摘　　要：针对球形电容器小偏心距的情形,通过求解拉普拉斯方程得到偏心球形电容器内的电势分布,再由场强分布研究偏心距对球形电容器耐压能力的影响。研究结论不仅能解决该电容器电场的计算问题,分析其内部电场分布规律,而且还可为提高球形电容器的加工制作精度提供理论依据。对提高球形电容器的质量,定量计算实际生产中出现的工艺偏差具有一定的参考价值。The potential distribution of small eccentricity spherical capacitor is obtained by solving Laplace's equation,and get the effect of the voltage ability of an eccentric spherical capacitor on the eccentricity through field intensity distribution. The conclusion of this study can not only solve the computational problem of this kind of electric field and assist the analysis of its internal electric field distribution,but also can provide theoretical basis for the general manufacture of precision cylindrical capacitors. Besides,it can improve the quality of an eccentric spherical capacitors. And it is valuable for quantitative calculation of the actual production process when variation occurs.
