This isi series oscillation has following characters : ( 1 ) long term cycle duration, whose duration of most oscillations ranged from 3 0 - 120ms, so we called it slow wave oscillation ; ( 2 ) large amplitude of oscillation, the minimum isi is about 2ms while the maximum is beyond 40ms, which suggested that the firing frequency vary from several tens to hundred hz ; ( 3 ) abrupt turn always occurs during the continuous change in isi, this turn is called inflexion temporarily
該振蕩波有下述特徵： （ 1 ）振蕩周期較長，多數在30 ? 120s范圍，故稱慢波振蕩； （ 2 ）振蕩幅度較大，其isi振蕩最小值在zms左右，最大值可達40ms ，表明放電頻率可在幾十到幾百k范圍內變動； （ 3 ）在isi連續變化過程中往往出現突然轉折，暫稱其為拐點。 -
Numerical studies suggest that long scale and slow - changed oscillations in the zonal wind stress rebuild by pop anal ysis make the intention of el nino / la nina events deeply. it also enlarges their range. but, positive and negative anomaly center is toward west than actual conditions
數值試驗的結果表明，由pop重建的緯向風應力中緩慢變化的大尺度振蕩成分加深了elnino lanina事件的強度，加大了它們的空間分佈范圍，但正負距平中心的位置比觀測風應力模擬的情況偏西。 -
However, by comparison with flap nozzle servo valve which has been used widely and popularly by now, the torque motor of jet pipe servo valve has a larger rotary inertia. this causes low natural frequency of servo valve, and thus the response speed of jet pipe servo valve is slow. moreover, the jet pipe of servo valve has large flexibility, and it is easy to excite oscillations and noise in the valve, which is named self - excited oscillations and noise
然而與目前普遍使用的噴嘴擋板伺服閥相比，射流管伺服閥的銜鐵組件轉動慣量大，導致力矩馬達部分固有頻率低，從而響應速度慢，此外，射流管供油管柔性大，容易產生自激現象，這些缺點都使得射流管伺服閥的動態特性差，從而影響了它的工作性能。
