本条数据采用的设备为ZYGO公司生产的NewView9000型3D表面光学轮廓仪，放大倍数为10x，测量对象小尺寸轴件的非配合表面，由于未发生接触，因此可以视为未发生磨损的表面，对其表面进行多次测量，将测量结果与进行试验之后的磨损表面进行比较。本文件夹为未发生磨损的实验轴件的径向表面不同位置的形貌采集图片，2d为平面照片，3d为立体照片，origin为平面黑白照片，相对2d是为了方便观测。

The equipment used in this article is the NewView9000 3D surface optical profilometer produced by ZYGO Company with a magnification of 10x. The non-fit surface of the small-size shaft of the measurement object can be regarded as the surface without wear due to the lack of contact, and its surface is measured several times. The measurement results are compared with the worn surface after the test. This folder is a collection of morphologies of different positions on the radial surface of the experimental shaft without wear. 2d is a plane photo, 3d is a stereoscopic photo, origin is a black and white photo, and 2d is for the convenience of observation.
