为了补偿一个固定保护电极和一个活动保护电极的垂直可计算交叉电容器的端部效应误差，世界各国主要测量机构通常采用两种不同的方法，一种是鼻形件法，另一种是改进的有源辅助电极法。然而，后者的电气方法将有一些困难，组装的法布里-珀罗激光干涉仪的谐振腔的反射镜。本文介绍了一种能满足光学要求的新型空心有源辅助电极，模型实验结果表明，它具有与改性有源辅助电极相似的优良补偿效果。
In order to compensate the end-effect error in the vertical calculable cross-capacitor with one fixed and one movable guard electrodes, two different methods including the nosepiece and the modified active auxiliary electrode are usually adopted in the main worldwide national measurement institutes. However, the latter electrical approach will have some difficulties in assembling the mirrors for the resonant cavity of Fabry-Perot laser interferometer. This paper describes one novel hollow active auxiliary electrode which can satisfy the optical requirements and the model experimental results show that it has similar excellent compensation effect with the modified active auxiliary electrode.
