本文基于库仑定律和场强叠加原理，利用计算机软件VPython 模拟不同电荷分布的静电场，并利用Plotly 软件分析各点电场强度大小; 研究了点电荷和电偶极子在静电场中的运动轨迹及其能量特征，实时三维可视化电偶极子的运动过程，并探究其运动规律.教学实践表明: 基于VPython 和Plotly 的静电场及电荷运动可视化模拟，能使学生更好地理解和灵活运用静电学相关知识，是对传统物理教学的有益补充.

Based on Coulomb’s law and superposition principle of electric field，this paper explores the electrostatic field of point charge and charge system. With the help of computer software VPython，the electrostatic field under various charge distributions is simulated. Data analysis is carried out by Plotly software. In addition，we study the trajectory and energy characteristics of charged particles in the electrostatic field. Also，we visualize electric dipole’s three-dimensionalmotion in the electrostatic field in real-time. Teaching practice indicated that: thesimulating and visualizing electrostatic field and charge movement based on VPython andPlotlyenables students to have a better understanding of electrostatics-related knowledge，which is a useful supplement to the classic physics teaching.
