摘要
介绍了实验数据的分类和计取基本原理,从实际应用出发分析了有效数据的取值和运算方法。针对实验应用中对有效数字与测量数据关系、有效数字的选定及数据的表达、有效数字的取舍规则、实验数据的四则运算论证分析。
the article introduces the basic principle of the classification,and of the experimental data,analyzed from practical application values and computing method of effective data. In this paper,the experimental application of significant figures in the relationship with the measurement data,selection of significant figures and data expression,the choice of effective digital rules and arithmetic demonstration analysis of the experimental data.
