查询词典 amplitude

It is found that the change of the frequency characteristics of chaotic system occurs mainly at the frequency band of the chaotic system, in which the input signal exists. The amplitude of the input signal doesn't influence the distortion of the output signal when masking signal is extracted by Oppenheim's chaotic masking.

研究发现，混沌系统频率特性的变化主要发生在输入信号的频率位於混沌系统频带内的情况下；输入信号幅度的大小，不影响输出信号的失真。

The results show that the change of modulation period and modulation depth affect the period of soliton interaction and the difference of relative amplitude barely affects period of soliton interaction. In particular the lattice soliton interaction is effectively avoided by opposite phase soliton.

结果表明：调制周期和调制深度的变化影响了格子孤子相互作用的周期大小，而相对振幅的差异对孤子相互作用的周期影响较小，特别是反相孤子能够有效控制格子孤子的相互作用。

Active noise control is achieved by introducing a canceling "anti-noise"wave of equal amplitude and opposite phase using a secondary source.

主动消声是利用声波之间的相消性干涉原理，使声场局部区域声能相互抵消，从而达到降低噪声的目的。

Base on the principle of the superposition of waves, active noise control and active vibration control is achieved by adaptively tuning a secondary source which produces an anti-noise of equal amplitude and opposite phase with primary source.

主动噪音控制及主动振动控制籍由适应性地调适第二控制点，使第二控制点产生与主要声源或振源大小相等、相位相反的干涉波，而得以实现噪音消除及振动抑制之目的。

Base on the principle of the superposition of waves, active noise control and active vibration control is achieved by adaptively tuning a secondary source which produces an anti-noise of equal amplitude and opposite phase with primary source.

Results Compared with the signals during relaxation, the eletromyographic signals of orbicularis oculi muscle during contraction became significantly larger at amplitude.

可以通过对眼轮匝肌肌电信号实时分析的方法，监控眼轮匝肌的功能状态，从而监控闭眼动作的发生。

In addition, genes can oscillate with different amplitude — the swing between the highest and the lowest point.

此外，基因可以摆不同幅度的摆动中最高和最低点。

Proceeding from their oscillation differential equation, meeting the position conditions of borders and jointures between adjacent parts, this paper deducts the amplitude expressions of each part of whole system, and makes the stationary wave chart.

从微分方程出发，利用边界条件和各部分之间的连接条件，本文建立了超声传递系统各组成部分的振幅方程，得到驻波波形图。

Finally, the so called critical oscillation frequency can be expressed as a function of oscillation amplitude and Grashof number in all the natural, mixed, and forced convection scenes.
