在译介方面，本文回顾了我国亚氏著作和西方修辞学的研究和翻译，介绍了国内《修辞学》的两本中译本，并从六个方面对两个译本进行了比较。

After analyzing and processing the grating reticle image collected by CCD, the mapping coefficient can be accurately calculated from grid size to pixels. Comparing the fore-and-aft two grating reticle images after the worktable moved. Adopting phase difference ratio arithmetic based on Lissajous figures,the phase difference of two images will be figured out. The displacement of the worktable can be further calculated by the mapping coefficient.

调整光路使CCD获取清晰的光栅图像，对图像进行分析处理，计算出栅距与像素之间的映射关系，再对工作台移动前后的光栅图像进行对比，采用基于李萨如图的相位差比率算法获取它们的像素位置差，从而计算出工作台的实际运行位移。

First the math theory of machining simulation is studied, and the set structure of NC machining simulation system whose components, including time, input, output and so on, are defined. Hereby we set up the hierarchy structure, the logical structure, the static model and the dynamic model of simulation system. The construction method of sweep entity of cutter and rotation parts is researched, and their differential geometry invariants are calculated. NC code is unscrambled, and the recursion division arithmetic of time segment is put forward, which is the driven data of the movement or rotation parts. The CLDATA should be interference-free. To examine if there is interference between cutter flank and the work piece, an arithmetic that discussed the existence of intersecting curve between them is put forward. To examine if there is interference between two turrets, an arithmetic that discussed the existence of intersection set between two polygons is put forward.

首先研究加工过程仿真的数学基础，然后定义数控加工仿真系统的集合结构及时间集、输入集、输出集等概念，建立加工仿真的层次结构和逻辑结构，阐述双刀车削仿真系统的静态模型和动态模型建立方法，分析刀具扫描体和旋转部件扫描体的建立方法及其微分几何性质；研究NC代码解读技术和双刀加工时间段递归子分划技术，为驱动各仿真单元作数据准备；通过讨论后刀面和工件表面交线的存在性判断刀具后刀面与工件间是否干涉，通过求多边形的交集判断刀架与刀架是否干涉。

Experimental synchronous rotor internal mixer and two kinds of 55L synchronous rotor internal mixer, consulted a number of published articles at home and abroad, then, for the first time, formed four kinds of physical model and the corresponding mathematical model which related to the mixed stock between the mixing chamber side and the top of the rotor wing, to the mixed stock between the two rotors and to the mixed stock at the various temperatures of the mixing chamber. And from the character of model, the author gave the relevant analytic solutions and finite element approximation arithmetic solutions during the experimental process of the synchronous rotor internal mixer.

因此，本文作者在XM—1.7实验用同步转子密炼机和两种50L同步转子密炼机上进行了大量的实验，并参阅国内外已发表的文献和资料，首次建立了同步转子密炼机混炼过程中，胶料在转子棱峰与密炼室壁之间、胶料在两同步转子之间和密炼室中混炼胶温度变化的四种物理模型及其相应的数学模型，并根据所建模型的特点，分别给出了相应的解析解或有限元数值解。

The processor consists of two parts :Control unit and Arithmetic/logic unit , the two components are connected by a kind of electronic roadway called a bus.

该处理器包括两部分：控制单元和算术/逻辑单元，两个组成部分是通过一种被称为总线的电子线路连接起来。

Two independent pictures as evidence there is a lack of integrity by combining the two as evidence, because too many similar models. we can determine where the vehicle is the same, it's only a lack of evidence, law enforcement easily arouse controversy.

两者照片独立作为证据均缺乏完整性，两者结合作为证据，又因类似车型过多，我们无法判定是同一车辆，也就缺乏证据的唯一性，容易引起执法争议。

To check tort behavior, easy interesting website is made have " plan of attestation of intellectual property obligee ", remind the lawful sex that sells the home the goods that sells to net arsis to be in charge of, intellectual property obligee also can pass the regulation of attestation plan to be informed against to easy interest net after discovering the right is encroached, because this two the accused all already arrived to notice obligation reasonably, do not form the tort of pair of two accuser.
