Also, in the decoration sometimes need some decorative wire feet, cheek, floriation so on, but in some home-improvement in the deliberate pursuit of large-scale collage Dingjiao Xian, lumpy Door-line, ultra-scale round roof lines, the consequences of this decoration is that it reduces the room space, but also elegant and generous Qiyun lost, but also the loss of a family should have a warm decoration taste.

还有，在装修中有时需要一些装饰性的线脚、贴脸、花饰等，但在有些家装中刻意追求拼贴大尺度的顶角线，粗笨的门套线，超尺度的圆型顶棚线，这种装饰所产生的后果是，既缩小了居室空间，又失掉了典雅大方的气韵，还丧失了家庭装修应有的温馨品位。

Since we defined the frustum, we know the angle at which the sides of the frustum meet - this is the field of view we used to create the projection matrix in the first place.

确定好锥截体，我们就知道锥截体顶角的大小—这是我们在第一个地方用来创建投影矩阵的视场。

Based on the characteristics of the gravity feed,analysing the choice of relevant parameters in feeding system ,including the definition of hopper forms and semivertex angle of hopper as well as and the calculation of material delivery speed,two kinds of feeding schemes were designed-feeding structure of double doors and feeding structure of one door.

从研究重力给料的特点出发，分析了给料系统中有关参数的选择，包括料斗形式和料斗半顶角的确定，物料速度的计算，设计出重力给料的2种给料方案，即双料门供料机构和单料门供料机构。

In order to measure accurately the refractive index of optical glass to improve the imaging quality of optical systems,several measuring methods of refractive index for optical glass were analyzed and both foreign and domestic development situations for optical glass measurement were introduced.

为准确测量光学玻璃的折射率，提高光学系统成像质量，介绍了现有光学玻璃折射率测试方法和国内外发展现状，提出了一种利用测量棱镜3个顶角所对应的3个最小偏向角的折射率测量新方法。

Puzzle 150: Isosceles vertex angle - Triangle ABC is isosceles with AB = AC.

150谜：顶角等腰三角ABC的等腰是同乙级=交流。

The result shows that average background radiation can not be deduced by using mean value theorem in visible light band.

通过计算可以表明，在可见波段，平均辐射不能用中值定理来推导，因而不能用天顶角为45度或135度的天地背景辐射来代替平均背景辐射。

This approach is base on the following idea:under not effect to the deformation of rectangular pipe,to change right angle to obtuse angle which is variant as some regular,make plain-barreled roll pass receive vertical roll shape pipe blank,and then let pipe blank entering into vertical roll pass.With continuous deformation, the difference between diagonal line of rhombus pass will be reduced to zero,finally changed into a square.

该方法的基本思路是：在不影响方矩形管变形的前提下，通过将孔型顶角由直角改为按一定规律变化的钝角，让呈卧菱形状的平辊孔型接纳呈立菱形状的管坯，接着让卧菱形状的管坯进入立菱形状的立辊孔型，随着变形的继续，逐渐缩小菱形孔型对角线之差直至为零，成为正方形。

The bottom part of the page shows a preview of the applied style and a preview of two corners so that the corner style choice can be quickly evaluated.

在本对话框页的底部显示了所应用的样式的预览和两个顶角的预览，从而可以快速评估角落样式的选择。

Theoretical analyses show that the BRF has the maximum tuning rate when the optic axis is located on the cone with its symmetric axis being on the refracted ray and apex of 45°; and the rejection of unwanted wavelength of BRF becomes the maximum when the optic axis is in the plane which contains the refracted ray and makes the angle of 45° or 135° with respect to the incident plane.

分析表明当晶片光轴处在以折射光线为轴线、顶角为45°的圆锥面上时，双折射调谐器具有最快的波长调谐速率；当光轴位于过折射光线并与入射面成45°或135°的平面内时，调谐器抑制非所需波长的能力最强。

The first one is to generate the circle for each borderline segment of the component by considering the segment length and the prescribed tolerance value. If this is not the case, the borderline segment will be equally divided into halves until the obtained circle satisfies the tolerance value over the whole borderlines of the component. The basic idea of the last two algorithms aims at covering the domain occupied by the component as much as possible. The circle generation is carried out sequentially from salient angle to the sector formed by the salient angle till the uncovered borderline segments of the component. Particularly, the three-step algorithm with gap allows that the generated circles are distributed with gap along the component contour.

二分法利用组件各边长度和设置的容差大小得到该边的候选包络圆，若该圆不满足组件所有边的容差要求，则将该边不断地对分，直至所得到的包络圆满足各边的容差要求；三步划分法和带间隙的改进三步划分法则以组件区域为划分对象，依次对组件多边形凸顶角、凸扇形区和多边形各边剩余线段划分包络圆，且带间隙的改进三步划分法则允许包络圆在组件边界上以适当的间隙分布。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
