得到抑制反电晕收尘电极的基本型式。
A basic shape of collection electrode for restraining back corona has obtained.
将此方法应用到电晕探测过程，实验结果证明了该方法对图像噪声的抑制有效，保持了相机的动态范围。
Application of this method to corona detection, results show that this method is a availability in restraining image noise and keeping the dynamic range of the camera.
动态范围达到60分贝。 电晕现象将受到抑制，饱和电平寄生信号可得到消除。
The dynamic range reached to 60 dB. The blooming is suppressed completely and the saturation-level shading can be removed.
