织物静电电位分布测量仪的研制

研制了织物静电电位分布测量仪,由高灵敏度电压传感器、信号放大器、数据采集卡、扫描控制系统组成,可对织物或其他片状物的静电压分布进行检测。采用可视化人机对话操作界面,可实现扫描、测量及数据采集,特别适合于含导电纤维纺织品经摩擦后的静电电位分布曲线的检测,可从静电分布规律入手进行抗静电机理研究和抗静电纺织品的设计。

Some Optical Properties of an Electrostatic Quadra-pole with Circular Concave Electrodes

In the present work, an ideal Quadra-pole field has been realized by circular concave electrodes with a proper electrode angle The potential distribution in such an electrode system has been analyzed by assuming a simple boundary condition. The effect of the gap angle between the electrodes of the Quadra-pole lens on the optical properties has been studied such as the focal lengths, magnification and the chromatic aberration coefficient in the convergence and divergence planes.
