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。 -
As the bases of the proposed transform coefficients are very close, the transform normalization can be implemented only on the encoder side and the dequantization table size can be reduced compared with the transform used in h. 264 mpeg - 4 avc. along with the feature of the proposed transform, adaptive dead - zone quantization optimization for the proposed transform is studied

The main features of the system are as follows : ( 1 ) there is no direct mechanical connection between engine and wheel, so the engine can be adjusted to work at high efficiency zone. ( 2 ) the power of the engine can be transmitted to driving axle directly by the electromagnetic force, and only part of power is converted from mechanical energy into electric energy, so the power losses in energy conversion can be reduced. ( 3 ) the system can also operate as electronic continuously variable transmission
