【摘要】 对各种不同形式电极在不同电场条件下影响蒸馏水蒸发的因素进行实验研究,电场由线电极、针电极和板电极分别和接地板电极形成,不同电场条件通过改变电极距离、电场方向等实现。实验结果发现:相同电极接负电压形成的电场对蒸馏水蒸发的促进作用优于接正电压和交流电压的情况,针电极接负电压产生的电场对促进蒸馏水的蒸发效果要优于线电极或者板电极接负电压的情况。以上这些实验说明:电场的方向、电极的形式以及电极之间的距离是影响电场下蒸馏水蒸发的重要因素。更多还原

【Abstract】 This article studied influencing factors of evaporation of distilled water under different types of electrode and different conditions of electrostatic field. The electrostatic fields were formed by a line electrode, a needle electrode, a board electrode, respectively. By changing the distances between electrodes and changing the directions of electrostatic fields, different conditions of electrostatic field were gained. When the same electrodes were connected with negative voltage, the promotion of evaporation was better than which connected with positive voltage or alternating voltage. When the needle electrode was connected with negative voltage, the promotion of evaporation was better than that when the other two types of electrodes were connected with negative. So we can obtain that directions of electrostatic field and types of electrode are important factors, which affect the evaporation of distilled water. The result has some guiding significance in designing drying equipment using electrostatic field.更多还原
