查询词典 Point Four

Furthermore,we present the method for designing quadratic Bezier developable surface:give four corner points of developable surface and two free designing parameters,the other two control vertexes are on the line connecting the linear interpolation point between the first two control vertexes and the linear interpolation point between the last two control vertexes,and they are the linear interpolation points between these two linear interpolation points respectively,namely,these four linear interpolation points are colinear.

提出了二次Bézier可展曲面的设计方法：给定可展曲面的4个角点a0、b0、a2、b2和两个自由设计参数？姿、？滋，则待求的2个控制顶点a1、b1是在前2个控制顶点a0、b0的线性插值点a*与后2个控制顶点a2、b2的线性插值点b*的连线上，并且也是a*、b*这2个线性插值点的线性插值，即这4点a*、a1、b1、b*共线。

In addition, spot color screen angle in software will normally be preset to 45 ° c (45-degree, is considered the most comfortable utilizinghuman-aware, so that the angle of the dot is arranged in horizontal and vertical lines to equal rotation, you can reduce the human ability to mesh point detection), if a Duotone image or data file into the existing business card printing and membership card making four color black%(General in the four-colour screen business card printing and membership card-making Black mesh point-and-drop, in a 45-degree is 0 degrees for yellow, magenta to 15 degrees, 75 degrees), and spot color, or with more than two spot colors, the color screen is to a 45-degree output, so use the spot color, while if it is possible with other screening to overprint colors, you must open the output color separation software color settings or the print dialog box, on the halftone angles to make modifications.

另外，专色的增网角量在软件洋凡是城市预撤为45量（45量均被觉得是人眼感知最安适的角量，让网不背摆列在与程量和垂直线不败不等角量的标的目的上可以裁减人眼差网不背的发现本领），若是一个单色调影像或是数据文件洋既有制卡和会员卡制息四色暗不败外（凡是在四色增网制卡和会员卡制息洋，不兵暗网不背不收在45量，黄为0量、品赤为15 量、青为75量），又有专色，或者是有两个以上专色，则在分色增网时城市以45量输入，所以在差专色搁置浅网时，如果有不定与其他增网颜色有叠印，则务必在分色输入时开放软件颜色撤定或打印撤定的差话框，差专色增网角量举动编削。

The critical point means such a state that all the differences between gas and liquid disappear completely,being a most important parameter of dividing the types of fluid and being widely verified in both theory and practice.Currently,four methods of determining critical point are summarized as follows:①laboratory measurement through examining critical opalescence or recording the bubble point and dew point curves;②empiric relation;③calculation of the bubble point and dew point curves by PVT software;and ④ direct calculation according to thermodynamic theories.

随后对临界点进行确定，临界点是气液一切性质差异均消失的状态，是区分流体类型最重要的参数，并得到了理论和工程应用的广泛验证，目前确定临界点大致有四种方法：①实验测定，通过观察临界乳光现象或记录流体的泡点和露点线；②经验关系式；③通过PVT软件计算流体的泡点和露点线；④利用热力学理论直接计算。

The surface of conventional engineering part is composed of simple analytical surfaces and four-boundary ruled surface primarily. Therefore a point cloud segmentation method based on those feature surfaces is proposed. Several algorithms to identify the simple analytical surface feature are investigated and discussed. The theory of fitting scattered point to B－Spline and Bézier surfaces is introduced and a fitting method based on four boundary and point set is also discussed. Moreover, anew method to recover the fix-radius rolling ball blend is proposed and discussed in detail.
