  1. At first we improve the methods of iris image preprocessing, including an efficient arithmetic of evaluation iris images, an improving method of locating iris, calibrating iris image by the translation of coordinate and the circular shift of code, a eatimate of the background illumination by bicubic spline, and the image enhancement by the dual tree complex wavelet transform. next we designed the recognition arithmetic based on the location of the local maxima of the wavelet transform modulus. in the thesis lots of simulation are performed by means of matlab and visual c + +

    首先改進了虹膜預處理方法，實現了一種快速高效的虹膜質量評價演算法;設計了一種改進的兩步虹膜定位演算法，準確的定位了虹膜的內外邊界;利用坐標轉換和編碼的循環移位實現了對虹膜圖像的配準;利用雙三次樣條函數擬合虹膜圖像背景，去除了非均勻光照對虹膜識別的影響;使用二分樹復數小波方法增強了虹膜圖像的對比度;在識別演算法方面，本文設計了一種「基於小波模極值點位置的虹膜識別演算法」 。
  2. The wavelet multi - analysis is adopted to further understand the microstructure of solids holdup fluctuation, the vivid fingermark images show that it is a fractal and dissipative structure. the low and frequency signals reflect the dilute phase fluctuation behavior and dense phase ( cluster ) fluctuation behavior, respectively. to deep understand the multi - scales characteristic of gas - solids circulating fluidization, the wp decompose methods for obtaining the eigenvalue of gas - solid fluidized bed has been developed. the results show that eigenvalues of different scales are effective for identification of non - uniform and dynamic structure of gas - solid fluidized bed

    小波多分辨分析法得到指紋圖形象地揭示了顆粒濃度脈動的自相似、分叉等具有混沌特徵的微觀結構；小波分解后信號中的低頻和高頻成分分別代表了稀相和密相的脈動行為，小波包分解提取能量特徵值的方法能夠揭示氣固的多尺度特性，不同尺度上的能量特徵值四川大學碩十論文反映了氣固循環流化系統中存在的非均勻動態時空結構。

  5. In section 2. 2, we prove that if the set of arrows in a quiver is not empty, then nq is not semisimple. we construct the nonsovable subalgebra of nq when there is no less than one circle whose length is bigger than one, and there is no loop in quiver q, thus leads to a conclusion that nq is nonsovable. using the index arrays to discuss the operation of necklace word. construct a sovable subalgebra of nq, which is not nilpotent. this shows that nq is not nilpotent provided that there is a cyclic with length bigger than 1

    當箭圖中有長度大於1的循環，且無圈時，構造了n _ q的非可解子代數，從而證明了n _ q是不可解李代數。我們還利用指標數組討論了項鏈字的運算，構造了n _ q的可解非冪零子代數，從而證明了當箭圖中有長度大於1的循環時，項鏈李代數非冪零。在2
