摘要
多体相互作用系统中的物体平衡状态稳定性问题通常涉及复杂的微分方程难以解析。我们在研究一个由多个点电荷组成的系统中的电荷受到特定扰动后能否回到原来的平衡状态时,通过分析系统各部分之间的作用,建立空间中的电势能场函数,借助软件Matlab进行数值模拟计算其势能和势能梯度并据此绘制出势能可视化图像与势能梯度图像,简明地判断系统各部分的平衡状态稳定性可能性。
The stability problem of the equilibrium state of a body in a multi-body interaction system usually involves complex differential equations,which are difficult to analyze.To study whether the charge in a system composed of multiple point charges can return to the original equilibrium state after a specific disturbance,the electric potential energy field function in the space is established by analyzing the effect of each component in the system.Matlab software is used to carry out numerical simulation to calculate its potential energy and potential energy gradient,and draw the potential energy visualization image and potential energy gradient image.Therefore,the stability of the equilibrium state of each part of the system is simply judged in this way.
