Firstly a microstrip - fed microstrip patch antenna has been emulated and validated. on the base of this, the multi - band property of sierpinski equilateral triangle and squareness microstrip fractal patch antennas are carefully studied, and the effect of antenna ' s property by the permittivity, the size of patch, the order of the fractal and the decrease of fractal patches is depicted ; secondly on the base of analysis and comparison of performance of microstrip - fed semicircle and rectangle double - band microstrip patch antennas, warranty of dimension curtailment is offered ; finally expansion of band of those antennas above is discussed
在此基礎上，著重分析了微帶線耦合饋電的sierpinski等邊三角形微帶分形貼片天線以及sierpinski方形微帶分形貼片天線的多頻特性，給出了介質參數、貼片尺寸、分形的階數以及減少分形貼片數對微帶線耦合饋電的sierpinki等邊三角和sierpinski方形微帶分形貼片天線特性的影響；其次基於微帶線耦合饋電的半圓雙頻微帶貼片天線和矩形雙頻微帶貼片天線的性能分析和比較，提供了尺寸縮減的依據；最後對以上天線的頻帶擴展進行了探論。 -
On the assumption of ignoring the distortion of thickness, this paper determines the rough shape by the geometric modeling method of equal area developing using mixed mesh cell of triangle and quadrangle for the first time, presents the equal area developing arithmetic of quadrangle - triangle. on the virtual geometric symmetry axis, we puts forward the method of determining the developed coordinate of the point on the base band in the development of using regular quadrangle cell, determines the developed shape of internal structure in plane utilizing point - to - point mapping theory. furthermore, we realize the approximate developing of undeveloped - irregular boundary surface using a few triangle cells
本文結合型號研製中小曲率機翼整體壁板類零件坯料展開課題，基於板料厚向變形忽略不計的先驗假設，首創混合四邊形-三角形網格等面積展開的幾何模擬法確定壁板類零件毛坯外形，給出了混合四邊形-三角形網格等面積展開演算法；提出了虛擬分割線的概念，採用虛擬幾何對稱軸，給出了規整四邊形單元展開基帶上結點的計算方法；採用映射原理和求交演算法確定了壁板內部結構信息的展開定位。 -
Based on the characteristics of the geological exploring data, a method for establishing data model was presented, in which the triangle network was combined with the quadrangle network. at last, the geologic maps needed for geological research were drawn through the gdi ( graphics device interface ) and the 3d visualization system model was established for stratumtous geological body. base on the achievments mentioned above, a software system was developed which can be used independently without relying on any software platform
文中首先介紹了可視化技術以及地質制圖技術的發展，然後對地質構造可視化模型進行了研究，根據地質測量數據的特點，提出了三角形網和四邊形網相結合的數據建模方法，最後通過圖形介面繪制了地質研究所需的地質圖件，構建了層狀地質體三維可視化系統模型，並開發出了可以獨立於任何軟體平臺使用的地質三維可視化軟體系統。 -
