摘要
自制法拉第杯测量装置,测量粉末颗粒在不同直流电晕方式人工荷电时荷电量。试验并分析了测量 的诸多干扰因素及屏蔽问题,采用杯上覆盖接地金属网可有效屏蔽电极等干扰。
An apparatus based on analogous Faraday cup, measuring of the artificial electric quantum of powder particles charged by different direct current poles,is developed by the authors.The different disturb to measurement and shielding are discussed and tested.The interference from static charge can be eliminated effectively by covering the cup with a grounded metal mesh.
