向性

By means of the plus or minus characteristic, not only simplified the position judgment between the point and the directed line segment, reduced the algorithm complexity, more eliminated drastically various unstable factors.

借助于正负性，不仅简化了点与有向线段的位置判断，降低了算法复杂性，是彻底消除了各种不稳定的因素。

For improving the algorithm, the text started with analyzing the plus or minus characteristic of a straight line, further described roundly various mutual positions relation between the point and the directed line segment and the corresponding disposing process.

为改进算法，首先从分析直线的正负性入手，进一步全面描述了点与有向线段的各种相互位置关系及相应的处理步骤。

The thesis puts forward intensive definitions of three types of relations and their consistency. By building the corresponding model based on graph theory, it studies the consistency property of relations, and brings forward three static consistency validation methods with the assistance of graphic connectivity, directed path, accessibility et al.

论文对这三种类型的关系及其一致性进行了详细定义和研究，通过建立相应的图论模型，借助于图的连通性、有向路、可达性等，研究了各种关系的一致性性质，提出了三种静态一致性的检验方法。

The data analysis shows that: 1 different texture parameters have a clear scattered distribution, 2 the main direction of texture is the direction represented by the maximum parameter of Gauss-MRF parameters, and 3 for those samples basing the same main direction, the finer the texture is, the greater the corresponding parameter is, and the smaller the other parameters are; and the higher the order of Gauss-MRF is, the more clearly the texture is described.

数据分析表明，各不同纹理特征参数之间具有明显的分布性；Gauss-MRF参数值最大的参数所表示的纹理集聚为向为纹理的主方向；对于纹理主方向相同的样本，纹理越细致，其相应参数越大，而其他参数越小；Gauss-MRF阶数越高，纹理描述越细致：在2阶Gauss-MRF模型情况下，弦切纹理的B1参数大于径切纹理的B1；弦切纹理的B2、B3、B4分别小于径切纹理的B2、B3、B4。

The right of divulgation in the internet, means that an author has the right to determinate whether to issue his works publicly by means of the internet, and also may comprehend one kind of static fight that the right man owns by law,but the fight of transmission in the internet is a right that the author and related right men carl enjoy with cable or wireless means to supply their works to the public,causes the public to obtain the works in the fixed time and site.such reflection is the actual condition the authors had achieved the right of divulgation.

网络发表权是指作者决定是否将其作品通过网络公之于众的权利，所反映的是一种待实现状态，也可以理解为是权利人依法享有的一种静态性权利；而网络传输权是指著作权及相关权利人享有以有线或者无线方式向公众提供作品，使公众可以在其个人选定的时间和地点获得作品的权利，其反映的是作者实现发表权的现实状态。

Japan's reflex response has been to draw closer to the US.

日本对此的反射性反应，迄今一直是向美国靠拢。

Driving system consists of gearwheel box, universal shaft couplings and arc-gear synchronous belt .

传动系统采用齿轮箱、万向轴联轴器、圆弧齿同步带相结合型式，传动构件安装在底板，避震性好。

Considering the particularity of the road network and the demand of the shortest path algorithm for the road network information, a new method of representation and storage of the road network to enhance the real-timeness of the shortest path algorithm was proposed based on the basic idea of the dual graph representation to improve the forward star structure.

考虑实际道路网络的特殊性以及最短路径算法对路网信息的要求，运用对偶图法的基本思想对前向关联边结构进行了改进，提出了一种能够提高路径优化算法实时性的路网表达方法与数据存储结构，并用Dijkstra和A*最短路径算法进行了验证。

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.
