摘要:

介绍了一种Origin制图方法,直接绘制燃烧热测定实验中的雷诺温度校正图,用于处理燃烧热实验数据。与手工坐标纸作图相比,Origin直接制图法精度高,误差小,简便快速。与计算机多段分别线性拟合法相比,Origin直接绘图法不仅同样精度高、误差小,而且更加直观,更能反映雷诺制图法的本意,且能够直接观察到燃烧热实验的热漏情况。Origin直接绘制雷诺温度校正图法兼具手工作图和计算机线性拟合法二者的优点,值得推广。

Abstract:

In this paper, an Origin mapping method is introduced, which can directly draw the Renolds temperature correction chart in the combustion heat measurement experiment for further data process. Compared with manual drawing, Origin has the advantages of high accuracy, simplicity and rapidity. Compared with the computer multi-segment linear fitting method, Origin not only has the same high accuracy, but also is more intuitive, reflecting the original intention of Renolds mapping method better, and can directly observe the heat leakage of combustion heat experiment. Origin's method of directly drawing Renolds temperature correction diagram has the advantages of both manual drawing and computer linear fitting, and it is worth popularizing.

Key words: Heat, Origin, Renolds
