摘要
在科学研究、教学实验、企业测试分析过程中,会产生大量的试验数据。对试验数据进行修约、运算与处理,直接关系到测试结果的准确性和结果判定的合理性。在标准视角下,结合经验法则,通过教学与企业检测实例对有效数字修约在适用范围、修约间隔、四则运算、结果判定等疑难点问题上进行探讨分析,旨在帮助检测分析人员、大学生更好地理解标准在有效数字修约与运算的作用,能够运用标准和经验法则(ROT)提升测试结果和判定的准确性。
In the process of scientific research,teaching experiments,and enterprise analysis,a large number of test data will be generated.Rounding off and processing of test data is directly related to the accuracy of test results and the rationality of result judgment.From the perspective of standard,combined with rules-of-thumb(ROT),the doubtful and difficult problems were discussed in rounding off significant figures based on the examples of teaching and enterprise testing,such as the scope of application,rounding interval,four arithmetic operation,result judgment and so on.The purpose of the research is to help test analysts and college students to better understand the role of standards in rounding off and calculating significant figures,and standards and rules of thumb(ROT)were used to improve the accuracy of test results and judgment.
