  “杂交曲线”译为未确定词的双语例句
     The cleaved DNA was separated by pulsed field gel electrophoresis (PFGE) and Southern blotted with the probe p13E 11. The sizes of EcoRⅠ fragments were calculated by "curve fitting" according to the MidRange PFG marker and the alleles were assigned to their respective chromosomes based on their BlnⅠ sensitivity. Data were analyzed using a commercially available statistical package (Version 11.0 SPSS).

This paper presents a new approach to approximate rational curves with polynomial curves by perturbation method.The coeffcients of a rational curve under Bernstein bases is disturbed so as to get a polynomial curve,and such that the perturbation is minimized in L 2 norm.By constraining the perturbation it is possible to make the perturbed curve have certain order of contact with the rational curve at the two end points.This results can be combined with subdivision method to obtain a continuous piecewise...

This paper presents a new approach to approximate rational curves with polynomial curves by perturbation method.The coeffcients of a rational curve under Bernstein bases is disturbed so as to get a polynomial curve,and such that the perturbation is minimized in L 2 norm.By constraining the perturbation it is possible to make the perturbed curve have certain order of contact with the rational curve at the two end points.This results can be combined with subdivision method to obtain a continuous piecewise polynomial approximation for a rational curve.Examples confirm that the approximation method presented in this paper is generally better than that of Hermite interpolation and hybrid curve approximation.

利用曲线摄动的思想给出了用多项式曲线逼近有理曲线的一种新方法.其基本步骤是对有理曲线的控制顶点进行摄动,使之产生一多项式曲线,并使摄动误差在某种范数意义之下达到最小.同时,通过适当控制摄动曲线的顶点,使逼近多项式曲线与有理曲线在两端点保持一定的连续性.这一结果可以与细分(subdivision)技术结合给出有理曲线的整体光滑的分片多项式逼近.实例表明,在某些情况下本文中的方法要优于传统的Hermite插值方法及T.W.Sederberg和M.Kakimoto(1991)提出的杂交曲线逼近算法.

In this paper, by using the perturbation theory, A new approach is presented to approximate rational curves with the interval Bz ier curves. First of all the coefficients of a rational curve are perturbed und er the Bernstein bases so as to get a polynomial curve, and such that the perturbed rat ional curve is minimized in the L 2 norm.

In this paper, by using the perturbation theory, A new approach is presented to approximate rational curves with the interval Bz ier curves. First of all the coefficients of a rational curve are perturbed und er the Bernstein bases so as to get a polynomial curve, and such that the perturbed rat ional curve is minimized in the L 2 norm. Then by solving the maximal cont rol points, a perturbed rational curve is obtained which is contained inside an interval Bzier curve. Because the L 2 norm is used, the method shown in t his paper allows more restriction to the perturbed rational curve, su ch as smoothness restriction. Therefore the interval Bzier curve and its conta ining approximation curve can be used to interpolate the rat ional curve at the two end points. Such interpolation can be kept in a certain order of smoothness. By the application of the well known subdivision approach to this method, in a continuous piecewise polynomial can be obtained which appro xim ates the rational curve with certain global continuation, and a piecewise interv al Bzier curve which also approximates the rational curve with certain globa l continuation and interpolates the rational curve at the end points. Finally, s ome examples are given to show that the the met hod used to approximate the rational curve is generally better than Hermite inte rpolation and hybrid curve approximation.
