P210bcr/abl plays a central role in the pathophysiology of CML. The purpose of this study was to construct a cell line model that bcr/abl expression can be regulated by Tetoff inducingexpressionsystem. The fulllength b3a2 bcr/abl cDNA was subcloned into the pTRE2hyg expression vector to construct the pT2P210 plasmid.

Vector equations is one of non-linearity equations, and we can solve it by inherit arithmetic or homotopy arithmetic.

矢量方程组属于非线性方程组，可以采用遗传算法或同伦算法进行求解。

The traditional classification methods only use one single classifier, which may lead to onesidedness, low accuracy, and that the samples nearby the Support Vector Machine hyperplanes are more easily misclassified. To solve these problems, the multifeature fusion method based on SVM and KNearest Neighbor classifiers was presented in this paper.

针对传统分类方法只采用一种分类器而存在的片面性，分类精度不高，以及支持向量机分类超平面附近点易错分的问题，提出了基于支持向量机和k近邻的多特征融合方法。

This algorithm uses binary tree to construct the multiclass frame by decomposing the problem into three 2class classification problems, then uses Support Vector Machine optimizing the three hyperplanes.

该算法首先使用二叉树进行多类决策，将原始分类数据分解成3个二类分类问题，然后利用SVM进行二类分类，使3个分类超平面得到优化。

The combinations, and movements, of these masses with gravitational, centrifugal and orbital velocity vector forces, create what we call the equatorial bulge, and thus, the axis of figure.

具有重力，离心力和轨道速度的矢量力的质量结合与运动，引起了我们所谓的赤道区鼓起，而就是形状轴。

Objective To construct the eukaryotic expression vector for pathogenic gene MYOC of primary open angle glaucoma and express in COS-7 cells.

目的 构建原发性开角型青光眼致病基因MYOC的真核表达质粒，并在COS-7细胞中表达MYOC蛋白。

Though Nom Anor as a Yuuzhan Vong infiltrator was created for The New Jedi Order series of novels that started with Vector Prime, comic readers first got a brief, shadowy glimpse of the character in Crimson Empire II, where the character's motives and background remain largely a mystery.

虽然作为一个遇战疯族渗透者，农·阿诺是为以《主向量》为首的《新绝地武士团》系列小说创作的，但漫画读者在《血红帝国 II》里就能短暂模糊地瞥见这个角色，但他在那里面的动机和背景基本是一个谜。

Bases on the XML Key, the algorithm firstly dealt with XML structure to vector matrix, then used project frequent pattern tree to optimize the XML structure through dissociating, uniting, updating and canceling to satisfy the conciseness of the XML structure and query multiversity.

该算法以XML键为基础，利用向量矩阵处理方法、投影频繁模式树实现XML结构的分裂、合并、更改与取消等操作，同时讨论XML键向量矩阵频繁项集的划分规则及相应启发式策略与支持度阈值。

Methods: One-step trizol had used to get the total RNA of the four animal brain, then PEGS000 to purify the small RNA from the total RNA, after the ligation ofpoly on the 3\' and the adaptor on the 5\', the oligo primer will be used to reverse translation the small RNA, and then used the specific primers to amplification the small RNA sequences. After the gel purition recovery, the small RNA will be ligated to the T-vector, and be transformed to the TOP 10 E. coli, at last, we picked up the masc. clones for sequencing.

通过Trizol一步法提取四种动物脑中的总RNA，接着用PEG纯化其中的小分子RNA，再经过poly连尾反应在小RNA的3'端连接上一段poly，然后在5'端连上adaptor，用Oligoprimer将连接好的小RNA进行反转录，用根据adaptor和Oligoprimer设计的引物来扩增小RNA，扩增后的小RNA进行胶回收后连接到T载体上，转化TOP10大肠杆菌后挑取阳性克隆进行测序，得到的序列再经过生物信息学的分析后确定是否为miRNA。

Objective:To explore the feasibility of laparoscopy in diagnosing and treating of abdominal diseases.
