Origin软件在实验数据处理中的应用——以燃烧热测定实验为例

目的研究Origin软件在实验数据处理中的应用，即以Origin软件代替手工方法对实验测定的数据进行绘图、计算、拟合等。方法以燃烧热测定实验为例，用Origin软件对所得数据分段线性拟合绘制雷诺校正图，并与学生手工绘图处理的数据对比。结果由于数据点多，传统用坐标纸手工绘图，不仅耗时，而且处理结果因人而异，人为因素往往会对实验结果带来一定的误差。而采用0rigin软件处理实验数据，不仅比手工绘图处理所得绺果更准确，而且节省时间。结论0rigin软件应用于处理实验数据，可以有效消除人为误差，节省时间，所得结果更为准确、可靠。

Application of Origin software in data processing of combustion heat determination

Objective--To study on the application of Origin software in data processing of combus- tion heat determination, such as plotting, calculation and fitting with Origin software instead of man- ual methods. Methods--Taking the data measured from combustion heat experiment as examples, the data processed with Origin software was compared with that with manual method after Reynold cor- rection curves were plotted by piecewise linear fitting with Origin software. Results--Data processing with graph paper is time-consuming and the test result varies from student to student, while the data processing with Origin software is more accurate and time-saving. Conclusion--The artificial errors can be avoided when Origin software is used to processing the data and the result obtained from Origin processing method is more reliable from than that from graph paper method.
