However, operating of the high current, the output power, gain, and efficiency of gyro-TWT will be degraded where the absolute instability, gyrotron backward oscillation and reflective oscillation occur to cause mode competition. Stability issues comprise the key factors limiting the performance of the gyro-TWT.

對於高電流的影響亚洲v欧美v日韩Ⅴ中文字幕，磁旋行波放大器將有可能引發(fā)絕對不穩(wěn)定波多野结衣性爱视频、磁旋返波振蕩(gyrotron backward oscillation；gyro-BWO)及反射振蕩99超碰碰，造成模式競爭而抑制原先操作模式的放大波国产精品免费一区二区久久，進(jìn)而影響其輸出功率、增益及效率自拍人人爱人人操。

However, operating of the high current, the output power, gain, and efficiency of gyro-TWT will be degraded where the absolute instability, gyrotron backward oscillation and reflective oscillation occur to cause mode competition. Stability issues comprise the key factors limiting the performance of the gyro-TWT, therefore physical origins of spontaneous oscillations in the gyro-TWT are analyzed and characterized.

然而受限於操作高電流国产精品99久久精品2020，磁旋行波放大器可能引發(fā)絕對不穩(wěn)定性、磁旋返波振蕩(gyrotron backward oscillation狼友视频在线免费播放；gyro-BWO)及反射振蕩张津瑜落地窗国贸，造成模式競爭而抑制原先操作模式的放大波，進(jìn)而影響其輸出功率清纯激情欧美、增益及效率欧美日韩色一区二区三区视频。

In the research on the backward-wave oscillation suppression the startoscillation current which is derived from Two-wave theory approximately is given up. Four typical un-uniform slow wave structures start-oscillation current equations are derived by backward-wave amplifing gain expressions with the Two-wave theory. Then the start-oscillation current rates I〓/I〓 between ununiform circuit and uniform circuit of the four structures have been got.

在返波抑制問題的研究中，從二波理論出發(fā)在线高清无码黄片，拋棄了二波理論中從起振條件出發(fā)來得到起振電流近似表達(dá)式的方法性爱小视频欧美，而是利用二波理論的基本關(guān)系式分別推導(dǎo)出了四種典型實(shí)用的非均勻輸出線路的返波增益表達(dá)式，采用計算返波增益的方法來得到四種非均勻輸出線路的起振電流與均勻輸出線路起振電流的比值I〓/I〓https黄视在线。
