The secondary mass flux, Z, cavity convergence/divergent angle, and injection angle have different effect on internal performance of DTN.

二次流量、落压比、凹腔扩张角和收敛角、引射角度都对推力矢量状态下的DTN内流性能有着不同的影响。

To get the steady interface, the ratio of coextrusion flow length to height is at least l-1.5._The role of smooth flow zone is important to reduce the pressure-fall. The higher surface quality of the fluid path can make the velocity field more uniform and the interfacial offset less. However, the layer interface position was almost unaffected by the convergence angle, so for the convenience of die manufacture and extruder\'s collocation, it is fit to make the contact angle as 90°with smooth corner.

在模具结构参数中，共挤出流道的长度和模具壁面光滑程度对界面有重要的影响，根据计算结果得到了方形流道共挤出段长度与高度比的取值范围；而模具入口收敛角对界面的影响不大，在实际生产中为了模具制造和共挤出机布置的方便，可采用圆滑过渡的90°入口角。

In order to ensure the precision and reliability, this paper designs the GPS/Loran C/SINS/AHRS integrated system. In this integrated system, the self-adaptive federated Kalman filter is introduced to revise strap-down inertial navigation system; the heading angle attitude and heading reference system is used to ensure the convergence of heading angle; and the coordination transformation for Loran C is applied to eliminate the constant error of Loran C.

针对导航精度及可靠性，设计了GPS/罗兰C/SINS/AHRS组合导航系统，该组合导航采用了自适应联邦卡尔曼滤波的方法，通过闭环形式校正SINS，并用姿态航向参考系统代替捷联惯性导航系统输出的航向角以保证航向角的收敛，同时对罗兰C的测量值进行坐标变换以消除由于坐标系不同而带来的常值误差。

Bradley explained this effect in the context of Newton's corpuscular theory of light, by showing that the aberration angle was given by simple vector addition of the Earth's orbital velocity and the velocity of the corpuscles of light (just as vertically falling raindrops strike a moving object at an angle).

布拉德利解释这种效应的背景下，牛顿corpusculartheoryoflight，经表明像差角度作了简单的载体，增加了地球的轨道速度与速度段体轻(就像垂直下落雨滴罢工运动物体的夹角)。

Cos public static double cos Returns the trigonometric cosine of an angle. Parameters: a - an angle, in radians. Returns: the cosine of the argument

Cos函数返回三角的余弦函数，参数a是一个以double类型的弧度表示的角值，返回类型为double。

It barred the vast opening of the faubourg, that is to say, three streets, from angle to angle; ravined, jagged, cut up, divided, crenelated, with an immense rent, buttressed with piles that were bastions in themselves throwing out capes here and there, powerfully backed up by two great promontories of houses of the faubourg, it reared itself like a cyclopean dike at the end of the formidable place which had seen the 14th of July.

它挡住进入那一郊区的一大片岔路口，就是说，从这端到那端，它连续遮拦着三个街口，忽高忽低，若断若续，或前或后，零乱交错，在一个大缺口上筑了成行的雉堞，紧接着又是一个又一个土堆，构成一群棱堡，向前伸出许多突角；背后，稳如磐石地靠着两大排凸出的郊区房屋，象一道巨大的堤岸，出现在曾经目击过七月十四日的广场底上。

At all angle s less than the critical angle , both reflection and refraction occur.

对于所有小于临界角的入射角，则既发生反射，又发生折射。

In harsh environment, the precision measurement of the axis angle is critical for the development of space system. The factors such as temperature variations and platform vibration severely limit the accuracy and life time of axis angle measurement device in space.

在复杂恶劣的气候条件下进行高精度的轴角测量已经成为发展空间应用技术的主要瓶颈，其中空间温度交变和振动环境，严重制约着空间用轴角测量装置的精度和使用寿命。

A detailed calculation on the scattering of a conduct disk is given by means of Incremental Length Diffraction Coefficient method and Phyzical Optics method. The relation between Radar cross section of the conduct disk and the incident angle and the relation between the optimal polarization and the incident angle are investgated and the calculation results from ILDC and that from PO are compared.

用微分边缘绕射系数法和物理光学法对金属圆盘的散射作了详细地分析计算，讨论了其极化散射特性给出了雷达截面积随角度的变化曲线并与用物理光学法计算的结果进行了对比，同时还给出了其最优极化随角度变化时的分布图。

Must have Coordination and negotiation skill, flexible ideas, and be punctilious person.

必须具备较好的协调与谈判能力，头脑灵活，工作认真仔细
