peak asymmetry 中文意思是什麼
peak asymmetry
解釋
峰不對稱性-
Asymmetric profiles of tip clearance have little influence on rotor peak efficiency, and the degree of degredation is in rat io of the level of asymmetry at circumferentioal direction
轉子尖部間隙周向布局的變化對失速裕度及效率的變化起負面影響，且隨著周向變化的程度加大，這個惡化趨勢也加大，但對峰值效率的影響較小。 -
Agrawal ' s theory model of soa ca n ' t simulate accurately the amplified signal pulse shape in soa when the pulse width is as short as several picosecond. so we simulate accurately the peak power, full width half maximum, rising time and falling time of amplified pulse after considering the gain compression, gain asymmetry, gain shift, gain variable with situation and time. with ultrahigh velocity dense wavelength division multiplexing ( dwdm ) and optical time division multiplexing ( otdm ) developing, we demand more and more short signal pulse and more signal channels
但當信號脈沖的寬度只有幾個皮秒時， soa傳統的agrawal理論模型已經不能完全準確地模擬soa對信號脈沖的放大情況，在此基礎上，我們在全面考慮soa的增益壓縮、增益非對稱和漂移、增益隨位置和時間變化的載流子壽命等物理機制的情況下，對皮秒超短高斯信號光脈沖經soa放大后的脈沖的峰值功率、脈沖半值全寬度、脈沖的上升時間和下降時間等重要物理參量進行了準確模擬和詳細研究。
