Study of Phenomena of Streaming Electrification in Dielectric Liquids utilizing Kerr Electrooptic Measurement of Electric Field Vector Distribution

1.我们开发了一种测量随时间变化的电场分布的光学系统。通过对系统的改进，可以对600 μ s范围内的电场分布进行时间序列分析。当一个DC。对球对球电极系统施加电压，测量了电极系统中某些区域的连续电场分布。随着时间的推移，测得的电场分布受到干扰。造成这种扰动的原因可能是液体由于移动电荷而移动。对带电介质液体中的电场矢量分布进行了测量。很明显，测量到的光强数据必须加以修正。利用校正后的光强数据，重构了电场矢量分布。电场强度比未充电时小。自制了一套流致电系统。利用该系统，证实了液体流动时电荷的存在。并获得了系统的一些基本数据。

1.We developed an optical system for the measurement of electric field distributions changing with time. By the improving the system, time series analysis in 600 μ s of electric field distribution became possible. When a DC.voltage was applied to a sphere-to-sphere electrode system, continuous electric field distributions on some areas in the electrode system were measured. In the course of time, measured electric field distribution was disturbed. The cause of this disturbance might be that the liquids moved because of moving charge.2.The measurement of electric field vector distribution was carried out in the dielectric liquid forced to charge. It became clear that the measured light intensity data must be corrected. By the corrected light intensity data, the electric field vector distribution was reconstructed. The electric field strength was smaller than that without charging.3.A system to generate streaming electrification was manufactured by oneself. Using the system, the existence of electric charge caused by flowing a liquid was confirmed. And, some elementary data for the system were obtained.
