本条数据采用的设备为普通照相机。对实验之后的小尺寸试件进行拍照，对非配合表面损伤情况进行保留，通过其表面的损伤来判断其旋转次数。

0：轴件实验前不同角度的照片

10：轴旋转2×10⁵次后不同角度的照片

30：轴旋转2×3×10⁵次后不同角度的照片

50：轴旋转2×5×10⁵次后不同角度的照片

70：轴旋转2×7×10⁵次后不同角度的照片

100：轴旋转2×10×10⁵次后不同角度的照片

The equipment used for this data is an ordinary camera. After the experiment, the small-size specimen was photographed, the damage of the non-fit surface was retained, and the rotation times were judged by the damage of its surface.

0: Photos from different angles of the shaft before the experiment

10: Photos from different angles after axis rotation 2×105 times

30: Photos from different angles after axis rotation 2×3×105 times

50: Photos from different angles after axis rotation 2×5×105 times

70: Photos from different angles after axis rotation 2×7×105 times

100: Photos from different angles after axis rotation 2×10×105 times
