、原理稳恒电流场的电势与静电场的电势满足相同的偏微分方程，当稳恒电流场与静电场有相似的边界条件时，稳恒电流场的电势分布与静电场的电势分布相同。因此，可用二维稳恒电流场来模拟二维静电场。二、特点和用途该仪器采用镀有半导体透明导电膜的普通玻璃板作为平面型...
In principle, the potential of the steady current field and the potential of the electrostatic field satisfy the same partial differential equation. When the steady current field and the electrostatic field have similar boundary conditions, the potential distribution of the steady current field is the same as that of the electrostatic field. Therefore, a two-dimensional stable current field can be used to simulate a two-dimensional electrostatic field. Second, characteristics and use The instrument uses a common glass plate coated with a transparent conductive film ...
