(1)Measurement of electric field distributionThe Kerr optical method which is developed in measurement of electric filed has been used in this study. Using CT method, we could depict the field map in nitrobenzene for the special plane in which field directions are all the same, but their intensity are not constant along laser path. One of such planes is the plane which is vertical to the center axes of two sphere electrodes at the bisect point. The other plane is one just on the plane electrode countered a sphere electrode. Measured values of field strength includes errors below 10% compared to calculated values.(2)Measurement of electric field vectorOne of 2-dimensional field vectors is appeared between coaxial cylinders. The direction and strength of the vector could be measured within 10% error under pulsed applied fields. To extend the method to 3-dimensional measurement, deference of two refractive indexes, for normal and abnormal light, could be related to field intensity and the angle between the vector and light. A simplified equation for the relation has been found. In 3-dimensional measurement, laser beam was passed through the test cell for directions which was perpendicular to each other. The angle B between the horizontal axis and the projected vector to vertical plane to the laser was measured by the method of 2-dimensional measurement. The vector components of 3-dimensional vector were calculated by two B's. The errors were in the 10 degrees in the direction and 5% in the intensity.The measurements of field vector distribution in 3-dimension should be future work.

(1)电场分布的测量本研究采用了在电场测量中发展起来的克尔光学法。利用CT方法，我们可以在硝基苯中描绘出场方向相同，但场强度沿激光路径不恒定的特殊平面的场图。其中一个平面是垂直于两个球体电极的中心轴在对分点的平面。另一个平面是与球面电极相对的平面电极。场强实测值与计算值的误差小于10%。(2)电场矢量的测量同轴圆柱体之间出现一个二维电场矢量。在脉冲场作用下，矢量方向和强度的测量误差在10%以内。为了将该方法扩展到三维测量，正常光和异常光的两个折射率的差异可以与场强度和矢量与光之间的角度有关。已经找到了这种关系的简化方程。在三维测量中，激光束在相互垂直的方向上穿过测试单元。采用二维测量法测量了水平轴与激光垂直平面投影矢量之间的夹角B。三维矢量的矢量分量由两个B来计算。方向误差为10度，强度误差为5%。三维场矢量分布的测量是今后的工作方向。
