Abstract: The influences of high voltage electrostatic field on the evaporation and boiling point of sea water under different conditions have been researched. The experimental results show that the evaporation rate of sea water under high voltage electrostatic field condition is 1.5 to 2.1 times of that under normal conditions. The boiling point of sea water decreases with the increase of high voltage electrostatic field intensity. According to the experimental phenomena and data analysis,it is found that water molecules are polar ones. Under high voltage electrostatic field conditions,the electric dipole moment can easily be formed. The electric dipole moment can cause the hydrogen bond between water molecules to break down,so as to make the water apt to evaporate. The energy of hydrogen bond breakdown is from internal energy of sea water,but is not converted from electric field energy.

摘要： 研究了不同条件下高压静电场对海水蒸发速率和沸点的影响。实验结果表明：高压静电场下海水蒸发的速率是常态下的1.5~2.1倍；海水沸点随高压静电场强度的增大而降低。由实验现象和数据分析得出：水分子是极性分子，在高压静电场下易形成电偶极矩，电偶极矩使水分子之间的氢键断裂，从而水分更易蒸发；氢键断裂的能量来源于海水的内能，而不是电场能转化而来的能量。
