periodic curves
解釋
周期曲線-
Therefore, it can be used as an efficient new model for geometric design in the fields of cad / cam. at last, the spatial definition of periodic spline and natural spline constructed by polynomial and hyperbolic functions is given ; the dimension law and zero properties are demonstrated ; and therefore the non - uniform algebraic - hyperbolic period and natural spline curves are obtained. the applications of the low order are given in details
三、給出代數雙曲周期樣條及自然樣條空間定義,證明其維數定理和零點定理,構造具有最小緊支撐的非均勻代數雙曲周期及自然樣條函數,進而定義非均勻代數雙曲周期及自然樣條曲線,最後具體給出低階的表示和應用
