Since these theoretical analyses are based on inviscid potential flow theory, theoretical calculation and computational simulation may complement each other. the hydrodynamics and undulating propulsion of specimens were studied using three dimensional computational fluid dynamics ( cfd ) modeling. the cfd analysis using kinematic model of undulatory dorsal / median fin draws a series of conclusions, which include that the body drag increases significantly with the lateral body oscillation ; the body drag is minimum while the start point of
計算結果表明游動過程中的形體阻力隨側向周期性擺動而增大;當背鰭前端位於身體側向最寬處時，形體阻力具有局部最小值，結論與實驗觀測結果相吻合;在實驗觀測的典型運動參數下，波動面的運動方程中的非對稱因素的出現使推進力增大約1 . 10倍。 -
It is well known that to start oscillation, every electronic oscillator, including of course the laser, must have a gain slightly in excess of the loses.
如所周知，每一個電子振蕩器，當然包括激光器在內，都必須有稍大於損耗的增益才能開始振蕩。 -
Due to applying double beams, the velocity spread is lower because of smaller influence of space charge compared with single beam mig. in the interaction region this beam is easy to start oscillation and reject mode competition effectively
與單注磁控注入槍相比，雙注槍可以提供速度零散小、高束流的電子注，在互作用區更容易起振，且能更好的抑制模式競爭。 -
The simulation results show that to start the oscillation, the length of the resonance cavity must be well matched with the radial span of the cavity ; mismatch of them will greatly affect the microwave development ; the output power of the microwave in rtto is affected by the microwave mode obviously. under the same conditions, the output power for temooi mode is the highest, and its start and saturation time of oscillation are the shortest. the results also show that the output power will decrease with the increase of the size of the extract window ; the operating state of rtto has great close relationship with the operating current, and there exists an optimum current value
結果表明，束電壓一定時，諧振腔腔長和徑向間距必須良好匹配微波才能起振，匹配不佳會極大地影響微波產生；微波模式對微波產生功率影響很大，同等條件下， tem _ （ 001 ）模式的微波功率最高，起振時間和飽和時間最短；微波輸出功率隨提取口的增大而減小； rtto工作狀態與工作電流的大小關系密切，存在一個最佳工作電流值。
