摘　　要：现有本科物理实验教材中电流场模拟静电场项目原理部分大多与无限长同轴柱状导体为例,讲解长直导线周围存在的静电场与两比较,其中的证明过程难理解,运算复杂,偏离了实验教学的初衷,将学生的很多时间花费在实验过程证明的理解和运算中,不利于实验教学的开展。针对以上问题,结合实验设备结构,将实验原理中的证明过程以平行板电容器内部静电场以及平行板间电流场为例,讲解模拟法的实验思想、测量原理和应用条件,证明过程简单明了,与仪器结构精密结合,更加有利于学生加深对电场强度和电势概念的理解。Existing undergraduate physics experiment teaching ma-terial in the current field simulation principle of electrostatic field projects mostly with infinite coaxial cylindrical conductor,for exam-ple on long straight wire electrostatic field around compared with two,proof that the process is hard to understand,the operation is complex,deviated from the original intention of the experimental teaching,the students spend a lot of time in the experiment proves that the process of understanding and operation,is not conducive tothe experimental teaching.In view of the above problem,this paper combined with the experiment equipment structure,the experiment principle of proof process in parallel plate capacitor internal static electric field and current field between parallel plate as an example explain simulation experiment thought,measuring principle andapplication conditions,proof process simple and clear,with preci-sion instrument structure,more conducive to the students to deepen understanding of the concept of electric field strength and electric potential.
