In the last part of the article applications of space cubic ph to sweep surface modeling and pipe surface modeling are introduced , and sufficient criteria that guarantee that the offset of a sweeping surface are generated by the offset curves of the profile curve is investigated
最后，本文介绍了空间三次ph曲线在扫曲面和管道面造型方面的应用，并研究了一扫曲面的等距面为该扫曲面轮廓线的等距线所生成的充分条件。
