摘　　要：本文分析了一个电势参考点选取问题,即在同一个物理系统中,先选一点为参考点建立基本关系式,再选另一点为参考点得到所需结果,选用不同的参考点,并不改变电势表达式中变量项的形式,因而不影响电场的分布。This paper analyzes the choice of reference points for electric potential,namely choosing one point as the reference point to establish a basic relational expression and choosing another point within the same physical system as the reference point to get another result.The results show that the choice of different reference points does not change the form of the variable in the electric potential expression,hence not the distribution of the electric field either.

关 键 词：电势 参考点 变量项
