摘　　要：精度估计是线性参数处理中重要的一部分,而累积法是进行线性参数处理的一种新方法。为此在简述了普通累积法的概念和进行线性参数估计的原理之后,推导出了等精度测量时线性参数精度估计的计算过程和公式,并以测量铜棒长度和线性膨胀系数为例,对其进行了精度估计。结果表明,计算过程简便、公式正确。对于不等精度测量,只需要转化为等精度测量即可。Accuracy estimation is an important part in linear parameter processing, and cumulative-sum method is a new method for linear parameter processing. The fundamental concept of this method and principle of its application in linear parameter estimation are introduced. The computing procedure and formulas of accuracy estimation in equal accuracy measurement are proposed. With an example of the length and linear expansion coefficient measurement of a copper bar, the accuracy is estimated. The results show that the computing procedure is simple and convenient, and the formulas are correct. In the unequal accuracy measurement, the data can be converted into equal accuracy data.
