摘　　要：解析法在计算倒垂孔有效孔径及中心时逐步受到重视。通过对倒垂孔有效孔径的求解过程进行几何分析和理论归纳,提出一种改进的计算倒垂孔有效孔径和中心的解析方法,并给出基于Visual Basic计算机语言的算法框图。根据该方法开发了一套实用性强的计算程序,可以快速、精确地计算有效孔径和中心,并已在工程实际应用中得到验证,取得了良好效果。Through the geometric analysis and theoretical summary on calculating the effective aperture and the center of reversed pendulum hole by analytic method, an improved analytic method for calculating the effective aperture and the center of reversed pendulum hole was presented herein, and the algorithm frame based on Visual Basic language was also proposed. A practical computer program that can quickly and accurately calculate the effective aperture and the center was developed. The actual application has verified that the method and the program are feasible and practical.
