摘要
灵敏系数是不确定度计算的关键因素,在实际测绘仪器计量检定过程中,输入量的采集方式为不同目标多次测算方式,利用公式计算测量结果,获取输出量。在测量不确定度过程中,基于数学模型的繁杂性,致使对输入、输出量的灵敏系数获取难度加大。文章简要介绍了强行偏导法、方差比例法、传递继承法的计算方法,获取其中的灵敏系数,解决测绘仪器测量不确定度的技术问题。
Sensitivity coefficient is the key factor in the calculation of uncertainty. In the process of measurement and verification of actual surveying and mapping instruments, the collection mode of input is multiple measurement of different targets, and the formula is used to calculate the measurement results and obtain the output. In the process of measuring uncertainty, based on the complexity of the mathematical model, it is more difficult to obtain the sensitivity coefficient of input and output. This paper briefly introduces the calculation methods of forced partial derivation method, variance proportion method and transfer inheritance method, obtains the sensitivity coefficient, and solves the technical problem of measurement uncertainty of surveying and mapping instruments.
