  1. The numerical results of the dispersion relation show some nonlinear effects : for a fixed geometry of a waveguid, beam parameters and plasma density, the increment of the modulation parameter may lead to a slight increment of the operating frequency, however, as the modulation parameter increases further, saturation may occur and the dispersion relations are hard to be separated, it is due to the overmodulation of the microwave power, this phenomenon itself belongs to the nonlinear effects

    對於一定的波導、電子注參量和等離子體密度值，等離子體調制系數的增加，使工作頻率略微升高。但是，隨著等離子體調制系數的進一步增加，色散曲線變得彼此之間不可分辨，可以認為是等離子體的過調制導致了柵的飽和。這一現象是非線性的，可見，等離子體柵和調制場中文摘要是非線性關系，等離子體柵是非線性j 。
  2. On the following, on the basis of formulas given above, three kinds of effects due to ionosphere are presented : image shift due to group delay which was caused by the difference between the group velocity and the velocity of light in the ionosphere ; image distortion due to ionospheric dispersion which can create second phase error of lfm signals ; the last, the phase perturbation caused by the irregularities of the ionosphere can reduce the coherent length and affect azimuthal resolution

    文中主要研究了電離層的三種影響：信號經過電離層傳播的群延遲引起的成像偏移；電離層的色散效應給線性調頻信號帶來二次相位誤差，導致圖像退化、失真；以及電離層的閃爍、湍流等不規則性引起的信號相位起伏。在此基礎上，比較分析了不同波段、帶寬條件下電離層的影響。
  3. In addition to showing the solution to linear qd and its analysis, one form of nonlinear qd is discussed. compared with other color diffusion techniques, considering the interactions between channel pairs, qd has the following advantages : 1 staircasing effect is avoided ; 2 as diffusion tensor, the image derivative is regularized without requiring additional convolution ; 3 less time is needed. experimental results demonstrate the effectiveness of linear and nonlinear qd applied to natural color images for denoising by both visual and quantitative evaluations

    雖然講四元數用於圖像處理已有了一些研究，但都是研究四元數傅立葉分析四元數小波分析或將簡化的四元數偏微分方程用於灰度圖像處理，而本文第一次將四元數擴散用於顏色圖像處理，這樣的好處包括： 1可以避免一般非線性擴散的階梯效應2四元數擴散不需要對圖像導數進行高斯卷積等歸整化操作3更為省時。
