查询词典 regular polygon

The intermediate frequency elbow piece formation technology basic technological process is: First welds a lateral section is the polygon many leng link shell or both sides seal many leng fan-shaped shells, after the interior flushes the full pressure medium, the serve intrinsic pressure, under the intrinsic pressure function the lateral section by the polygon gradually changes a full circle, ends in a circular link shell.

中频弯管成型技术基本工艺过程是：首先焊接一个横截面为多边形的多棱环壳或两端封闭的多棱扇形壳，内部冲满压力介质后，施以内压，在内压作用下横截面由多边形逐渐变成圆，最终成为一个圆形环壳。

At first monotone chain of polygon is spaned in the new algorithm. Second, the nonregular vertices are sorted by Y-coordinate. At last active monotone chain is established and filling of polygon is finished .

新算法首先生成多边形单调链，并对单调链尖点按Y坐标排序，最后建立活性单调链表，从而完成多边形的填充。

Polygon sorting in the light of depth often arises in eliminating hiddensurfaces of polyhedra, and the calculation to the polygon sorting is much more complex than that to number sorting.

多边形按深度排序是多面体消隐过程中常遇到的一个问题，这是一种比一般的数字排序复杂的排序。

Because of the false star existence, the biggest polygon is not necessarily the optimum match, this study introduced the concept of voting algorithm to the stars of the matched star triangles, the star polygon who takes stars with high match rate as a right identification, thus removed the false star disturbance.

因为有伪星的存在，此时的最大多边形不一定是最佳匹配，本研究引入了投票算法的理念，对组成星三角的导航星进行匹配率统计，选取匹配率高的星多边形作为正确识别，从而排除了伪星的干扰。

The double decomposition polygon clipping method is brought forward based on polygon trapezoidal decomposition. By analyzing its time complexity, the case it applicable to and its accuracy, it is pointed out that the new clipping method has a lower complexity than the old methods and does not make mistakes in the case SutherLand-Hodgman algorithm would.

在多边形梯形剖分的基础上提出了双剖分多边形裁剪算法，并对算法的时间复杂度、适用范围和处理的正确程度进行分析，指出该算法的时间复杂度低于以往算法，在处理非自交叉的多边形时结果正确，不存在类似SutherLand-Hodgman等算法处理出错的问题。

它出现在正五边形和正十边形以及正12面体（一种规则多面体，它的每个面都是正五边形）中是易于观察到的。

They are regular tetrahedral class belonging to tetrahedral group , regular hexahedral class and regular octahedral class belonging to octahedral group. Be...

并且分析和表征了它们的几何特征和生长规律，从而为DNA多面体的合成和蛋白质多面体链环的构筑等提供理论模式。

Results Two new characterizations of regular rings are given.(1) If R is a left SF'-ring and R/Z is reduced, then R is strongly regular;(2) R is strongly regular if and only if R is a left SF'-ring whose every idempotent element of R is left semi-center and is LANE-ring.

结果 得到了SF'-环是强正则环的两个充要条件：(1)R是左SF'-环，如果R/Z是约化的，则R是强正则环；(2)R是强正则环当且仅当R是满足幂等元左半中心的左SF'-环，且R是LANE-环。

Further,we findalso that groups in Saito's results may be replaced by right groups;secondly we mainly investigatethe semidirect products and wreath products of P-regular semigroups;Finally we shallcharacterize the sandwich matrice of completely simple P-regular semigroups,and investigate thestructure of P-regular semigroup whose C-set satisfies a permutation identity.

在这一章中，首先指出Saito在研究半群的半直积和圈积时，对S的限制是不必要的，证明了Saito结果中群可换为右群；其次，研究P—正则半群的半直积和圈积；最后刻划了完全单P—正则半群的夹心阵和C—集满足置换恒等式的P—正则半群的结构。
