摘　　要：本文研究了高压静电场电压变化对密闭容器内培养皿中水分蒸发的影响,并与无电场作用的试验对照组做对比。试验结果表明,在异端极距为200mm,静电场对水分蒸发同时有促进和抑制作用,试验前期密闭容器内温度降低,湿度增大,静电场的促蒸作用大于抑蒸作用。当放电一段时间后,容器内温湿度达到一定程度时,静电场的抑蒸作用使得容器内湿度降低,温度有所回升,而且电场的电压越大,密闭容器内温度越低,湿度越高而且变化的越快,蒸发量也越大。In this paper the author investagited the effects of the changing voltage of high voltage electrostatic field（HVEF） on evaporation of water inside of the Petri dishes in the sealed container, and contrast with the matched group without effect of HVEF. The result of experiment show that HVEF have the role of promote and inhibit on evaporation of water at the same time when the distance of electrode is 200mm, temperature was fell and humidity was increased in the sealed container when earlier stage of experiment and the promote effect on evaporation of HVEF was greater than inhibit effect. After discharged a period of time ,the humidity reached a certain extent, humidity was reduced and temperature was rose by the inhibit effect of HVEF. When the voltage of HVEF charged, the temperature was lower and the humidity was higher , the evaporation also became bigger in the sealed container.
