我们知道,当量仪设计或进行测量时,由于量仪的结构限制,往往使量仪的测量轴线不能与基准轴线在同一条直线上,这样就必然会因为不符合阿贝原理而产生理论误差,这种误差,我们通常称之谓阿贝误差,亦称一次误差。以纵向比长仪为例,如图1所示,由于基准尺与被测尺并列,它们不在同一条直线上,即违背了 We know that when the gauge design or measurement, due to the structural limitations of the gauge, the gauge axis is often not in line with the reference axis in the same straight line, so inevitably because of the Abbe principle does not produce theoretical errors, This error, we usually call Abe error, also known as an error. Longitudinal ratio than the instrument, for example, as shown in Figure 1, as the ruler and the measured scale side by side, they are not in the same straight line, which is contrary to
