Chaikin algorithm is the simplest discrete curve modeling method.In thepaper planar Chaikin algorithm is generalized into sphere,and the practicability ofthe algorithm as well as the continuous differentiable property of the generatingcurve is proved.It is shown that the curve generated by Chaikin algorithm is apiecewise spherical Bezier curve of second kind of order two.Furthermore,generalspherical corner-cutting algorithms are discussed,and it is pointed out that thecurve generated through corner-cutting has"Spherical Variation DiminishingProperty".3Curve interpolation method restricted on a smooth surface based ontransformation.

Chaikin算法是最简单的离散曲线造型方法，文中将Chaikin算法推广到球面，证明了算法的可行性和生成曲线的连续可微性，指出球面Chaikin算法得到的曲线是分段的二次第二类球面Bezier曲线，并给出了用球面Chaikin算法构造球面插值曲线的算法；进一步，文中讨论了一般的球面割角算法，指出由球面割角算法得到的曲线具有"球面变差缩减性质"。3基于变换的约束在光滑曲面上的曲线插值方法。

因此提高果蔬产品的质量，发展贮藏加工业，是我国果蔬产业发展亟待解决的问题。1 目前我国果蔬产业发展中存在的问题自 1993年以来，我国果品产量跃居世界第 1位，成为世界第一大水果生产国，但是长期以来由于重视产量，忽视质量，重视采前增产措施，忽视采后处理、贮藏加工，造成果蔬产品采后腐烂变质严重，损耗极大，这些问题主要表现在以下几个方面：1.1 果蔬产品品种结构不合理我国的果蔬产品产量虽高，但质量较差，市场售价低，品种结构不合理，早熟、中熟、晚熟品种比例不当，非凡是没有适于加工的优质品种，明显制约了我国果品加工业的发展。
