The correct exposure point of view, should be the angle of incidence equals the angle of reflection.

侧确的照射角度，答当是入射角即是不正射角。

Another object of my invention and one of the primary ones is to provide such a section and means for changing the angle of incidence of the section with respect to the angle of the primary wing surface of a seaplane of which it may be an essential part.

另一个目的，我的发明和其中一个主要的是要提供这样的一节和手段，改变入射角，该科与尊重的角度来看，主要翼面的一个水上飞机的，它可能是一个不可或缺的部分。

The measurement of the inclination angle and the azimuth angle of a well in the drilling process is important.

钻探过程中钻井的倾斜角和方位角的测量至关重要。

The results show that the surface roughness decreases with increase of the inclination angles within the range of 10° to 30°. After the angle approaches to 30°, increase of the inclination angle causes increase of the surface roughness. Furthermore, the effect of inclination angles on cutting speed was investigated.

研究结果表明：工件倾角的大小对已加工表面粗糙度有明显的影响，在倾角为10°～30°时，表面粗糙度随着工件倾角的增大而降低；此后，随着倾角的进一步增加，表面粗糙度有所升高。

The angle or inclination of a line or surface that meets another at any angle but90=.

The results show that the change of the intersection angle is less than 1 when the temperature operating condition has been changed. It is concluded that the quantitative measurement method can get the accurate change of the intersection angle, and measurement data can provide important references for the ground analysis with three-line mapping cameras.

结果显示，测试相机在工况转变后交会角的变化在1以内，表明该测量方法可以准确得到相机交会角的变化量，测量数据对三线阵立体测绘相机在轨测量及地面影像分析提供了可靠的依据。

It is given that the connection between interception probability and orbit intersection angle as well as time error under the instance that the main body of objective satellite is destroyed. The choice of orbit intersection angle is expatiated when time error exists by simulation calculation.

研究了对目标卫星主体毁伤情况下，轨道交角和交会时间偏差与拦截卫星拦截概率之间的关系；阐述了有一定交会时间偏差时，轨道交角的选择情况，并对其进行了仿真计算。

First, the phenomenon of the projectile-retarded mechanism of moving plates is introduced, the conditions of the projectile-retarded mechanism of moving plates is analyzed. By a number of numerical simulations, the residual length and residual velocity of the rod which penetrate the fixed plate is contrasted with those of the moving plate. Under the different velocity of moving plate, the relationship between the effect of the projectile-retarded moving plates with thickness and intersection angle of the projectile-retarded moving plates is achieved, and the most optimal thickness and intersection angle is gotten.

首先介绍了运动板抗弹作用的现象，分析了产生运动板抗弹作用的条件，利用数值计算的方法，对比了长杆侵彻固定靶板和运动靶板后长杆的剩余长度和剩余速度，分析了不同的运动板速度条件下产生运动板作用的条件，得出了运动板抗弹效果与靶板厚度和夹角的关系，得到了产生运动板抗弹作用的最优靶板厚度和夹角。

Design variables include the artificial satellite number, orbit inclination angle, geographic longitude of intersection of two constellations, and every constellation is hit by the 1st artificial satellite phase angle.

提出IGSO星座的优化设计方法：以一种双"8"字形、共轨道面的IGSO星座构型为例进行星座设计，设计变量包括卫星数目、轨道倾角、2个星座的交点地理经度，每个星座中第1颗卫星的相位角。

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。
