摘要

二极管伏安特性研究实验是大学物理实验中的重要基础实验之一。测绘二极管的伏安特性曲线一般采用伏安法进行测量。在实验过程中，学生需要测量二极管两端的电压和流经二极管的电流，并用此来绘制二极管的伏安特性曲线。学生在实验过程中如果能够快捷绘图，以此来及时自检并发现测量数据的问题，对于提高“二极管伏安特性研究”实验的教学效率至关重要。我们采用ＪａｖａＳｃｒｉｐｔ语言编写了快捷绘图程序，为学生提供了快捷网页绘图终端。学生在测量完数据后，通过手机浏览器进入绘图终端，输入测量数据，即可绘制电压和电流的关系曲线（ＵＩ曲线）。 “二极管伏安特性研究”实验教学过程中快捷网页绘图终端的引入，可以显著提高学生的学习效率和教师的授课效率。

Abstract:

The “research on the volt-ampere characteristics of diodes"is one of the important experiments incollege physics experiments. The volt-ampere characteristic curve of diode is generally measured byvoltammetry.During the experiment,the volt-ampere characteristic curve of diode should be drawn by using themeasured voltage drop across the diode and the measured current flowing through the diode.The quick drawingof the volt-ampere characteristic curve is very important for enhancing the teaching efficiency. Based onJavaScript,we write drawing program which can provide college students with web quick drawing client.Thecollege students can enter the measured data in the drawing client through the mobile browser. And the drawingprogram would give the volt-ampere characteristic curve. The introduction of web quick drawing program in theteaching process of " research on the volt-ampere characteristics of diodes" can significantly improve thelearning efficiency of the college students and the teaching efficiency of the teachers.

Key words: voltammetry volt-ampere characteristic curve drawing program web drawing client quick drawing
