| 摘 要： | 运用经典电磁学理论结合能带论的方法讨论了静电屏蔽效应，认为静电屏蔽效应是静电场屏蔽效应．而不是静电势即静电能量的屏蔽效应。计算了静电平衡状态下导体的静电能量；分析了计算的方法；讨论了静电能量与静电场能量的意义与区别。通过计算处于静电平衡状态导体球的静电能和静电场能，计算了带电薄层的厚度并讨论了薄层厚度的意义

| 关 键 词： | 静电屏蔽效应 静电平衡状态 静电能量 静电场能量 |

| Abstract: | We discuss electrostatic screening effect by applying the classic electromagnetism theory combined with energy band theory, considering electrostatic screening effect as electrostatic field screening effect, instead of the electrostatic potential, i.e. electrostatic energy, screening effect, we calculate the electrostatic energy of conductor ir the stare of electrostatic balance, and analyze the way of calculating, discuss the difference between and the meaning of electrostatic energy and electrostatic field energy,and measure the thickness of charged sheet and to discuss the meaning of the sheet＇s thickness by calculating the electrostatic energy and electrostatic field energy of conductor sphere in the state of electrostatic balance. |

| Keywords: | electrostatic screening effect the state of electrostatic balance electrostatic energy electrostatic field energy |
