| 摘 要： | 不确定度是建立在误差理论基础上的一个新概念。误差的数字指标称为不确定度。它表示由于测量误差的存在而对被测量值不能肯定的程度,不确定度是指测量结果带有的一个参数,用以表征合理赋予被测量的值的分散性。下面,我将通过实例来具体说明它的计算工程。

| Abstract: | The indetermination degree is a new concept which is based on the error margin theories. The numeral index sign of error margin is called an indetermination degree. It means the unsure degree of the measured value because of the existence of error margin. The indetermination degree is a parameter with the measuring result, in order to token reasonable of the dispersion of the measured value. Then, I will explain how to calculate the process of it by setting example. |
