Let f be a biquadratic polynomial , then ( 1 ) the julia set of f is connected if and only if the orbits of all critical pionts are bounded ; ( 2 ) the julia set of f is totally disconnected if and only if every connected component of the filled julia set of f containing critical points is not periodic under iterations : ( 3 ) if f does not satisfy the conditions ( 1 ) and ( 2 ) , then the julia set of f has infinitely many non - trivial connected components , where a component is trivial if it contains only one point A集是完全不连通的当且仅当f的任何临界声、不属于填充julm集的周期分支内。你当j的临界卢、不满足条件小, ” j时, f的几ha集有可数个非平凡的连通分支,这里,一个分支是平凡的,如果它仅由一个卢、组成。 。
Abstract : according to the deformation or fracture caused by uneven loads on the structural connection , the smart structure with sensible and regulative functions has been proposed to be used in bolt groups . the smart structure is constituted with the auto - even - load connecting component made of the shape memory alloy material . the mechanical behavior of the auto - even - load component in the bolt groups is analyszed . its auto - even - load and the regulative principle to prevent the fracture are also studied 文摘:本文针对结构联接受力不均易产生变形或破裂等问题,提出了在螺栓组中加装由形状记忆合金材料制作的自动均载传力件构成具有感知和调节功能的智能结构,并对螺栓组联接加装均载传力件后的均载防断功能进行了力学特性分析,特别是对螺栓组传力件自动均载和防断的调节原理进行了研究,最后进行了实验验证。
In this paper , we first give some sufficient conditions for t in a tree t : theorem4 . 1 : let d be a set of t , if the vertices of d are all hooks and each middle vertex of t relative to d has only one neighbor in d , then ji = y , ? theorem4 . 2 : let d be a yrset of t , if the vertices of d are all hooks and the connected components of [ d ] : d1 , d2 , . . . . . . , 首先这篇文章给出了在树中_ l与_ t相等的一些充分条件:定理4 . 1 :设d是树t的_ t集合,若d中每点都是钩子,且t关于d的每个中介点都只与[ d ]的一个连通分支相关联,则_ l = _ t 。
The principle of this approach is : during the second alphabetically pixel scanning of the labeling algorithm , the first pixel of each connected components is found , and a start - point table used for contour following is set up based on certain principles , thus the operation of search start points of the contour in the image is avoided , the execution of the standard contour following algorithm is accelerated 算法的基本原理是:利用标记过程寻找连通区域中第一个像素出现的位置,在此基础上根据一定原则确定轮廓起点,省略了在图像中逐像素搜索轮廓起点的过程,达到加速算法执行的目的。
In the paper , the connectivity and diameters of sell - complementary 2 - multigraphs and sell - complementary digraphs are discussed , and if these graphs get disrupted the relations for the number ob edges and vertices between the two connected components are also studied in self - complementary permutation 摘要本文讨论了2 -重自补图和有向自补图的连通性以及2 -重自补图的直径,同时以自补置换作为工具研究了当2 -重自补图或有向自补图被分成两个连通分支后,这两个连通分支之间的边数与顶点数之间的关系。
