摘要
金属电阻－温度系数测定实验中，作出的R－t曲线通常为直线，实际上这种线性关系是有条件的，本文根据测量要求，用微小误差理论对其进行定量分析并给出明确结果。
In the experiment of determining the metallic resistance temperature coefficient, the R-t curve drawn is usually a straight line. However, in fact, this linear relation is viable on some conditions. Based on the requriement of measurement, this paper makes a quantitative analysis of these conditions by micro-error theory and presents clarified results.
