样条插值曲线 meaning in Chinese
spline
Examples
- Extending the cubic a - b - spline interpolation curves with the blending function of degree 4 ( 3 - b ) , we get the interpolation curves of degree 4 . the curves have not only kept the structures and properties of the cubic a - b - spline interpolation curves but also increased a shape control parameter , which expands the adjusting ranges of the curves and make the curves easier to be controlled
利用三b四次调配函数对三次- b样条插值曲线进行了扩展，扩展后得到的四次插值曲线在保留了三次- b样条插值曲线的结构和性质的同时，增加了一个形状调节参数，从而扩大了参数对曲线的调节范围，使曲线更易于控制。 - As a result , the curves of c3 and c4 continuity can be generated , and the shape of the curves can be adjusted by the parameters x . the quadratic non - uniform b - spline curves are further extended and the continuity of curves is improved in this paper ; with a local shape parameter in each piecewise curve , the shape of the curves can be controlled effectively ; moreover , cusps of curves can be generated conveniently on the curves while using multiple knots
对二次非均匀b样条作了进一步扩展，提高了曲线的连续性；曲线的每一段上都有一个局部控制参数，利用它们可以更有效的控制曲线的形状；同时，利用曲线的重节点可以很方便的在曲线上构造尖点。作为b样条扩展曲线的应用，作者将上面构造的各次调配函数应用到三次- b样条插值曲线上，得到下述结果。 - By using auto - adjusting boundary conditions and the method of three cubed spline curve fitting , the system software can recover both of the horizontal and vertical beam profile . the measurement system can also measure the beam landing screen error of cpt . it provides a important measurement and analysis tool to improve the performance of electron gun and dy , and improve the definition of cpt
系统软件中，提出了采用动态确定边界条件，通过对离散采样点的三次样条插值曲线的拟合恢复束斑x和y方向的轮廓，本系统既能准确客观地描述电子束轮廓，又能够准确快速地测量电子束着屏误差等多种参数，为cpt电子枪和偏转系统的性能改进与分辨率的提高提供了有力的测试分析和研究手段。 - As further expansion of the cubic a - b - spline interpolation curves , in order to raise the continuity of the curves even , the author has defined the blending functions of corresponding degrees , constructed the adjustable interpolation curves of degree 5 and degree 6 with polynomial blending functions of degree 5 ( 3 - b ) and degree 6 ( 3 - b ) respectively . they are c3 and c4 continuous separately
作为三次- b样条插值曲线的进一步扩展，也为了提高插值曲线的连续性，作者定义了相应次数的奇异调配函数，同时利用三b五次、三b六次调配函数分别构造了五次和六次参数可调的插值曲线，它们分别是c ~ 3和c ~ 4连续的。
