In this thesis, used thermocouple to sense the temperature in the space of the hearth, attributed the thermocouple based on calorifics and scientific arithmetic, acquired data by data acquiring card, processed data according to the demand of setting up temperature model and drawing graphics and then caculated the coordinates of isothermal points and normals of isothermal facets, ascertained the order of connecting points and the model of construct, drawed the isothermal facet of temperature field with opengl at last
通過數據採集板卡進行數據採集並與計算機介面進行數據處理。然後，將處理后特殊點的溫度數據依據marchingcubes演算法建立數學模型求取等溫面上的點的坐標及各點的法向量等。最後，確定計算的三維坐標點的連接順序和拓撲模型，利用opengl進行等溫面的繪制、消隱和模式變換等工作。4 - intersection theory in point set topology is cited into time domain and topological relation between several temporal forms are analyzed in detail. besides, the paper uses temporal topological relation to describe cadastral changing process particularly
把點集拓撲學中的四元組理論引用到了時間域中，詳細地分析了幾種時間形式之間的拓撲關系，用四元組描述的時態拓撲關系對地籍變更過程進行了詳細的描述。The conception of financial ecology provides a new research method for finance - the essential motivity of economics. it emphasizes the system view of financial field and the unfinancial field concerned as whole and the financial risk concerned with the financial external surroundings. the financial field is faced with complete opening from china affiliated to wto, and it takes rigorous test to our financial ecology
在本文的研究中，運用了系統論、信息論的觀點和拓撲學的方法，通過構建金融生態中信息的響應函數和資源配置的結果函數，建立從金融生態的系統空間到信息空間，再到資源配置空間的映射，分析金融生態中的信息集中和信息分散的過程，從宏觀的運行機制上研究金融生態的信息效率問題。Stzware is a two and three dimension spatial analysis software based on realms math model developed by nuaa, and the two - dimension subset of this software defines spatial data types on 2 - dimension discrete grid, such as point set ( privpoints ), line set ( privlines ) and region set ( privregions ), and implements attribute operation functions of these 3 types and topology analysis functions among these 3 types
Stzware是由南京航空航天大學研製的基於數學模型realms的二三維空間分析軟體，其中的二維子集定義了二維平面離散網格上的空間數據類型:點集（ privpoints ） 、線集（ privlines ）和區域集（ privregions ） ，並實現了這三種類型的屬性操作函數和這三種類型間的拓撲分析函數。In section 2, we study the fixed point, stable set and unstable set of this system. for given parameters a trapping region is found with the property that any interval of unstable set will be expand under the map, so we get the conclusion that the system has infinitely many homoclinic orbits. as a consequence of the previous conclusion, we discuss the attractor of the system
在本文中，我們討論了一個分段線性模型，它是物理學中用來模擬r - l - diode電路行為的數學方程，通過研究，我們得到該系統的一些拓撲性質以及符號動力學中的一些結論，主要內容如下：在第二節中，我們對給定的參數值，通過數值計算研究了該系統的不動點，不動點附近的穩定集與不穩定集，發現該系統中存在一個捕捉區域：該區域中的不穩定流形總體上是擴張的。分享友人
