In this paper, we have made a systemic theoretic research on modelling and reshaping several types of spline curves/surfaces in CAGD. And some creative productions are given as follows. At first, the uniform C-B-spline basis is proved to be a normalized totally positive basis, and can be extended to a normalized B-basis. C-B-spline and C-Bézier basis, similar to B-spline basis and Bézier basis in algebraic space, are two bases in algebraic trigonometric space.

本文围绕着CAGD中常用的几种曲线曲面造型和形状调整进行了深入的研究,主要获得了以下一些成果:首先,证明了代数三角空间中的n次均匀C-B-spline基是一组标准全正基,并进一步扩充为一组标准B基。C-B-spline基与C-Bézier基是多项式与三角混合空间中的两组基,是适应工程实践中设计特殊曲线曲面的需要而产生的,类似于多项式空间中的B-spline基与Bézier基,是CAGD中重要的造型工具。

The paper is devoted to the quartic invariant algebraic curves in quadratic system.

本文在给定参数满足一定的条件下,研究了一类二次系统的四次不变代数曲线系统平衡点的稳定性态,并运用Dulac函数法给出了该系统不存在极限环的充分条件,这一研究在同类问题中具有一定的拓展性。
