We happened to walk by Solvang Antique Center bell tower right at noon; the carillon tolled twelve, followed by a cheerful tune.

正午时刚好逛到骨董中心，中心的钟楼庄严地敲了十二声，接下来又响亮地奏出耳熟能详的曲子。

In section 5, separation of di-peptides with two chiral centers using cyclodextrin modified micellar electrokinetic chromatography was investigated.

论文的第五章采用环糊精修饰的胶束电动色谱手性拆分了具有两个手性中心的二肽对映体，并应用于模拟人血清样品中这些二肽对映体的分析。

A new multiclass SVM algorithm based on binary tree was introduced on E-mail filtering. It could convert multiclass problem to binary classification by constructing binary tree. The idea of clustering first and classification later was adopted, and the largest similarity between testing sample and sub-category center and the separation measure of subcategories were calculated, in oder to construct the optimal class hyperplane of decisionmaking nodes.

提出一种基于二叉树的多分类SVM算法用于电子邮件的分类与过滤，通过构建二叉树将多分类转化为二值分类，算法采用先聚类再分类的思想，计算测试样本与子类中心的最大相似度和子类间的分离度，以构造决策节点的最优分类超平面。

The endocyclic Sn atoms exist in a distorted triginal bipyramidal geometry with the coordination number of 5. The exocyclic Sn atoms form 6 significant bonds and exist in a distorted octahedron geometry.

化合物12的X衍射单晶测定表明，化合物是以Sn2O2四元环为中心的中心对称二聚体结构、内环锡为5配位的畸变三角双锥结构、外环锡为6配位的畸变八面体结构。

An efficient central ellipse algorithm for estimating the echo peak positions of ultrasonic sampling was presented to find the accurate receive time of echo by searching the peak of energy bursts, which is base on the theories of energy centrobaric correction method and least square method in the ultrasonic ranging system.

基于能量重心校正法和最小二乘法的原理，提出了一种改进型椭圆中心超声回波寻峰算法：通过曲线拟合搜索椭圆中心点，即回波信号能量集中点，进而找到回波信号的峰值点。

ELMC accomplishes the second distributed power of Aircraft.ELMC incepts the information from PSP through MIL-STD-1553B bus, monitors and controls the second bus of the aircrafts electrical system and the Solid Status Power Controlers in the same time, then sends all the information to the PSP.

电气负载管理中心主要完成飞机的二次配电，它通过MIL-STD-1553B总线接收电源系统处理机的控制信息，对配电中心的分布式汇流条以及固态功率控制器进行检测与控制，并负责把处理完的信息通过1553B总线传送给PSP。

Macrocycle with two aryl oxdiazolesThe structure of this type of macrocyclic compounds with two aryloxdiazoles attached to the nitrogen atom of amino acids is different fromthat of the above compounds.

三。含双噁二唑的大环：在这类分子中两个芳基噁二唑通过氨基酸的氮原子连接成环，而将手性中心和羧基端放于环外，这可提高分子的络合性能。

The news of the trial's start made headlines in the country, and people were feeling "very numb," said Youk Chhang, head of the Documentation Center of Cambodia, where about 20 members of the public had gathered to watch the televised proceedings.

虽然审判开始的消息成为该国的报头新闻，然而人们对此的反应却相当麻木。柬埔寨档案中心的负责人Youk Chhang指出，。在该中心，大约有二十名民众在观看审判的现场直播。

The dynamic constraints on the system are second-order nonholonomic constraints. It is assumed that the rigid bodies are hinged at the center of percussion. By the translational acceleration inputs at one of the rigid bodies, the system has two different kinds of rotation around the center of percussion.

该系统的动力学约束是二阶非完整的，通过给定其中一个刚体的加速度输入，并假设被动关节安装在刚体撞击中心处，系统可以产生两种不同形式的绕撞击中心的转动。

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。
