凸角

The algorithm solves the problem of unequal width caused by method of angular bisectrix and avoids the distortion problem caused by method of circular arc for convex vertex.

在分析了已有的缓冲区生成算法后，本文提出了一种基于凸角圆弧法和目标的拓扑空间关系的快速的缓冲区自动生成算法。

In an embodiment of the present invention, a cam may be provided with a main exhaust lobe, a partial bleeder lobe and an inner base circle portion between the two lobes.

在本发明的实施例中，凸轮可具有主排出凸角、部分排放凸角和在两个凸角之间的内基圆部。

A larger preoperative thoracic kyphosis angle, greater immediate postoperative thoracic kyphosis angle decrease, thoracoplasty, and male sex correlated significantly with PJK.

一个更大的术前胸椎后凸角、更明显的术后胸椎后凸角减少、施行了胸廓成形术和男性等矫正因素与PJK显著相关。

The kyphotic angle and lordotic angle were measured in the thoracic or thoracolumbar and lumbar regions,respectively.

分别测量胸或胸腰段和腰部的后凸角和前凸角。

Improements in ertebral height and kyphotic angle were consistently reported with balloon kyphoplasty and in a small number of ertebroplasty case series.

球囊扩张椎体后凸成形术的研究和一个小样本的椎体成形术的病例研究都报道了对于椎体高度和后凸角的改善。

The preoperative lordotic angle was significantly smaller in the kyphotic group than in the lordotic group.

后凸组术前前凸角显著小于前凸组。

Only 3 patients had burst fractures of the lumbar spine, so lordotic angle measurements were recorded for these individuals alone.

只有3个患者发生了爆裂性腰椎骨折，所以前凸角的测量方法是分别测量3个患者的前凸角。3号、6号和13号患者的术前前凸角分别为11°，、10°和 11°(平均10.6°)。

Lateral roentgenograms of the lumbar spine and the hip joint were obtained in the upright position to determine pelvic inclination, sacral slope angle, lumbar lordotic angle (L1-L5), disc angle of L5/S1, and pelvic angle (by Jackson's method).

所有病例都拍摄了竖立位腰椎和髋关节侧位片，从而确定他们的骨盆倾斜度、骶骨倾斜角、腰椎前凸角（L1－L5）、L5/S1椎间盘成角和盆腔角。

In the soft tissue measurements, the value of soft tissue facial angle and B'-Pos-FH in the first extraction group was less than those in the second extraction group significantly. After treatment all the patients had an increase in S-Ns-Pos angle, soft tissue facial angle, B'-Pos-FH and depth of mentolabial groove. At the same time, soft tissue convexity angle was diminished obviously. But the change was not significant between the two premolar extraction groups.

2在对软组织项目的测量中，治疗前第一前磨牙拔除组的软组织面角、颏沟倾角均小于第二前磨牙拔除组，治疗后2组均出现软组织面凸角减少，颏凸角、软组织面角、颏沟倾角、颏唇沟深度增加；但2组在各项测量项目的变化上无显著组间差别。

It not only can generate buffer zones for point, line, plane surface and compound objects, but also can generate buffer zones for the special objects with self-intersecting and containing several holes.

它解决了角平分线法的不等宽性问题，也回避了凸角圆弧法的失真现象，以统一的形式实现了缓冲区边界的自动生成。

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。
