1)semi-cone angle半锥角 1.Influences of main parameters such as rotation speed, blade thickness,semi-cone angle and lead of screw conveyor on its strength and deformation were studied.在诸多参数中,对螺旋离心输送器主要参数:转速、叶片厚、半锥角和导程对其强度和变形的影响进行了分析研究,为已有的卧式...
Angle conversion of solid angle of a cone to an apex plane angle. A solid angle is similar in 3 dimensions to a plane angle in 2 dimensions. Asolid angle Ω is equal to the ratio of the viewed surface A divided by the square of the viewed distance r. What is the formula to find t...
The conical angle of cone-shaped active magnetic bearings is studied. Amodel of a conical bearing system and load forces is made. A minimax decision approach is used with the model. The conical angle is optimized so that the control forces required are as small as possible for a given load...

a surface formed by rays having a common origin and passing through a closed curve (Figure 1). Sometimes, particularly in Soviet usage, the term “solid angle” is applied to the portion of space bounded by such a surface. Trihedral and polyhedral angles are special cases of solid angles. ...
Modelling of Electromagnetic Scattering by a Hypersonic Cone-Like Body in Near Space Based on the parameters of Table 1 and formula (16), we can calculate the numerical values of [D.sub.Nor] as 0.0016 under 0[degrees] attack angle, 0.00196 under 15[degrees] attack angle, 0.00219 under 30...
The blade arc radius and length are similar for the purpose of comparison for both the cylindrical and half-cone rotors whether the blades are leaned or not. The lean angle (β) is defined to be positive when it is in the direction of rotation and if otherwise, it is considered as a ...
, the transmission spectrum is “blue shifted,” which means the spectral features shift to shorter wavelengths (Figure 3). This angle shift becomes more pronounced with increasing AOI and can be calculated in collimated light and for relatively small angles of incidence using the following formula...
