Total genomic DNA was extracted from four marine fishes (Verasper variegates, Cleisthenes herzensteini, Turbot Scophthalmus maximus, red seabream Pagrosomus major) using a proteinase K and phenol-chloroform procedure. Long mtDNA fragments were amplified by long and accurate PCR using primers designed based on the mtDNA sequenses of Thunnus thynnus thynnus, flounder Paralichthys olivaceus and other related fishes.

用蛋白酶k酚氯抽提法从圆斑星鲽、高眼蝶、大菱鲆和真鲷4种海水鱼的肌肉组织中提取基因组DNA，根据金枪鱼、牙鲆及相关鱼类的线粒体DNA序列保守片断设计出扩增引物，扩增从16SrRNA到ND4之间约9400bp的mtDNA长片段。

It consists of three components: the parameters estimating on-line; the calculating of closed-loop critical gain K and frequency ω; evaluating the PID parameters to enable the closed-loop syetem with the given phase margin.

该算法有三部分组成：在线参数估计；计算系统在比例控制下的闭环临界振荡频率ω和临界增益K；确定PID控制器参数使闭环系统具有给定的相位裕量。

Key words:3D model segmentation,cluster segmentation,3D point cloud,K-means cluster

提出采用K-means聚类分析方法对三维点云模型进行分割。

Several cluster validity measures have been proposed for confirming the optimal k value. However, the existing methods may not work well for the following two kinds of data sets: the data set containing cluster groups with different densities and the data set in which the cluster groups are extremely close to each other.

目前，已经提出了许多确定最佳k值的聚类有效性方法，但这些方法都不能很好地处理两种数据集：类密度不同的数据集和类间距比较小的数据集。

In light of the ConGraph, by adapting the concept of K-means and local search, an algorithm is devised to coarsely cluster objects for the purpose of efficiency.

接著，藉由ConGraph的协助，加上K-means和 local search 的概念，我们设计了一个有效率的粗略分群法。

The 35th Anniversary edition of the much-raved-about T3 gives players a choice of fiery-orange colored cocobolo (XXXV-T3-C) or rich, sparkling koa (XXXV-T3-K).

在备受妄言35周年纪念版，对T3让玩家火热的选择橙色cocobolo（第三十五科技- T3 - C）或丰富，波光粼粼的兴亚（第三十五科技- T3 - k）段。

In the first chapter,we discuss the problem of (Z_2)~k-actions with fixed point set of constant codimension.

在第一章中，我们对具有常余维数不动点集的(Z_2)~k作用进行了研究。

In Chapters 3 and 4, we study Dirac cohomology of unitary representations with a regular lambda-lowest K-typeμusingθ-stable data.

在第三和第四章，我们利用θ不变参数研究了最小K-型正则的酉表示的Dirac上同调。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
