  1. To completely avoid producing elements jointed at their corner nodes and checkerboard patterns, which frequently occur when the topology optimization of plane continuum is studied, the theory of topology analysis of plane continuum in topology optimization process and the simple algorithm for programming are studied. according to algebraic topology theory, the boundary of elements and plane continuum are operated as a one - dimensional complex. by use of the adjacency vector in graph theory, the structural topology is described and the topological operation is achieved on a computer. by above, the structural topological feature in the evolutionary process is gained. these methods are effcient and reliable. under topology constraints, according to the results of stress analysis, by deleting elements and moving nodes at the boundary, more satisfactory results can be gained by using a few numbers of elements and iterations. to demonstrate the efficiency of these methods, solutions including some well - known classical problems are presented

    避免目前平面連續體結構拓撲優化過程中經常出現的單元鉸接以及「棋盤格」等現象，研究了連續體結構拓撲優化過程的拓撲分析方法，以及在計算機上實現的簡便演算法.根據代數拓撲理論，單元及連續體的邊界作為1 -復形進行運算.利用圖論中的鄰接向量概念，在計算機上實現了結構的拓撲描述及拓撲運算，得到了結構在拓撲演化過程中的拓撲特性，方法簡單、可靠.在一定的拓撲約束下，根據應力分析結果，採用刪除單元、單元退化、移動節點等方法，可以用較少單元得到更為滿意的結果，提高計算效率.為演示方法的有效性，給出幾個包括常見經典問題的解答
  2. Aimed at that error may occur in feature - editing, feature - editing is researched, based on the topological mapping algorithms, the function of feature editing is implemented

    針對特徵編輯參中常會出現的不合理結果，藉助于標識匹配演算法，設計並實現了特徵編輯演算法，可較為合理地實現特徵編輯。
  3. The distinct feature of this approach is to reconstruct the 3d model of target from images progressively in accordance with the general modeling conventions. namely, user firstly determines the rough model and puts projection and spatial constraints on it as well as topological operations step by step to let the system recover the camera parameters and refine the model

    該方法的主要特點在於，按照一般人的建模習慣，由粗到細地通過圖像重建目標三維模型，在確定大致形狀的基礎上，由用戶添加或者修改投影約束與空間約束，並施加拓撲修改，逐步實現照相機定標，粗糙模型的求精，並最終完成對具有任意幾何及拓撲物體的重建。
  4. Physical feature - dependent topological simplification and data compression of planar vector fields

    與物理特徵相關的平面向量場的拓撲簡化及壓縮
  5. In feature description, a novel topological relationship set which is composed of six named topological relationships and an inverse operator is defined, and its completeness and exclusiveness are proved. then, a video shot model based on mpeg - 7 standard is constructed and a description scheme to video shot is implemented perfectly

    在特徵描述與建模方面，提出了一種以六類拓撲關系組合逆運算符的新型拓撲關系集合，並證明了其具有完備性和互斥性，在此基礎上建立了一個基於mpeg - 7標準的視頻鏡頭模型，完整地實現了對視頻鏡頭的描述。
