抜粋

Extensive Kerr electro-optic field mapping and voltage/current measurements have been taken with highly purified water over the temperature range of T equals 0-30 degree C using parallel plane electrodes with average field strengths up to 160kV/cm. The Kerr constant of water B was measured to be B approximately equals 3. 4-3. 6 multiplied by 10** minus **1**4m/V**2 for free space light wavelength of 590nm and only slightly varies with temperature over the measurement range. For a step high voltage, there is no volume space charge at t equals O// plus . For times greater than 500 mu s, stainless steel and copper electrodes generally inject positive charge, although under some conditions with mixed electrodes they injected negative charge; aluminum electrodes only inject negative charge; while brass electrodes can inject either positive or negative charge. Thus, by appropriate choice of electrode material combinations and voltage polarity, it is possible to have uncharged water, unipolar charged negative or positive, or bipolar charged water.
