物理实验中有效数据的读取计算及结果表示法

The Way to Read and Compute Virtual Value and How to Express the Result in the Physical Experiment

在物理实验中,对仪表的有效数据读取、运算常常出现错误.本文着重论述了一些常用仪器有效数字的读取方法及其内涵,论述了如何写出正确的结果表达式;对模拟式仪表有效数字的读取方法进行了比较并得出正确的方法;对数字式仪表也指明了正确的读取方法;最后对有效数字处理方法及其含义进行了说明.

In physical experiment mistakes usually appeared at the reading of data and also the computation of virtual value. This paper also discusses the way to read virtual value for instruments in common use and its really meaning. The correct way to read virtual value in analog instruments is gotten through the comparison of every way and also the digital instrument. In the end, the paper explains the processing of virtual value and its meaning.
