本论文介绍一种通过已知的电多极子电势来计算更高阶电多极子的电势及电场强度计算方法，该方法采用了更为简单的数学技巧，即以已知的电多极子为基准，通过坐标变换后将新构造的电多极子的电势用已知电多极子的电势来表征.传统的电多极子电势和电场强度计算方法通常依赖于复杂的数学运算和繁琐的推导过程，限制了其在实际应用中的灵活性和效率，同时也不利于数学知识不足的低年级学生学习理解.本计算方法物理图像清晰，也可以帮助加深对电偶极子及电偶极矩物理本质的理解.

This paper presents a method for calculating the potentials and electric field strengths of higher-order electric multipoles based on known electric multipole potentials. The method employs simpler mathematical techniques by using known multipoles as a reference. Through coordinate transformation, the potential of newly constructed electric multipoles is expressed in terms of the known multipole potentials. Traditional methods for calculating the electric potential and field strength of electric multipoles often rely on complex mathematical operations and cumbersome derivations, limiting their flexibility and efficiency in practical applications. Additionally, such methods pose challenges for lower-level students with limited mathematical knowledge to learn and understand. The proposed calculation method offers a clear physical picture, which also aids in deepening the understanding of the physical nature of electric dipoles and electric dipole moments.
