  2. The results show that wavelength locates in gain zone of semiconductor optical amplifier, and have higher peak power and proper time delay between the two pulses for the second order super gauss control pulse in semiconductor optical amplifier. a high quality amplified signal pulse can be achieved. the chirp can be reduced notability by using cascading soa in cross gain modulation based on soa, and the distance and the peak power of conversion optical pulse can be increased notability, and we can let down the demand for wavelength based on xgm in soa and enhance the flexibility of wavelength conversion

    我們應用二階超高斯光脈沖與高斯信號脈沖同時注入soa和應用soa與非線性光學環鏡（ nolm ）相結合的方案來對信號脈沖進行壓縮整形，模擬顯示，在調節系統合適參數的情況下，波長位於soa增益區的二階超高斯控制光脈沖在具有較高的峰值功率和適當時延下輸入soa時，最後可以得到放大的高質量超簡訊號光脈沖；在基於soa的交叉增益調制（ xgm ）全光波長轉換中，採用級聯的soa能有效地使反轉光脈沖的頻率啁啾得到有效降低，波長向下轉換的距離和反轉光的峰值能量都得到明顯提高，降低了利用交叉增益調制（ xgm ）波長轉換中對波長精度的要求，從而提高了波長轉換的靈和性。
  3. A solid - liquid fluidized bed has been designed and installed, which will be used in the heat exchanging and descale field. the experimental study for distributor design was carried out and the particles distribution in the tubes of the solid - liquid fluidized bed under different operating conditions was studied by using the ccd measure system. experimental results show that heterogeneous pores distributor which was arranged in the inlet chamber of the solid - liquid fluidized bed can improve the nonuniform distribution of particles in the pipe bundle under high flow rate. the nonuniform decreases by decreasing the mount of pore, but the solid holdup decreases too. the particles distribution is influenced by the position of the heterogeneous pores distributor

    實驗結果表明：在液固循環流化床進口段安裝可調節高度的變孔徑分佈板，能在較高的流速下，較好的改善固體顆粒在管束中的不均勻分佈；開孔率越小固體顆粒在管束中的分佈越均勻，但管束中粒子的平均固含率也越小；分佈板的安裝高度對顆粒的分佈有很大的影響，在實驗范圍內分佈板的安裝距離管束入口處越遠，顆粒在管束中的分佈越均勻。
  4. After analyzing the theory of mtdi and setting up the model of moving target echoes, the dissertation discusses in detail the effect of moving target doppler center frequency and doppler rate on the conventional sar image. it also analyzes detailedly the range migration of moving target from time field and frequency field and provides migration model in both fields. after that, it divides algorithms of mtdi into several classes, analyzes the influence of signal - to - noise on the detection results and gives the flow chart of moving target imaging processing
