After comparing Bayes,K neighbors,neural network and support vector machine these four typical text categorization devices,the author builds a text categorization system using support vector machine.

在比较了贝叶斯、K近邻、神经网络和支持向量机四种典型的文本分类器的基础上，采用支持向量机分类器搭建了一个文本分类试验系统。

The thermodynamic state vector, Sk, which comprises four vector components, i.e., the sequence number, the position and the local solute concentrations in both SCms and SCses, is introduced to describe the local thermodynamic path and the macroscopical thermodynamic path.

引入由溶质微元的序号集合、溶质微元的位置矢量、固定相溶质浓度矢量和流动相溶质浓度矢量组成的热力学状态矢量Sk，并用其来描述色谱过程的局域热力学路径和宏观热力学路径。

Instead of using a single term vector as event representation, the terms into four semantic classes are split(names, temporal expressions, spatial terms and contents) according to the semantic diffirence of them, form four vector spaces, and process and weigh the classes separately.

该方法没有使用传统向量空间模型中的单个向量，而是按照语义将特征词划分为4个组（人物，时间，地点，内容）并形成4个向量空间，每个空间进行独立的权重计算和相似度计算。

The foundations of support vector machines are introduced. Four mathematics models of support vector classifications including linearly hard margin SVM, linearly soft margin SVM, non- linearly hard margin SVM and non-linearly soft margin SVM are discussed.

摘 要：介绍了支持向量机的基本思想，依据是否引入核函数，是否具有惩罚因子，支持向量分类算法被分为线性分界面硬间隔、线性分界面软间隔、非线性分界面硬间隔和非线性分界面软间隔四类，并讨论了它们的数学模型。

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。

Many will continue to choose to live in duality and in conflict.

许多人将继续选择活在二元对立性和冲突中。
