查询词典 amplitude contraction

In Amplitude Analysis in time domain, the step impulse response acts as an important parameter to evaluate the performance of audio device. It reflects the response sensitivity of audio system to sudden changed signals.

在音频设备的时域特性分析中，阶跃脉冲响应检测是衡量系统性能的重要方法，它反映的是音频设备对于突变信号的响应灵敏度。

To avoid or reduce re-analysis, we derived the augmentative matrix variation only in summation of the previous matrices time the outside-perturbed parameters by decomposing the element stiffness and mass matrix. The implicit function of amplitude about design variables such as cross-areas and lengths is changed into simplistic function about the perturbed parameters of design variables. Several methods for determining the value of perturbed parameters are detailed.

为避免或减少重分析，将有限元单元阵进行了分解变换组装，使振幅与设计变量如截面面积、长度的复杂隐函数关系转化为对设计变量摄动参数的显式关系，进而将设计变量摄动参数提取在分解后的几个常数刚度阵、质量阵之外，避免了在迭代求解过程中重组刚度阵与质量阵，较快地获得问题的解。

The simulation results show that the average error in synchronization exhibits a nonmonotonic behavior with the noise amplitude.

数值模拟结果表明平均同步误差与噪声强度之间的关系是非线性的。

By mean of averaging method, the amplitude-frequency response equations in steady state are obtained.

采用平均法对主共振问题进行了求解，得到了稳态运动下的幅频响应方程。

在数值模拟中可以看到随观测方位和入射角变化的纵波振幅和旅行时的差异。

The value of the area is direct proportional to the number of baffler and the parameter of free area ratio, but it increases exponentially with the diameter of the column and the pulsed amplitude.

峰面积值与脉冲萃取柱的板数和板开孔率参数成正比，与柱径和脉冲振幅成指数关系。

The nonlinear error can be eliminated by adjusting the amplitude of modulated current in accordance with the beat frequency.
