研究了不同电压下的窄脉冲荷电,利用密立根油滴仪测量了有无导流柱情况下的液滴荷电量.研究表明,无导流柱的情况下,窄脉冲放电电压低于火花放电电压时,随着电压的增加,气溶胶颗粒的荷电电量也随之增加,当电压达到火花放电电压时,窄脉冲放电的荷电量最大,但当所应用电压大于火花放电电压时,荷电量反而下降.应用导流柱时,可以避免流注放电中等离子区内的电中和,所以应用的电压大于火花放电时,应用导流柱的情况下,气溶胶颗粒的荷电量大于无导流柱时的电压,但当电压低于火花放电电压时,导流柱的应用则不利于气溶胶颗粒荷电.同时也研究了导流柱直径对荷电量的影响,指出导流的直径为2cm时最有利于窄脉冲荷电.研究为以后窄脉冲荷电的应用提供了依据.
Experiments of charging particles by short-pulse discharges were carried out under different voltages and the charge number on drops was measured by Millikan cell with and without a diversion cylinder. The results show that without the diversion cylinder, the charge number on drops increases with the increase of the voltage, while both the short-pulse voltages are lower than the broken-down voltage. The charge number on drops reaches the maximum when the short-pulse voltage is equal to the broken-down voltage. But when the short-pulse voltage is higher than broken-down voltage, the charge number on drops is decreased. However, when the diversion cylinder is present, the neutralization phenomenon could be avoided in the plasma region. The charge number on drops is higher than that in case without the diversion cylinder. But it is not beneficial to charging to use the diversion cylinder when the applied voltages are lower than the broken-down voltage. At the same time, the influence of the cylinder diameter on the charging on drops is studied and it is indicated that it is the best for charging of the short-pulse discharge when the diameter of the diversion cylinder is 2cm.
