  • discontinuity point

例句与用法

  • In the second part of the thesis , we consider a one - dimensional dynamical system with only one discontinuous - critical point and prove that the set of periodic points is uniform hyperbolic if such a map is globally expanding . han shuguang ( dynamic system & ergodic theory ) directed by prof . cao yongluo
    本文第二部分对具有唯一临界间断点的一维映射的动力学性质进行了探讨,利用最大单调区间的办法,由映射的整体扩张性证明了映射的周期点集的一致双曲性。
  • Because ec is simple and it seldom needs any additional information about the problem , ec becomes a general solver of challenge problems . according to the essential property of the discontinuous function , we design a new hybrid coding structure - - point - tree structure , which uses a point to present a discontinuity and a tree to present a sub - function
    我们根据间断参函数识别问题的本质特征? ?间断性,设计了一种新的复合编码结构? ?点树结构,用点来表示间断点信息,用树来表示子函数信息,通过对点和树的联合演化来达到寻求最优解的目的。
  • Finally , a new 3d surface ranging method based on a digital fringe projection and shifting technique is systematically studied and non - linear rectification algorithms which reduce measurement error is proposed . at the same time , the noise - immune phase unwrapping algorithm is deeply studied and a new algorithm for phase unwrapping of phase map is proposed . experiment make known the algorithm can reduce measurement error , bypass the noise points automatically , solve the problem of the shade sheltering or cavity , overcome the error propagation problem and better results have been obtained
    论文最后系统研究了基于数字相移条纹投影曲面三维测量方法,创造性地提出了一种减小测量误差的非线性校正算法,取得了预期的效果;同时对相位去包裹算法进行了较深入研究,提出了一种噪声图像相位去包裹方法;实验表明该方法能减小非线性测量误差,自动避开噪声点和间断点,获得了满意的结果。
  • Furthermore , the dq value ranges of profile multifarctal spectra in different landform types and in different directions of the same sections perform different properties and anisotrpies . it can be concluded that the landscape fractal properties depends closely on the int ensity , manner and inhomogenity of exogenic and inogenic processess , and with the properties , we can study quantatively the dynamic geomorphic process . by using the same methods just above , local fractal dimensions d , crossover length tc and the multifractal spectra dq - q of two large - scale landform profiles ( across and along tianshan mountain ranges respectively ) are calculated . the results show that in the studied scaling range the two profiles perform different scaling properties , and both of them can be divided to three evident different linear scaling subsections
    不同类型地貌区二维地貌表面也表现出多度域分形特征,而且随着观测尺度的增加,每个区间的分维值均表现为依次减小,表明外营力作用的影响逐渐被内营力作用所取代:不同类型地貌区在相应区间的分维值表现为高山区中低山区盆地区,体现了不同类型地貌表面粗糙性或复杂性的差异,因此分维值大小可作为地貌表面外营力侵蚀作用强度的重要指标:利用标度区的间断点和各种地貌类型表面分维值或宏观效应趋于一致,提出5 - 6km左右可作为地貌的宏观临界点,并且与利用地貌剖线研究所得到的5km这一数值是基本吻合的。
