In the interface of gas and dielectric liquid phases, while the phenomenon in this research aiming at analysis and an elucidation generated weak electric discharge in the gaseous phase, it was one electrohydrodynamic(EHD) phenomenon in which a liquid flowed. In the experiment, the convenience technology of the particle image velocimetry(PIV) was applied to the molecular tagging velocimetry(MTV). While developing the flow velocity measurement technology of the EHD ionic flow field of gas-liquid two-phase fluid, a quantity of amounts of electric charges and drift speed of the charged particle were turned, and the knowledge about electrical conductivity effect was acquired.

在气体和电介质液相的界面中，虽然本研究中的现象旨在分析和说明在气相中产生的微弱放电，但它是一种液体流动的电流体动力学（EHD）现象。本实验将粒子图像测速技术（PIV）的便捷性应用于分子标记测速技术（MTV）。在发展气液两相流体EHD离子流场流速测量技术的同时，对带电粒子的电荷量和漂移速度进行了量化，获得了有关电导效应的知识。
