一、概述随着我们工业、农业、国防和科学技术的发展,很多单位已经研制出了高精度轴承。目前,在测试这种高精度轴承的误差时,有的用高分辨率的电感传感器,有的用乌氏干涉仪等方法,尽管这些方法的测量精度都比 First, an overview With our industrial, agricultural, national defense and the development of science and technology, many units have developed a high-precision bearings. At present, the test of such high-precision bearing error, and some use high-resolution inductive sensors, and some use U-shaped interferometer and other methods, although these methods are more accurate than the measurement
