物理实验中微小量测量的研究

Study of Measure for Minimus Quantity in Physical Experiment

物理实验中主要采用放大法来进行微小量的测量,本文针对拉伸法测金属丝的杨氏模量和用牛顿环干涉测透镜的曲率半径这两个实验的测量和误差分析来阐述放大法在微小量测量中的适用性、巧妙性,并讨论导致微小量测量误差的主要因素。

Enlarging method is one of important methods to measure minimus quantity in physical experiment. As the examples,two experiments have been introduced in this paper by Enlarging method,and measurement errors were obtianed. As a result,applicability and felicity of Enlarging method was introduced.
