First, a simple discussion for the mechanism about electrostatic atomization of the liquids has been given ; then the paper theoretically analyzed waving course, liquid drop producing course, and the liquid drop diffusing course in electrostatics atomization process., gave an analysis about the methods about carrying charges to the liquid drop, and analyzed that liquid with high electrical conductivity can be carried charges and atomized by electric field, while the isolated liquid with low electrical conductivity can be charged fully with the soakage electrode and inducing charge methods. at last the paper designed and configured the experimental equipment, conducted the atomization experiment to the three liquid medium - kerosene, emulsifier and alcohol under the same environment, handled the experimental results, then summarized the relationship between liquid electrostatic atomization effect and liquid surface tension, electronic conductivity and viscosity, along with the influence of voltage to electrostatic atomization and so on, found out the liquid atomization rule in high voltage electrostatic field

區;然後對液體荷電方法進行了研究分析，對于高電導率的液體，場致荷電和接觸荷電可以使其霧化，而對于電導率較低的絕緣液體，需用浸潤電極荷電和感應荷電方法使其充分帶電;最後，根據前面的研究分析，設計和組裝試驗裝置，在同一環境下對
煤油、乳化劑、酒精三種不同液體介質進行高壓靜電霧化試驗，並對試驗結果進行分析處理，總結出液體靜電霧化與液體表面張力、電導率和粘度的關系及電壓對液體靜電霧化的影響等，得出高壓靜電場中液體霧化的一般規律。
