英文
first-order tetragonal prism-
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。The fourth chapter is the important chapter of this paper : firstly, this chapter analyzes the total arrangement of the buildings, the single building ' s distribution, the extensibility of the building ' s functions and the design model of " trinity ", we find out that flexibility is the core of the university library design, " trinity " is not the only way and the best way in the library design ; secondly, this diaper raises another design model - - the design of hybrid library, in which the array of pillars, the level height and the load are designed according to the subarea, this design method can improve the flexibility and ecnomization of the buildings ; at last, this chapter approaches the principles and the developing trend in the design of the university library
第四章是本論文的重點章節，在這一章中，論文首先從建築總體布局、建築單體布局、建築功能的可擴展性、 「三統一」的設計模式等方面進行了細致的分析。我們發現：靈活性是目前我國高校圖書館建築設計的核心問題； 「三統一」並不是圖書館建築設計的唯一方式和最佳方式，於是提出了一種分區設計柱網、分區設計層高、分區設計荷載的另一種設計模式? ?復合式圖書館建築設計，旨在增加靈活性的同時，進一步提高建築的經濟性與實用性。在章節的最後，從宏觀上探討了高校圖書館建築的設計原則及發展趨勢。The fma need the high order hankel function, in chapter 3 the algorithm of calculating the high order hankel function of the second kind is discussed. because of the low effectivity and unsteadiness to use the recursive algorithm to calculate the high order hankel function of the second kind, the paper introduces a kind of new fast algorithm to solve the problem. the worked result indicates : the new fast algorithm is a kind of precise algorithm
由於快速多極子法計算中要用到高階漢克爾函數，在第三章中，主要針對利用遞推演算法求解高階漢克爾函數時速度較慢和可能存在不穩定的問題，給出一種快速計算高階漢克爾函數方法，最後給出了用快速多極子法計算的四個導體柱體散射截面。
