-
摘要: 本文主要分析了B样条曲线的特点及边界条件,通过三次样条插值与三次B样条曲线逼近两类数学模型在土工试验微机普图中的曲线对比,说明了三次B样条曲线应用的优点。Abstract: This paper mainly analyses the characters and boundary conditions of B-spline curve, and demonstrates the advantages of tke cubic B-spline curve in the computer drawing of soil test curves through comparing the curves drawn by computer for two kinds of mathematical mode between the cubic spline curve and cubic B-spline curve.
