拓扑特征 meaning in Chinese
topological characteristic
Examples
- First , all topological features in the original mesh model are stored , then sort all the edges according to the importance of vertex , finally delete the edges which lead to sliver triangle and which lead to the discontinuity of triangle normal vectors
该算法首先保存原始网格模型中所有顶点的拓扑特征,然后根据顶点的重要度对所有的边进行排序,通过检查是否产生狭长三角形和三角片的法矢是否连续来判断边是否被删除。 - The research work of this dissertation is focused on the network topology of p2p group communication . the major contributions of the dissertation are summarized as follows : 1 . in the light of the characteristics of p2p group communication , we define two graph metrics , rh and rd , to quantify the matching degree between the overlay and the underlay network
本文重点研究针对多媒体传输的p2p组通讯的网络拓扑,论文的创新性工作主要体现在以下几个方面: 1 .针对p2p组通讯的特点,定义了根跳距和根距离两个拓扑特征指标参数来衡量测试拓扑图和底层网络的吻合程度。 - We introduce five topological characteristics and geometry characteristics that are invariant under projective transformation specially perspective projection . the definition of homograph is given by means of these characteristics , and then the recognizing method of the homograph is proposed according to the definition of homograph
接着，根据透视投影不变性提出了5个用来描述多边形形状的拓扑特征和几何特征，这些特征在透视投影下是不变的，以这些特征给出了在透视投影下平面多边形为类似形的定义。 - A real physical system may involve many variables but only one or more of them can be detected by modem data collecting equipment in recent years , the technique of phase space reconstruction is frequently applied to analyse and process time series . its significance is that the topological characteristics such as fractal dimension can be obtained , on the basis of investigation and research about the technique of phase space reconstruction up - to - now , this paper is also devoted to develop a new method for the prombles of detecting deterministic chaos of time series obtained from experimental data
一个实际的系统可能会涉及多个相变量，但在实际问题中只能得到部分相变量的信息，近年来人们发展了相空间重构方法，能够通过单变量信息重构吸引子，这种方法在时间序列分析和处理中得到广泛应用，其意义在于能在拓扑等价意义下恢复吸引子的拓扑特征，本文第三章在国内外有关时间序列的相空间重构研究状况基础上，致力于发展对时间序列进行确定性检验的新方法，即研究时间序列的分布规律和赫斯特指数，并在相空间重构的基础上，提取吸引子的特征指数。 - In this thesis , six topological characteristics and geometry characteristics are proposed that are invariant under affine transformations and axonometric projection . the definition of homograph is given based on these characteristics , and then the recognizing method of the homograph is proposed according to the definition of homograph at the same time
其次，根据仿射不变性提出了6个用来描述多边形形状的拓扑特征和几何特征，这些特征在轴测投影下是不变的，以这些特征为约束条件给出了在轴测投影下类似形的定义。
