| 摘 要： | 把平面介质和点电荷目标作为一个整体系统,利用镜像法研究了平面分层介质对点电荷目标静电场的影响,推算出像电荷在系统中的位置表达式,并根据两种介质中像电荷的电量公式推算出三层介质中像电荷的电量计算表达式.建立了平面介质被动式静电探测系统的物理模型,给出探测电极所在空间电场强度的计算公式.采用"旋转电极"的方法和静电感应原理进行目标探测,确定被动式静电探测器的探测方程,并使用静电计和仿真模型进行了试验,证明了该静电探测技术的可行性.

| Abstract: | The plane medium and point charge are regarded as an integral system. The influence of layered plane medium on the electrostatic field of point charge target is investigated, and the position expression of the image charge is given. The charge amount calculation expression of the image charge in three layered mediums is reckoned based on the formula of the image charge in two layered mediums. The physics model of the passive electrostatic detection system in the plane medium is built. The calculation formula of the electric intensity in the space where the detection electrode is placed is given. The method of "circumrotate electrode" and electrostatic induction principle is used to detect the target. The detection equation of the passive electrostatic detector is confirmed, and the feasibility is proved by simple examination. |
