方法首先利用算术变换进行非精确多项式电路优化，给出电路在不同精度界限下的实现，考虑电路的定点和浮点设计表示，然后应用分枝定界方法求解出最终的优化结构。

According to if there exists a one to one mapping between the two point sets to be matched, PPM can be divided into the case of complete matching and the case of incomplete matching. According to transformation type between the two point sets, PPM can be divided into the affine (including Euclidean and similarity) case and the projective case.

点模式匹配问题，根据待匹配的两个点模式是否存在一一对应的匹配关系，可分为完全匹配情形和不完全匹配情形；根据两个点模式之间满足的几何变换关系，可分为仿射变换（包括相似变换和欧氏变换）情形和射影变换情形。

This paper extends the solution methods for 2-D projective transformation matrix from 4 points corresponding to variety combinations of points and lines corresponding, such as 4 points, 4 lines, 1 point and 3 lines, 3 lines and 1 point, and 2 points and 2 lines, etc.

该文把求解2-D射影变换矩阵的方法从单纯的四点对应扩展到多种组合形式的四元素对应当中，如：4点、4线、3点1线、3线1点和2点2线等。

According to DTA and the microstructure information, it is obtained that the phase transformation begins from 430.1℃,the solidus point of the alloy is 614.4℃, and the liquidus point is 636.4℃.

通过对AZ31镁合金DTA曲线的分析和不同温度下金相组织的比较、分析，确定了该合金的相变起始温度为430.1℃，共晶温度为438.5℃，固相线温度为614.4℃，液相线温度为636.4℃。

The growth and nucleation rates of〓 cleavage face of YbYAB crystal are all very fast, because so many growth steps and growth centers were formed within only 2～3 second at the temperature near the saturate point. No spiral growth steps can be found, so growth mechanism is twodimensional nucleation. When the flux temperature increases for only 0.5℃ above the saturate point, the spiral melting holes are formed. The transformation from growth morphologies to melting morphologies is very sensitive to the temperature. When the temperature increases another 1℃, the spiral melting holes transform into two-dimensional nucleation melting holes.

YbYAB的〓解理面的生长及成核速度都非常快，在比饱和点低0.5～1℃的温度下，当生长2～3秒钟时，可以看到许多生长中心与生长台阶的形成，在较宽的台阶上还可以看到二维核的形成，没有看到螺旋中心，说明生长机理是二维成核生长；当温度比饱和点高0.5℃时，在〓解理面上形成螺旋状熔坑，这表明形貌由生长到熔化的转变与温度的关系是非常敏感的；当温度比饱和点高1.5℃时，螺旋状熔坑转变为二维成核状熔坑。

However, if the trigonal control point and datum transformation model do not exist, the result of base station single point absolute location can be used as reference coordinate, the measured result of which can be geo_referenced to remote sensing image using some tiepoints on the basis of the first result above.

例如 ，在利用遥感影像分类时，需要在外业获取用于监督分类的训练样地或是分类结果精度检验样地的大地坐标信息；在进行稀有树种区域分布特征调查时，希望能在遥感影像上标识出每个树的具体位置；发现某河段发生污染时，很可能需要将它的精确位置以线或面的形式显示在其它矢量或栅格图层上。

But my real point is this: Now Europe is at the point of transformation.

他们企盼一个多民族的欧洲而不是一个超级国家。

However, such a combination does not mean the traditional graphics or simply just copy the misappropriation, but rather to knowledge and understanding of the traditional graphics, and on this basis, gradually digging, change and transformation of the traditional graphics, and allow traditional graphics into the design of a new creative point and inspiration point, thus mapping out Hwan viable model of modern Chinese symbol.

然而，这样的组合并不意味着传统的图形或干脆只复制盗用，而是知识和传统图形的理解，并在此基础上，逐步挖掘，变化和改造传统图形，让传统图形成一个新的创意点和点的设计灵感，从而设计出焕现代中国的象征可行的模式。

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。
