亚谐波 meaning in English
subharmonic
Examples
- In the part of modulation and demodulation , we analyzed the principles of harmonic mixer , detectors , power dividers / combiners and branch - line couplers
对调制/解调器射频电路部分，包括亚谐波混频器、检波器、功率分配/合成器和分支线耦合器基本原理进行了分析。 - By the method of double - frequency acoustic excitations , experiments were conducted on the influences of phase differences between the fundamental and subharmonic waves upon the " subharmonic resonance " - the nonlinear interaction between the waves
用双频声激励方法，实验研究了剪切流中基波及其亚谐波的相位差对“亚谐共振”非线性过程的影响。 - The results indicate that there is especially a narrow rang of phase difference in which the amplitude of subharmonic waves is notably diminished and that the diminishment is affected by initial amplitudes of the waves
结果表明，有一个狭窄的相位差范围，当相位差的值落入其中时，亚谐波的空间演化受到显著的削弱；而且，相位差的这种影响受基波及亚谐波初始幅值的制约。 - This problem could be resolved by using sub - harmonic mixer ( shm ) . instead of using mmw lo , shm using microwave signal with frequency equals 1 / 2 or 1 / 4 of mmw lo frequency , thus the technical difficulty and cost of mmw system is reduced remarkably
采用亚谐波混频器( sub - harmonicmixer )可将本振频率降为基波频率的1 / 2或1 / 4 ,从而克服了直接采用毫米波本振源带来的困难,降低了射频接收机的技术难度和系统成本。 - According to the finite element method result , the parametric vibration of cables in cable - stayed arch bridge becomes prone to be exhibited . then a model of non - linear parametric excitation vibration coupling the stayed cable and the girder , namely , the mode of cable - stayed beam , is proposed in the thesis . and the nonlinear dynamical
3 、首先利用有限元分析方法,得出了斜拉索发生参数共振的可能,然后建立了斜拉拱桥拉索-桥面耦合参数振动模型,即索-梁组合结构模型,推导了索-梁组合结构非线性运动方程,利用多尺度方法研究斜拉索的参数共振和亚谐波共振,并对稳态解的稳定性进行了分析。
