基于MATLAB网络系统评价学生物理化学实验结果

Evaluating the Physical Chemistry Experiment Results of Students by the Network System Based on MATLAB

应用MATLAB软件和ASP.NET混合编程,构建评价学生物理化学实验结果的平台,具有重要的现实意义。本文以物理化学实验"最大泡压法测定溶液的表面张力"和"电导法测定乙酸乙酯皂化反应速率常数"为例,探讨了所构建网络系统在评价实验结果中的应用。该系统不仅能对实验数据进行分析和计算,还能直观地绘制出相应的图形,从而方便学生在完成实验后快捷、客观、准确地评价所获得的实验数据,有效提升了物理化学实验的质量。

It is of great practical significance to build a platform to evaluate the results of students’physical chemistry experiments through the MATLAB software and ASP.NET integrated programming.Taking two physical chemistry experiments of"Determination of solution surface tension by maximum bubble pressure method"and"Determination of saponification rate constant of ethyl acetate by conductivity method"as the examples,the applications of constructed network system in the experimental result evaluation were studied.It is found that,this system can not only analyze and calculate experimental data but also draw the corresponding graphics intuitively.It is convenient for students to evaluate the experimental data quickly,objectively and accurately after finishing the experiment,effectively improving the quality of physical chemistry experiments.
