式及T400工艺板方面概括了张力如何控制的问题；另外对张力辊的负荷平衡控制进行了总结和分析，有关负荷平衡的原理、分类和实现。

We introduce an accurate online-learning support vector machine algorithm, including incremental and decremental algorithm, which efficiently updates a trained regression function whenever a sample is added to or removed from the training set.

本文充分利用支撑向量机解的稀疏性并结合KKT条件，当向训练样本集中添加新样本时，调用&递增&算法修改原有回归函数来得到新回归函数；当从训练样本集中剔除旧样本时，调用&递减&算法修改原有回归函数得到新回归函数，即在线学习方法。

This method first maps training data into a high dimensional feature space through kernel function concept in Support Vector Machine and constructs orthogonal space in the feature space. Then it maps the data from feature space into the orthogonal space and computes Fisher criterion based global orthogonal discriminants.

首先应用支持向量机中核函数的概念，将样本隐式地映射到特征空间，然后构造特征空间的正交空间，再将特征空间样本映射到特征空间的正交空间，求解基于Fisher的全局正交鉴别矢量集。

In order to study the expression, subcellular distribution and the function of NS2 protein, the coding region of NS2 was amplified from the hindgut tissue of cockroaches infected with PfDNV by RT-PCR and then the recombinant prokaryotic expression vector pET28a-NS2 was constructed. The recombinant plasmid was transformed into E. coli BL21 (DE3) to express the 6×His fusion protein in the bacteria.

为了对该基因进行深入的功能研究，从感染了黑胸大蠊浓核病毒的蟑螂的后肠组织中通过RT-PCR得到ns2基因编码序列，将其构建于原核表达载体pET-28a，转化大肠杆菌BL21(DE3)获得融合表达产物。

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。
