摘　　要：大学物理实验数据处理过程中变量之间的关系大多可以转化为一元线性回归问题。作图法是确定物理量间关系时常用的一种方法,而用坐标纸作图是学生进行数据处理的必要能力,但学生在坐标纸作图过程中往往会出现很多不规范问题。将坐标纸作图中经常出现的问题进行分析以及规范,并以测热敏电阻温度特性实验为例,说明坐标纸作图在大学物理实验中的应用,为大学物理实验数据处理提供依据。Most of the relationships between variables can be transformed into a linear regression problem in the data processing of the college physics experiments.Drawing is a common method used to determine the relationship between physical quantities and drawing with coordinate paper is a necessary ability for students to process data.However,a lot of irregularities may appear in the process of drawing with coordinate paper.Analyze and standardize problems that often occurred in drawing with coordinate paper.Taking the experiment of thermistor temperature characteristic as an example,the application of drawing with coordinate paper in college physics experiment is illustrated which provides the basis for the data processing of the college physics experiment.
