抑制器

A general form of D-FOG has been proposed in order to lower the bias drift and several forms of that have been studied:(1) The Blake type in which a depolarizer is inserted between the polarizer and coil-coupler of D-FOG can suppress the intensity error but not change the magnitude order of the amplitude error.(2) The type with two Lyot depolarizers added in the ends of sensing coil can suppress efficiently the both errors.

为了减小D-FOG漂移，作者提出去偏陀螺的一般形式，并分析其中几种重要形式：（1）在偏振器与环分束器之间插入Lyot去偏器的Blake形式，可以有效地降低强度误差但不改变振幅误差的量级；（2）在传感环两端各插入一个去偏器可以有效地抑制这两种误差。

The power variation of the targeted harmonic signal and harmonic suppression ratio were calculated and evaluated. The theoretical caculations and simulated results suggest that power variation can be maintained within 1 dB with dc bias drift less than 5% and the harmonic suppression ratio is stable in the SSB RoF link.

理论计算和仿真结果表明，偏置漂移会使目标信号的功率抖动增大，但当偏置漂移量小于5％时，功率抖动小于1 dB，而谐波抑制比保持稳定；分析了与非理想光电调制器啁啾相关的有限消光比和双臂驱动不平衡度对RoF链路性能的影响，有限消光比会增加目标信号的功率抖动并降低谐波抑制比，而通过优化调制器的双臂驱动不平衡度可以提高单边带调制RoF链路性能。

The most heavy flow ability of barrage swirl is controlled by fastenning device and barrage size, the most heavy discharge is more when barrage aperture is bigger, the influence of barrage position on discharge is not obvious; The pressure of the end of the shaft and fastenning device increases which aroused by barrage, and there is a restraining action to flow waving of the shaft; The barrage aperture is smaller, the increase of pressure is heavier, the influence of position to the increase of pressure is not obvious; The positive pressure of the level section in the hole between fastenning device and barrage increases obviously, the change of press along length reduces, mural press in the hydrosphere separating area of outlet of fastenning device becomes positive pressure, which is propitious to the increase of flow cavitate number in the low pressure area of the outlet of fastenning device; The influence of change of swirl cavum diameter caused by barrage to ventilating state is obvious.

阻塞旋流最大泄流能力由起旋器及阻塞体型共同控制，降低了泄洪洞的泄流量，孔径大的阻塞最大下泄流量较大，阻塞位置对泄流量的影响不明显；阻塞引起竖井及起旋器端头压力增大，对竖井部分的水流波动具有抑制作用；阻塞孔径越小，压力增加越大，位置对压力增大影响不明显；起旋器与阻塞之间水平洞段的止压力明显增加，沿程压力变化减小，起旋器出口的水气分离区壁面压力变为正压力，有利于起旋器出口低压区水流空化数的提高；阻塞引起的旋流空腔直径变化对通气状态产生明显影响。
