When the governing valve was series - connected on the return oil - line in the metering - out control system, under the same flow area and the same adjusted pressure of relief valve, with the incremental quantity of step load, the pressure highly - adjusted capacity of the hydraulic cylinder chamber with piston - rod increased, meanwhile, it ' s time of rise, time to peak and the governing time all increased. at the same time, the pressure highly - adjusted capacity of the hydraulic cylinder chamber without piston - rod increased
當出口節流調速系統的回油路上串接調速閥時，隨階躍負載的增加，在相同流量閥開度、相同溢流閥調節壓力的情況下，液壓缸有桿腔壓力p _ 2 （ t ）的超調量是增加的，上升時間、峰值時間以及調整時間也是增加的；液壓缸無桿腔壓力p _ 1 （ t ）的超調量是增加的。Accorded to the experimental research, under different flow area of flow valve and different adjusted pressure of relief valve, conclusion that the regulation of the pressure p1, p2 in the two cylinder chambers varied with the change of step load were as follows : when the throttle valve was series - connected on the return oil - line in the metering - out control system, under the same flow area and the same adjusted pressure of relief valve, with the incremental quantity of step load, the pressure highly - adjusted capacity of the hydraulic cylinder chamber with piston - rod decreased, meanwhile, it ' s time of rise, time to peak and the governing time all decreased. while the pressure highly - adjusted capacity of the hydraulic cylinder chamber without piston - rod increased
通過試驗研究得出系統在不同的流量閥開度、不同溢流閥調節壓力（進口壓力）下，液壓缸兩腔壓力p _ 1 、 p _ 2隨階躍負載變化的規律：當出口節流調速系統的回油路上串接節流閥時，隨階躍負載的增加，在相同流量閥開度、相同溢流閥調節壓力的情況下，液壓缸有桿腔壓力p _ 2 （ t ）的超調量是減小的，上升時間、峰值時間以及調整時間也是減小的；液壓缸無桿腔壓力p _ 1 （ t ）的超調量是增加的。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。
