Origin软件在氯化铵生成焓测定实验中的应用

Application of Origin Software in Data Processing of Determine Enthalpy of Formation of Ammonium Chloride

针对大学一年级化工、化学专业的学生进行氯化铵生成焓[ΔfHθ(NH4Cl,s)]测定实验后,通常采取手工绘图的方式来处理实验数据,不仅费时费力、偶然性大,而且不可避免地引入主观误差,往往同一组实验数据不同学生处理,结果相差很大,重现性也不好。尝试采用Origin软件对该实验数据进行作图和分析,结果表明,将Origin软件应用于处理实验数据,简单、重复性好,还明显地提高了计算结果的准确性。

The freshmen majoring in Chemical Engineering or Chemistry in university usually deal with the experimental data of the Determine Enthalpy of Formation of Ammonium Chloride with handwork drawing,which is not only slow-rate and inefficient,but also increases the relative error.Applying the origin software in dealing with the experimental data,which makes diagram conveniently and accurately as well as reduces the relative error.
