摘要
从实验设计、科学常数取值、误差的有效数字表示与近似原则三个方面分析了微小误差准则在科学实验中的应用和重要地位,得到微小误差准则在科学实验和实验教学中的一般应用规律,有效提高科学实验的精度.
In this paper, the important functions of minor errors＇ rule in scientific experiment have been analyzed successfully from three aspects. The first is experiment design, the second is precise valuing scientific constant, and the third is the significant figure expression and approximate method of error, which results in the general applied rules of minor error rule in the scientific ex- periment and experiment teaching, and effectively promote the precision of the scientific experiment.
