计算机模拟静电场

Mock Electrostatic Field with Computer

电学中的许多复杂的概念 ,是肉眼所看不到的 ,这就造成学习上的一定困难。如对于描述静电场的电力线。如能利用计算机来描绘电力线 ,给出场强分布情况的直观图象 ,对于学习掌握电场性质会有较大的帮助。本文根据“电力线是正电荷沿着电场的方向连续地作微小移动时描绘出的轨迹”的思想 ,利用

Many complicated concepts in electricity is invisible to naked eye,which cause difficulties to study.For example,the lines of electric force used in the description of ecletrostatic field.It will be large useful for studying and grasping the nature of a electric field,to describe the lines of electric force with computer and saw the direct picture on the distributing situation of a field's strength.This paper is a program desing in QBASIC depend on the idea that'the lines of electric force are the orbits which a straight charge is moved along the direction which it is forced in the field
