摘　　要：在某回转轴系上建立了一系列坐标系 ,通过坐标系之间的姿态关系分别推导了用水平仪测试法和自准直光管测试法测试主轴轴系倾角回转误差时水平仪和光管的读数表达式。根据水平仪和自准直光管读数中的各个误差组成部分和倾角回转误差在它们中的表达式的区别 ,得出了水平仪法能测试出主轴回转误差中的一次谐波成分 。A series of coordinate systems is set up on a perpendicular axis,and by the attitude relations among coordinate systems,the equations of readouts of the level instrument and the autocollimator are deduced when they areused to measure the wobble error of the axis system.The deduced equations consist of many kinds of errors.From the differences of the wobble errors in their equations,the conclusion that level instrument can measure the first harmonic wobble error,while the autocollimator can not measure the first harmonic wobble error is drawn.
