查询词典 vector

To obtain the unknown intermediate vector function needs to solve a Fredholm integral equation of the first kind, the solution of which can only be determined with a difference of a vector proportional to the normal of the boundary and its integration on the boundary must zero.

可是要求出该积分表达式中待定的边界上的向量密度函数要导致求解第一类Fredholm 积分方程。

After finding the free slots to place the vector, the transition vector must be recalculated as follows. Assuming the new place begins at b , the procedure for the relocation is

在找到空闲的位置来放这个向量，转移向量必须重新如下计算，假设新的位置开始于 b ，重新分配的过程如下

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。

It is the fact that three methionines distributed in the Hsp16.3 will begradually oxidated, in vitro, by hydrogen peroxide(H2O2). When the hsp16. 3 gene was cloned with pMV261 plasmid vector and transfected into Mycobacterium smegmatis, we found that the ability of anti-H2O2 will be decreased greatly among the strains of M. smeg. containing pMV261-hspl6. 3 while compared with the control strains of M. smeg. containing free plasmid vector. But we found that the ability of anti-H2O2 will be increased greatly among the strains of M. smeg. containing pMV261-38kDa while compared with the same control.

尽管Hsp16.3中有三个甲硫氨酸在体外能被过氧化氢(H_2O_2)逐一氧化，我们将Hsp16.3基因克隆到pMV261质粒上，并转染到耻垢分枝杆菌中发现，转染了pMV261-16.3的耻垢分枝杆菌抗过氧化氢的能力大大下降，而对照含pMV261-38kDa的耻垢分枝杆菌抗过氧化氢的能力却有明显的增强，据此，我们认为，Hsp16.3在细胞内可能不具有抗过氧化氢的能力。

Based on the concept of space vector, an open loop detecting method for the fundamental negative and positive sequence components as well as the harmonic components is developed, which combining the conventional detecting method based on filters and the concept of space vector. This method can overcome the defaults of the conventional detecting method, and can meet the requirement of the asymmetrical control of HVDC-VSC.

运用自适应干扰对消原理和空间矢量的概念，提出了一种基波正序分量、基波负序分量及谐波分量的自适应检测方法，并进行了详细的理论分析，为研究HVDC-VSC的不对称运行控制奠定了基础。

Lividans. Using pIJ903 bearing tsr gene as a vector, the two furthermost fragments of the cluster, 4. 0kb and 1. 5kb in size respectively, were inserted into it. To facilitate the detection of gene replacement, apr gene was placed in the middle of the two inserts. OriT from E coli plasmid RK2 was also incoporated into the vector, therefore, pIJ903 derivatives can be mobilized from E.

在具有硫链丝菌素抗性基因的pIJ903的单—BamHI位点，同向插入了FR-008生物合成基因簇两个最远端的4.0kb和1.5kb片段，并在二者之间插入了可在链霉菌FR-008和变铅青链霉菌中表达的阿泊拉霉素抗性基因，同时也插入了有助于将质粒引入链霉菌的oriT片段，从而构建出了置换整个基因簇的基因置换质粒pHZ691。

It is one of the important characters of the grey system theory to utilize grey generation modeling. The basis structures of generating space in AGO and in IAGO are respectively obtained by the mathematical research of r-AGO series and r-IAGO series. The results are the following: the coherent and direct expression of the generating basis vector in AGO and r-AGO, the relation expression between two r-AGO series and two r-IAGO series, the relation among generating basis vector, generating series and moving operator.

利用灰色生成建模是灰色系统理论的重要特点之一，通过对r次生成序列（包含r-AGO序列和r-IAGO序列）的数学研究，得到了AGO生成空间和IAGO生成空间的基本结构：AGO和r-AGO生成基向量的统一的直观表达式、任意两个r-AGO序列间与任意两个r-IAGO序列间的关系式、生成基向量生成序列与移动算子间的关系。

To improve the training speed performance of large-scale support vector machine, a fast algorithm is proposed by exploiting the geometric distribution of support vector in feature space.

如何降低支持向量机海量训练样本的数目，是提高算法速度的关键。

For the head-teacher of the class said that I had seriously broken the school rules,which led me to a three-day suspend class.

为什么呢？因为我的班主任说我严重的违反了校规，于是让我停课三天。

Many of them believe that the conversion of thousands of working-class folk in England spared that nation from the mass carnage and the tyranny that came with the revolution in France.

他们之中有许多人相信，在英国数以千计的劳工阶级之悔改信主使英国免於遭受如法国大革命所造成的大屠杀和专制暴政。
