平角

At the same time convert the angle of the polygon at that vertex into a straight angle.

同时把该顶点处多角形的角转换成平角。

The influence of the steering wheel alignment parameters (consisting of caster, king-pin inclination, camber and toe-in) and tyre meandering frequency on the vehicle shimmy is systematically studied. Some new conclusions having practical value are obtained and proved by the road test.

利用所建的汽车摆振数学模型，系统地研究了转向轮定位参数（包括主肖后倾角，主肖内倾角，车轮外倾角和车轮前平角）和轮胎蛇形运动频率对汽车摆振的影响规律，获得了许多新的具有实用价值的结论，并得到了道路试验结果的证实。

Experiments exposed that the inner flow of tooth space in the micro-channels was proved to be cycled flow after fully development. For the more, low velocity vortex cavities existed in the vertex angle and inner side of bend angle of straight angle micro-channel, while back flow only appeared in the internal side of bend angle of round angle micro-channel. It's easy to take place deposition in the low velocity vortex cavities, which is the main cause of blocking.

试验发现各类微通道齿间内流充分发展后是一种重复性流动，平角微通道顶角和转角内侧存在低速涡旋区，圆角微通道只在转角内侧出现回流，颗粒在低速涡旋区易发生沉积，是造成堵塞的主要原因。

It has been suggested that the architecture of the lower lumbar vertebrae and sacrum (e.g., inadequate separation between the inferior articular process of L4 and the superior articular process of L5, a wedged-shape interfacet region of L4, a more frontally oriented lumbar facet, and a wider sacrum), pelvic orientation and lumbosacral parameters (e.g., pelvic incidence, sacral table angle) may play a role in the development of spondylolysis.

低位椎体和骶骨的结构（如L4下关节突与L5上关节突间隔不足，L4下关节突成楔形，腰椎小关节方向过分偏额面方向，骶骨过宽），骨盆方向和腰骶段的参数（如骨盆影响和骶骨水平角）可能在脊柱滑脱的发展中扮演重要角色。

My pants are small now, I want to buy some br ie f.

我的平角裤小了，想买几条三角裤。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
