关于液体电介质在非均匀电场作用下的成桥现象

On the liquid bridge formed with dielectrical liquid in a non-uniform electric field

对非均匀电场作用下液体电介质形成的所谓"流体桥"现象进行了研究.通过分析水分子电偶极矩在非均匀电场中的受力情况,解释了流体桥的形成和稳定性,对不同电介质的成桥情况进行了对比研究;在流体内的功能关系中计及电场力的功,即利用含电场项的流体伯努利方程,分析了流体桥中的净质量转移情况,并进行了实验验证.

If a high voltage is applied to a fluid（e, g. deionized water）in two beakers,which are in contact, a fluid bridge may be formed. The formation and stability of the bridge are researched. The various bridges formed with different liquids are investigated. With the help of the Bernoulli equation involving the work of electric force, the mass transfer of the liquid through the bridge is analyzed and researched experimentally
