摘要
两变量间的线性关系y=A+Bx是物理实验中常见的研究对象,本文定量讨论用最小二乘法和逐差法进行线性拟合时,所求得的斜率的标准差的关系及因变量的误差对斜率误差的影晌。
The linear relation of two variables y=A+Bxis a frequent subiect of research in physiccal experiments.This paper discusses,when linear fitting is going on by using suceessive difference method and least square method,the relation of slope's stardard deviations and the effect on slope's errors because of errers of variables.
