摘要: 利用分式线性变换分析偏轴圆柱形电容器内的电场分布,通过数学软件MATLAB绘制出其电场线和等势线图,并研究其耐压能力.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,而且还可为一般的圆柱形电容器的加工制作精度提供理论依据,对提高圆柱形电容器的质量,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.

关键词: 偏轴圆柱形电容器, 电场分布, 耐压能力

Abstract: As a complementary of the original paper, additional transformation formulas applicable to the integrals of periodic integrand are deduced. These formulas, as well as their equivalent forms, can be used as a transformation between such integral and corresponding integral with one limit of infinity. Some infinite integrals are evaluated 'in terms of these formulas.

Key words: periodic function, definite integral, transformation
