仿真结果表明，尺度减小，磨损系数变小，增大载荷或增加微枢轴旋转次数均会加剧磨损程度。

It is indicated that the wear coefficient decreases with the decrease of the scaling and the wear becomes serious with the increase of the applied loading or the rotation Numbers.

这是一个无人驾驶的双翼飞机，它有着自动钢琴的风箱来为回旋装置提供动力，以及一个收银机的机械装置——通过记录类似螺旋推进器的转子的旋转次数来计算飞行的距离。

It was an unmanned biplane with player-piano bellows to power its gyroscope and a cash-register mechanism that calculated distance flown by counting the rotations of a propeller-like rotor.

相对于传统立体视觉，旋转立体视觉具有标定次数少、成本低、易于对物体实现整体重建等优点。

Compared with traditional stereo vision, rotational stereo takes advantages of lower cost, less calibration and being easy to reconstruct entire three-dimensional objects.
