摘要
本文用计算几何学的观点对Ａ．Ａ．Ｂａｌ在前英国航空公司（Ｗａｒｔｏｎ）研制成功的ＣＯＮＳＵＲＦ系统进行分析，证明了这一系统的机身造型曲线具有包络性质、分段性质、变差缩减性质。
In this paper, some geometric properties (envelope, subdivision, variation diminishing, shape control, convexity preservence, etc.) of the rational cubic curve are given, which form the basis of the CONSURF surface lofting program, developed by Ball at the former British Aircraft Corporation (Warton).
