  1. In the first part of the paper, the explicit form of difference equation and periodic boundary condition is derived in cartesian coordinate system. secondly, the dispersive characteristic is analyzed in cylinder coordinate system for many high power microwave devices use cylinder sws. and then the method is extended to calculate the band structure of 2 - d photonic crystal, a modified yee ’ s grid is introduced to calculate the dispersive characteristic in the case of triangular lattice, so that both square lattice and triangular lattice cases can be solved in cartesian coordinate system

    周期電磁結構的一個重要應用就是用作高功率微波器件中的慢波系統，考慮到目前大部分高功率微波器件的慢波系統多採用圓柱周期結構，在論文第四章中，在圓柱坐標系下，給出了差分方程和周期性邊界條件的具體形式，同時編寫程序，分析了milosws ，盤荷慢波結構的色散特性。
  2. A brand new method of grid nodes corresponding is proposed based on 2 - dimensional neighbor node table. 4. coordinate data visualization

    獨立的提出了基於網格點相鄰關系建立二維表格的網格點匹配演算法。
  3. This paper discussed the coordinate transformation method of wgs84 coordinate system to 1954 - beijing gauss grid coordinate. introduced transformation model of wgs84 to beijing 54 and computing method of transformation parameter. according to different model and computing method, computed and compared with the result combine real data

    本文詳細討論了wgs84大地坐標轉換到北京54坐標系下的高斯平面坐標的方法，重點介紹了wgs84和北京54的空間直角坐標的轉換模型及轉換參數的計算方法，並根據不同的模型和計算方法結合實際數據進行計算和結果的比較，認為採用基線向量求解的四參數模型具有較高的轉換精度，分區變換和提高控制點精度也能提高轉換的精度。
  4.
