axis of rotation 英 [ˈæksɪs ɒv rəʊˈteɪʃn] 美 [ˈæksɪs əv roʊˈteɪʃn]转动轴
A rotor adapted to rotate about a rotary shaft and intended for displacing fluids characterized in that the rotor comprises at least two ridges arranged helically around a core part so that a sectional area at right angles to the axis of rotation comprises at least two lobes with intermediate ...

The meaning of ROTATION AXIS is a simple axis of symmetry in a crystal about which the whole crystal configuration is brought into coincidence with its original aspect by a rotation of one half, one third, one fourth, or one sixth of a turn about the axi

In this paper, we propose two new algorithms to correct the trajectories of the tool tip of a five-axis milling machine by adjusting the rotation angles in such a way that the kinematics error is reduced. The first algorithm is based on the shortest-path optimization with regards to feasible...
Perceived orientation of axis of rotation and accuracy in discriminating fixed-axis from nonfixed-axis rotations were investigated for orthographic projections of three-dimensional rotating objects. The principal findings were (a) the slant of the axis of rotation was systematically misperceived; (b) in...
The first rotation of the elbow JCS (α about e1) roughly gives the flexion angle and is calculated as the angle between the floating axis, ef, and a reference axis fixed to the first body (taken to be I), that is, α = cos− 1(ef . I). Similarly, the rotation γ about e3 ...
The propagation direction of SAW is along the X-crystalline axis of the LiNbO3 substrate, which is defined as x-axis. Along this propagation direction, the SAW is Rayleigh-mode, which means that the vibration is only along the x and z directions. Therefore, there are three nonvanishing ...
