查询词典 spheric segment

Since cross ratio is an invariant of the group of all Mbius transformations,and a Mbius transformation maps a circle into another circle, it is convenient to represent a segment of circular arc with a parametric complex rational function.

利用Mbius变换的保交比性质和保圆性质，给出了一种快速、简便地生成平面上的一段精确圆弧曲线的新方法。

First, it was to obtain two binary images from segmenting image by two thresholds. Second, erosion, opening and closing were done to the two images according to some knowledge of the shape and location of the objects in the image that we have already known. Last, the edge information from the image segmented by a high threshold was put into the image segmented by a low threshold. It is the way to segment and discern circular objects accurately from the complex image and can greatly improve the accuracy rate of discerning.

首先分别根据两个阈值进行分割得到两幅二值图像，然后根据目标是圆形以及其大致位置等先验知识分别对两幅图进行腐蚀，开启，闭合等数学形态学运算，将高阈值分割得到的图像中的边界信息叠加到低阈值分割得到的图像中，实现对复杂背景图像中圆形物体的准确分割与提取，解决了复杂背景图像中物体识别率低的问题。

We present two methods for generating a segment of circular arc by the vector valued continued fractions. Based on this method we construct a parametric rational arc spline that is GC〓 continuity. By adjusting the given tangent vector, this parametric rational arc spline also has convexity preserving property and monotonicity preserving property.

本文利用向量连分式给出了两种快速生成圆弧的新方法；在此基础上，本文还构造了一种GC〓连续的可调参数有理圆弧样条，在实际操作中，通过调整一侧端点的切向量，可使上述圆弧样条曲线保凸，保单调。

The company applied for registration of trademark in 2005 with the brand Zhixianglian. Zhixianglian people, in the infant stage of the company's development, combine the texts with graphics of globe, bridges and ribbons to encourage the staff to grow bigger, stronger and more sustainable. The bridge in the image was referenced with the circular segment of the Zhaozhou Bridge, implicating Zhixianglian people's admiration to the perfect quality of the ancient arch bridge that is still standing after 1,400 years. The ribbon is in golden color, which represents the values of credibility. All the elements in the logo design collectively give a connotation that reads "quality and credibility may pave the way for success."

二OO五年，"质相连"字号申请了国家商标注册，雏形时期的质相连人为了激励自己做大、做强、做久，将"质相连"字号与地球、桥梁、纽带组合成图形，图形中连接你我的桥梁参照赵州桥五孔形态，示意我们质相连人崇尚它一千四百年固在的完美品质，纽带为金色，代表诚信的价值，商标整体图形就是一段文字：她告诉人们只要把质量和诚信都做好的人，地球处处变通途。

Common Reflection Surface stack is a brand-new and special ZO imaging method, the theory of CRS stack stems from paraxial ray theory, the biggest difference between CRS stack and conventional ZO imaging method is that it consider a reflector R as a circular reflector segment Cr placed in the vinicity of reflector R, Cr can be seen as the second order approximation of the reflector. The CRS traveltime surface is the multi-coverage reflection response of the reflector mirror assigned to R.

共反射面元（CommonReflection Surface=CRS）叠加技术是一种全新的、特殊的零偏移距剖面成像方法，CRS迭加理论源于傍轴射线理论，它与普通的零偏移距剖面成像方法的最大区别是它认为地下反射层是由许多个小反射弧段互相叠合组成的，认为来自某反射点附近的一个邻域内的反射信息都可以对该反射点的成像作出贡献，因此对该反射点进行零偏移距成像时就应该聚焦更多的能量参与迭加。

A method of segment installation is applied to fix tube pole by tower crane and auto-crane, In order to control the dot which is signed on steel tube exterior project to corresponding dot on the ground, a theodolite is set in each direction, In order to ensure quality, the weld of interface of steel tube pole should be executed from middle of plane to circumambience

钢管柱通过塔式起重机和汽车吊采用分节安装的方法进行安装，安装时从两个方向各架设1台经纬仪以控制钢管柱外壁标记点的投影在地面作出的相应标记点上。

I see fit to the circumambience lesson establishes the 疑 queries, the around important a segment establishes the 疑 queries;Can also develop teacher's intense emotion according to the scene that establish, cause teachers and the students emotion the problem of the 鸣 to establish totally the 疑 query;Can also experience personally to establish according to the life the 疑 query.

我认为可以围绕课题设疑质疑、围绕重要句段设疑质疑；也可以根据创设的情景发挥教师激情，引起师生的情感共鸣的问题设疑质疑；还可以根据生活体验设疑质疑。
