扰动频率 meaning in Chinese
disturbance frequency
Examples
- Large eddy simulation of rectangular jets on the effects of various inlet disturbance frequencies
入口扰动频率对矩形射流影响的大涡模拟 - The reynolds number of the flow is 3000 . the circumferential wave number of psb disturbance is 1 . the frequency of disturbance is 0 . 5
本文计算中流动的雷诺数选定为3000 ， psb扰动的周向波数选定为1 ，扰动频率选定为0 . 5 ，扰动宽度选定为。 - It is studied that the formation mechanism of taylor bubble and its control method in gas - liquid two - phase flow , which affects the pressure balance and mechanical driving efficiency in the flow of petroleum engineering . experiments show that the formation of taylor bubble in gas - liquid two - phase flow is due to the intensive congregation and amalgamation of small bubbles driven by void fraction waves and that the highly turbulent flow is able to restrain this formation . thus , the flow regime transition may be checked by increasing the flow turbulence and controlling the disturbed frequency
对大管径气-液两相流动中严重影响压力平衡与机械驱动效率的段塞流生成机制和控制方法进行了研究，实验证明段塞流的形成是由于空隙率波的大幅度增长使气泡高度集中，并形成聚并所致。强湍流运动可以抑制taylor泡的形成。因此，通过强化湍流或控制扰动频率可以对气泡聚并起明显的抑制作用。 - In this paper periodically perturbed hopf bifurcation to lienard equation with limited time delay is sdudied in detail . that is , the influence of small periodic perturbations on system exhibiting hopf bifurcation is sdudied . in particular , the excitation frequency and the critical natural frequency of hopf bifurcation in the cases of harmonic resonance . subharmonic resonance , ultraharmonic resonance , and ultrasubharmonic resonance is discussed . it is shown that in some parameter regions the sestyms exhibit harmonic solution bifurcation , subharmonic solution bifurcation , ultraharmonic solution bifurcation , ultrasubharmonic solution bifurcation and quasi - periodic solution
本文详细研究了具有限时滞li nard方程的周期扰动hopf分支，即在该系统经历hopf分支时，研究小周期扰动对系统的影响，特别是讨论了扰动频率与hopf分支周期解的固有频率在共振、次调和共振、超调和共振、超次调和共振的情形。
