其次，本文在研究了包括Rocchio's 算法、Na？

After the analysis of the algorithms model of MPEG-2 AAC, the thesis optimizes some blocks with great computation of Psychoacoustic Model, Filter banks and Quantization coding, etc. It omits some function blocks which have much computation and avail little to the gain of coding, for example, prediction in time domain, TNS, etc. It also adopts some fast algorithms to reconstruct some model for the reason of real time characteristic.

在对 MPEG-2 AAC算法模型进行分析之后，对心理声学模型，滤波器组和量化编码模块等计算量较大的模块进行优化，同时也省略了部分运算量大但对编码效果增益不明显的几个模块，如时域预测和 TNS 等，并使用了一些快速计算技术对算法模型进行实时化改造。

This paper concludes the clustering algorithms used in data mining and assorts them into 7 classes. Seven types of algorithms are summarized and their performances are analyzed here.

And the attributes, classing and applying matter of digital watermarking technology is presented in a nutshell. Some typical algorithms and performance is analyzed. Then three algorithms based on DCT are carried out.

然后在MATLAB环境中实现了三种基于DCT的数字水印算法，并通过各种常见的图像处理、压缩、剪切和加噪等各种攻击实验验证了这三种算法所生成水印的性能。

We introduce several typical clutters elimination algorithms and contrast them. We eliminate clutters using LMS algorithms.

介绍了几种典型的杂波抑制算法，对此几种方法进行了比较，并用LMS算法进行抑制。

Based on the analysis of noise level and image edge patterns of the image, the mode decision and motion estimation algorithms proposed have the adaptability to input video. Without decreasing compression performance significantly, the complexity of a video encoder with the two algorithms deceases dramatically.

所以，最后，本文提出了一种具有抗噪声干扰能力的运动匹配准则：自适应超级块扩展匹配准则，接着还对一种性能较优的快速运动估计算法进行噪声自适应性扩展设计。

The basic idea of matching algorithms is: decompounding the subscription graph pattern and event graph into a series of arcs which are the basic units for matching algorithms.

我们的匹配算法的根本思想是将订阅图模式和事件图分解为一系列弧的集合，以弧为单位进行匹配。

This paper summarizes all kinds of the bandwidth smoothing algorithms for prerecorded VBR video ,compares the performances of these algorithms ,induces and formalizes these smoothing models,and gives the generalization description of them.

文章综述了存储 VBR视频带宽平滑的各种算法，比较了这些算法的各自特点，归纳、形式化了这些算法模型的更一般化表示。

The behaviour models including family, enterprise, landowner and government are built. The behaviour of economic main body is formulized. The algorithms of expected indirect function of maximal expected utility on behalf of family, enterprise and landowner in daily life are proposed. The algorithms of maximal expected utility while family and enterprise location choice action are proposed.

建立了家庭、企业、土地所有者与政府的行为模型，将各主体的行为公式化，提出了日常生活中代表家庭、企业及土地所有者最大期望效用水平的期望间接效用函数的计算方法；家庭、企业在土地选择行为中的最大期望效用值即满足度函数的计算方法。

Hybridizing intelligent approach(Genetic algorithms and tabu Search) was applied in the model to improve the weaken local search ability of Genetic algorithms.

为解决该问题，提出了一种将遗传算法和禁忌搜索算法进行结合的智能搜索算法以加强遗传算法局部搜索能力。

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。
