在《互换性与测量技术基础》（以下简称《互》）书中，大多是这样论述“精度”及其有关术语的：“通常所谓加工或测量的‘精度’，是表示加工所得实际参数值对其理论值或测量所得值与其真值的近似程度。可以用‘精密度’表示随机误差影响的程度；用‘准确度’（正确度）表示系?
Most of the book “Basics of Interchangeability and Measurement Techniques” (hereinafter referred to as “Mutual”) discusses “precision” and its related terminology as follows: “The so-called” precision "of processing or measurement means the actual parameter The value of the theoretical or measured value and its true value of the degree of approximation. Can be used ’precision’ to indicate the degree of random error; ’accuracy’ (accuracy) that?
