检定钢尺温度误差的改正方法探讨

Approach To The Correction Of Examining The Temperature Error Of Steel Ruler

本文利用线性回归分析的基本理论和方法,对钢尺检定时温度的误差改正计算方法进行了研究,合理地建立了尺长随温度变化的数学模型,对钢尺检定的温度改正数提出了较为科学的理论根据和计算方法.

Based on the theories and methods of linear return analysi s,the Correct computing technology forthe steel ruler's examining temperature i s studied in studied in this article. The author establishes The mathematical model that could change with temperature rationally and puts forward t he comparatively scientific theoretical foundation and computing technol ogy to the temperature correction of the steel ruler.
