查询词典 angle

The effect of Reynolds number on rudder hydrodynamic performance is also analyzed. Up to the stall angle the computed lift and drag agree well with measurements and other author's calculations, whereas stall angle, lift and drag beyond the stall angle are slightly under-predicted. The solver is used to investigate laminar and turbulent separated flows around a 6: 1 prolate spheroid at high incidence angles and their effects on hydrodynamic forces. The second separation flows are successfully identified in both laminar and turbulent flow simulations.

应用所开发的求解器，以6：1长椭球体为算例计算了回转体在大攻角下定常斜航运动时的三维粘性流场及水动力，对层流流动和湍流流动分别进行了计算，分析了层流与湍流分离流动和涡旋产生的特点及其对水动力的影响；计算结果与他人的试验和计算数据比较，吻合程度良好，表明应用本求解器能够正确模拟这种以层流／湍流分离流为主的复杂粘性流动，得到相当精确的水动力，检验和验证了该求解器精确模拟回转体在大攻角下的粘性分离流动和计算水动力的能力。

Judging on the radioactive rays whether they penetrated through the truncated right angle cone shield configuration. A hypothetical circumscribed rectangular parallelepiped of the they penetrated through the truncated right angle cone shield configuration. A hypothetical circumscribed rectangular parallelepiped of the truncated right angle cone shield configuration is also presented. The methods simplified the camber equation and reduced the calculation time significantly.

在判断放射线是否穿透此圆锥台体时，又提出了圆锥台形屏蔽体的假想外接长方体的建模方法，将曲面方程联立解的复杂计算简化为一次代数方程的简单计算，大幅度地缩短了计算时间。

In rectilinear motion,the extremum of pullvaries with the factor;angleθ=α=arctgμ(μ:friction factor;angleθ:the angle between the direction of pull and the motion direction).

在直线运动中拉力 F的极值随摩擦系数μ的变化而变化，当θ=α=arctgμ(μ为摩擦系数，θ角为拉力 F和运动方向的夹角)时，F有极小

An angle that is not a right angle or a multiple of a right angle.

At last, the muzzle sinkage of rocket mechanics and effect are researched, and thechanging rule of the pitch angle, yaw angle, slope angel and offset angle are analysed. Whichis very necessary to simulation analysis on warhead sinkage.

最后，研究了炮口下沉的机理及影响，并对其进行了动力学仿真分析，得到了在不同射角情况下，火箭弹的俯仰、偏航、弹道倾角及弹道偏角的变化规律，对提高弹箭武器的射击精度具有一定的参考价值。

By contrast with the spectral obtained under different incident geometry and polarized conditions, the experimental results show that the reflected light can be corrected completely with an incident zenith angle of 53 degree (Brewster's angle) and zero polarized angle.

结果表明，当探测角不满足布儒斯特角时，在偏振片的主消光方向能剥离绝大部分的水面反射光；当入射角越接近布儒斯特角，其剥离效果越佳；以布儒斯特角观测时，可以达到完全剥离的效果。

A right angle is an angle of 90°,and a straight angle is one of 180°.

直角是90°角，平角是180°角。
