GDOU源的电场分布的可视化研究

GDOU Source of the Electric Field Distribution of Visualization Research

使用有限长均匀带电直线段组成的GDOU(广东海洋大学的英文缩写字母)的带电源,求出每条带电线段的平面电场,并对其平面上的电场进行叠加,以此建立数学模型,通过Visual C++软件编程实现图像演示,对其进行电场的可视化研究,得到了美丽的电场分布曲面。通过此研究,利用Visual C++具有的强大画图功能更好地掌握计算有限长带电体的电场分布的方法,能帮助学生把抽象的物理概念建立起直观的物理图像,更好地理解物理知识,加强学生解决实际问题的能力。

By using finite length of equally-charged straight line segments composed of characters---GDOU （ the acronym Guangdong Ocean University）, finding the plane electric field of each electrified segments, and super＇posing these fields, a mathematical model was established in this paper. Then through visual C＋＋ software programming graphical presentation and the visualization research of its field, an exceptionally beautiful curved surface of the electric field distribution. Through this research, we can not only better grasp the calculation methods of the electric field distribution of a finite length charged body, but also understand the powerful drawing capabilities of the use of Visual C＋＋ , which can help students transform the abstract concepts of physics into vivid physical image. Then a better understanding of the physics can be achieved, and the students＇ability to solve practical problems can be enhanced.
