半值 meaning in Chinese
half value
Examples
- Half - value thickness
半值厚度 - Half - value with
半值宽度 - 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
但当信号脉冲的宽度只有几个皮秒时， soa传统的agrawal理论模型已经不能完全准确地模拟soa对信号脉冲的放大情况，在此基础上，我们在全面考虑soa的增益压缩、增益非对称和漂移、增益随位置和时间变化的载流子寿命等物理机制的情况下，对皮秒超短高斯信号光脉冲经soa放大后的脉冲的峰值功率、脉冲半值全宽度、脉冲的上升时间和下降时间等重要物理参量进行了准确模拟和详细研究。
