激光垂准仪一测回垂准测量标准偏差校准的精度分析

摘要

根据JJF1081-2002《垂准仪校准规范》的规定,采用测量不确定度A类或B类评定方法,在观测条件正好处于合格条件的临界状态的情况下,对垂准仪一测回垂准测量标准偏差校准的测量不确定度进行评定,并给出垂准仪在实际使用中一测回垂准测量标准偏差的预警值。%In accordance with Calibration Specification for Plumb Instruments JJF1081-2002,this paper evaluates the uncertainty for Plumb Standard Deviation Calibration for plumb instruments of one circle Measurement,adopting type A or B evaluation for uncertainty measurement under qualified critical state of observation.Meanwhile,the paper indicates a warning value for plumb standard deviation calibration for plumb instruments of one circle measurement in practical use.
