A curvature based method for controlling iteration step is further proposed by projecting the given point onto the curvature circle of the normal transversal at the initial point.

仿真结果表明，该算法具有良好的收敛性、鲁棒性以及精确性。正交投影的概念最早出现在文献[1]中。所谓正交，就是在曲面上找到一点，使得该点与空间某一给定点的连线与曲面在该点处的切平面是垂直的。

And the matching point pairs are obtained by comparing the Euclidean distance of the Zernike moments,which are computed around a circular neighborhood centered at the feature point.Then the transform parameters are computed through the correct mapping model.Finally,the weighed average method is used to achieve image mosaic.

该算法利用曲率尺度空间角点检测法提取特征点，通过比较各特征点圆形邻域Zernike矩的欧式距离得到匹配点对，然后利用正确的映射模型计算出变换参数，最后采用加权平均法得到图像的拼接结果。

Once the intersection point is found, all that is left is to determine the color and normal at the point of intersection.

一旦找到了交点，接下来就需要确定交点的法向和颜色。

The integrated circuit also has at least a second current feeding circuit having an output connected to the feeding point for the first current feeding circuit, a feeding point connectable to a feeding voltage, and a control input for controlling the programming of the NPN-transistor.

所述集成电路还包括至少一第二电流馈电电路，所述第二电流馈电电路具有一连接至所述第一电流馈电电路的所述馈电点的输出端、一可连接至一馈电电压的馈电点及一用于控制对所述NPN晶体管进行所述编程的控制输入端。

As to the remaining parameters, two methods are developed: first, accepting that the projection function complies with a circular function within at least a part of a given field of view, constrained by the obtained object-to-image radial mapping and a constant focal length, the best-fitting point of the optical origin is tested along the optical axis; secondly, referring to the postulation of the exclusively bilateral mapping between an imaged point and its scenic sight ray, a measuring technique is developed to survey the world coordinates which will fabricate a projecting path to the imaged points located on the imageable region of the image plane in order to directly model the projection geometries involved.

而针对其余参数本文提出两种解题方法：其一是根据『在「部分视野角范围」内，鱼眼相机的投射模型符合一典型的「圆形函数」』以标靶实体与其影像尺寸为限制条件，测试光学轴上的最佳视觉参考点、鉴定最适当的投射模型、焦距、及有效的视野角度范围。其二是根据『一视野线排他性地与对应「呈影点」一一映射』参考一呈影点来搜寻空间中对应视野线的绝对座标后，据以演绎相机内部影像形成的模型。

Faraday's law is that when the flux in the conductor loop changes, it produces electromotive force in the conductor loop, and obeys to contour integral law , Maxwell Curl Theory is that when the magnetic intensity of a certain point in ether space changes, there produces electric field at that point in ether space, which is the field mutual production theory of "electric field produces magnetic field and magnetic field produces electric field" in the free space which everybody is familiar with, and it obeys differential law , Lorentz magnetic force is that when metal electrons cut magnetic lines, metal electrons forced by move along the conductor to form inductive current, in fact, it doesn't matter whether coil moves or magnet moves, only if there exists relative motion between magnetic field and conductor, metal electrons must cut magnetic lines, which is,"coil stills while magnet moves to the left" and "magnet stills while coil moves to the right" these two situations are the same, which both belong to metal electrons having cut magnetic lines.

法拉第定律指导体环路里的磁通量发生变化时，在导体环路上产生电动势，而且服从围线积分律；麦克斯韦旋度理论指以太空间某点的磁场强度发生变化时，在以太空间的该点产生电场，即大家熟知的自由空间里"电场生磁场与磁场生电场"之互生场理论，而且服从微分律；洛伦兹磁力指金属电子切割磁力线时，金属电子受力沿着导体漂移而形成感应电流，其实，无论线圈运动或是磁铁运动，只要磁场与导体存在相对运动，则金属电子必然切割磁力线，即，"线圈静止而磁铁向左运动"与"磁铁静止而线圈向右运动"这两种情况是一样的，都属于金属电子切割了磁力线。

The direction of search starting from an extreme point is a convex combination of all descent directions along the edges at the point.

n己！。坐犷、J砂二二1 求解线性规划的起作用集法是单纯形法的一种变型〔'，2〕。

While the second and third line brands in the sales policy of flexibility and protection dealers usually do better, they and other big cities in the provincial capital is a city of decorative materials for a point or a point of a district sales division for the Second , three-city business strategy based on two different cities by the general agents, agents for the distribution level, there are many companies now control channel at the county level has been sinking into the city, a county established a sole agent to ensure that agents, the interests of dealers.

而二三线品牌在销售政策的灵活性和对经销商的保护等方面通常都做得比较好，他们在省会等大城市是一个装饰材料城设一个点或是一个区划分一个点销售，对于二、三级城市则根据企业的战略不同可由二级城市设总代理商、一级代理来进行分销，也有不少企业如今对渠道的掌控已经下沉到县级城市，一个县城设一家独家代理，以保证代理商、经销商的利益。

The next time you feel the need to point your finger in blame - whether it be at the car manufacturers in Detroit, your partner, your parents or the latest in a long line of crooked politicians - make a point of being aware how you feel.

结论下次打算指责别人的时候——无论对方是底特律汽车制造商、你的合伙人、父母、还是众多不诚实政客中的新闻人物——要重视了解自己的感受。

In that night and the night, Qian all over the place with my thoughts, perhaps one day will cross at some point into a point!

在那个夜与这个夜，钱学森与我的思绪满天飞，也许某天会在某一点交叉成一点！

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。
