  1. On the base, we designed the waveguides " structure and fabrication parameter. and in the design of symmetric y - branch of proton - exchange s ingle - y phase linbo3 modulaor, we used finite difference beam propagation method to analyze and compare the optical transmission loss of different s - bend y - branch

    本文對質子交換linbo _ 3單y相位調制器的重要部件y分支進行了深入的研究，比較了不同s彎曲形式的y分支過渡長度與損耗的關系，並計算出間距250 m時的最小彎曲長度。
  2. The details of the construction and characteristics of the new finite - difference scheme are presented in this thesis, by using both the integration theorem and the taylor expansion theory. it is proved that the new approach has the second - order accuracy on the grids with axis - symmetric voronoi cells and at least has the first - order accuracy in general. according to this character of the scheme and the computational requirements of the finite - difference approach, a striping procedure is involved to decompose the velocity model into variable spatial size grids with a nearly constant tune step preserved

    本文從積分定理和taylor展開兩個角度，詳細分析了基於voronoicell的非規則網格有限差分演算法的構造過程及性質，並且在理論上證明了本文的差分方法的精度與網格形狀的關系：當voronoicell為關于節點的軸對稱圖形時，本文差分方法具有二階精度；在一般的網格上，則至少具有一階精度。
  3. Let f is a circularly symmetric function, with constructing a positive real function and using integral method, the difference of the modular of successive coefficients of k symmetric functions of circularly symmetric functions is also obtained, which is a sharp estimate

    當f為園對稱函數， = 1 / k （ k = 2 ， 3 ， … ）時，通過構造一個正實部函數，利用積分方法，得到了k次圓對稱函數相鄰系數模之差的精確估計。
