ph曲线 meaning in Chinese
ph curve
Examples
- This paper present a sufficient and necessary condition of constructing quintic ph curves and analyze the geometric meaning of the control polygon
本文给出了构成五次ph曲线的充要条件，分析了其控制多边形的几何意义。 - Firstly explicit algorithm is found that give the unique cubic ph that solves a geometric hermite interpolation problem
首先本文给出了三次ph曲线g ~ 1hermite插值问题的算法，这个算法是用复数形式表示的，使插值公式比较简单。 - Quartic ph curves are studied . their contribution of cusps and inflections are discussed in this paper . a first - order hermite interpolation by quartic ph curves is obtained
文中还研究了四次ph曲线，讨论了其尖点和拐点的分布情况，得出了四次ph曲线的一阶hermite插值的解。 - If the geometric hermite data is from a smooth function with the arc - length parametric , the cubic ph approximates the smooth function , the error in the approximation of a short segment of length h is found
如果此三次ph曲线插值于以弧长为参数的某一函数曲线，则可以给出三次ph曲线逼近该一小段曲线的逼近误差。 - Pythagorean hodographs exhibit remarkably attractive properties for practical use . for example , their arc length is expressive as a polynomial function of the parameter , and their offsets are rational curves
Ph曲线呈现出非常优良的实际应用价值，例如它的弧长可表示为曲线参数的一个多项式函数，其等距线是有理的。
