In order to achieve a tradeoff between vectoring and unvectoring state, the proposed parameters of DTN are: Z=3~4, secondary injection flux is about 3%, cavity divergence angle is about 10°, cavity convergence angle is 20°~30°, injection angle of secondary is about 30° by counterflow injection.

为了实现DTN在推力矢量和非推力矢量下都有较好的内流综合性能，所建议的设计参数为：落压比为3~4，引射量为3%，凹腔扩张角为10°左右，收敛角在20°~30°，引射角度为30°逆流引射角(β=30°)。

An improved algorithm of two dimensional convex hull based on included angle is proposed, and all the convex points are achieved through the maximal included angle by the increasing counter-clockwise direction. When more than one point satisfies the maximal included angle, the most distant point to the previous point is regarded as the next convex point.

It occurs when the angle of incidence is greater than a certain limiting angle, called the critical angle.

当入射角大于某个称作临界角的极限角时，便发生全内反射。

Human-triggered avalanches have the greatest incidence when the snow's angle of rest 1 is 8 between 35 and 45 degrees; the critical angle, the angle at which the human incidence of avalanches is greatest, is 38 degrees.

当积雪的休止角在35度到45度之间时，人类触发的雪崩具有最在的危险性。人类引起雪崩的临界角是最大的，是38度。

Angle of view: With 60 degs. apparent angle of field, the DF and the IOR are the only wide angle binoculars in this test.

视角：在本评测中，DF和IOR有60度表现视场，是仅有的广角望远镜。

Angle of view: These are low light binoculars and one should not expect excessive wide fields of view. Closest to 'wide angle' comes the IOR with 60 degs. apparent angle, which is sufficient to avoid the tunnel-view of its contenders.

视角：这些都是低亮度望远镜，不能期望有极宽广的视角，最接近"广角"的当属有60度表现视场IOR，远离了只有管窥视野的其它两款。

The forward kinematics is analyzed by choosing one of the mechanisms which have one, two,three or zero angle constraint.Wherein,3-CCC is a new parallel mechanism which has three angle constraints and three distance constraints, Calay\'s formular and direction cosine matrix are used to describe the rotation matrix respectively.By setting Dixon\'s and Sylvester\'s resultant with the three angle constraint equations respectively and using parameters replacement to deal with the distance constraint equations,the 64 order input-output equation of the forward kinematics is obtained under both of the methods.Numerical example confirms these theretical results and the motion simulation is shown in VC++ by integrating OpenGL.

3对高小山提出的广义并联机构进行了研究，以其中具有角度约束的并联机构进行了分析，选取具有一个、两个、三个和零个角度约束类型中各一个机构进行了运动学正解求解，其中3-CCC是一种全部由圆柱副构成的具有三个线线角度和三个距离约束的新型并联机构，文中分别用Calay公式和方向余弦两种旋转矩阵建模方法对其位置正解进行了分析，通过对三个角度约束方程分别构造Dixon结式和Sylvester结式，以及对三个距离约束方程进行变量代换分别导出了位置正解输入输(来源：4040ABC论文网www.abclunwen.com)出方程，得出64组位置正解，并使用数值算例验证了其全部根。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
