The utility model discloses novel screw telescopic chopsticks which are characterized in that the travelling hygienic chopsticks can extend and shrink by a rotatory movement.
Guide bearing of vertical hydrogenerator carries the radial force from its rotatory parts.
On the basis of the author's former paper, in this paper the forced vibrations of rectangular orthotropic plates taking into account the shear deformation and rotatory inertia are discussed.
There are many helixes of dihedral Angle, and the whole skeleton forms a large helix in the structure of the rotatory isomer.
To observe the voice rehabilitation of the patients received extended partial laryngectomy repairment with rotatory door muscle skin flap.
From numerical example, the effect of shear deformation and rotatory inertia on the natural frequencies of the Timoshenko clamped beam is discussed under different slender conditions.
Objective: To study the traits of intra-stress distribution of lumbar during rotatory manipulation.
The results show that, for given homogeneous light, the rotatory power increases with increasing temperature.
