John Hildebrand: The hypothesis that we're putting forward is that the shift downward in frequency is a response to the increasing population of the animals.

约翰·希尔德布兰：我们所提出的假说是声音频率下降是对蓝鲸数量增加的响应。

For each impulse response waveform, FFT is applied in order to get their frequency characteristics.

最后对此平均频率特性实施IFFT以获取系统的脉冲响应。

The simulated results reveal that the stability of the converter is independent of the load current and the input voltage.

并且由于这种新的频率补偿为环路提供了极高的带宽，所以该转换器具有优异的动态响应。

Accordingly, the R1 that manipulates small block value is OK the voltaic pulse of intromit C1 is opposite bigger, such, circuit can is opposite input signal extent dash forward add make faster response, namely " rise quickly " answer.

在低频至中频规模内，只有比较器的输入偏移误差会影响检测器的整体精度。在高频时，比较器的响应时候成为一个首要身分，它会降低 VOUT精度，特别是当频率增添时，情况会更糟。

RESULTS The trend of dynamic frequency response of piezoelectric coagulation corresponded with the inverse S curve F =（f0-△f）＋△f/1＋e^（t-t0）/dtderived from theory according to the change regularity of the viscosity and density in the reaction system.

结果 根据反应体系黏度密度变化规律，理论推导出体外凝血反应过程，中压电频率动态响应规律符合F=（f0-△f）＋△f/1＋e^（t-t0）/dt等‰模型；根据该模型建立了新的反S拟合曲线法；与既有的最大拟合曲率法相比，前者检测速度更快（P〈0.01），重复性更好（P〈0.01）。

The other problem in seismic inversion is that the frequency information and amplitude real value recorded by seismograph are incomplete and severely absent.

地震波反演的另一个障碍，主要是所记录的地震波响应中频率信息及相应的振幅真值的不完整与严重缺失。

The influence of laminated core and winding on the natural frequencies and modal shapes of the stator are investigated.

预测电机的振动和噪声需准确计算电机定子结构的固有频率及定子的响应特性。

Second, we estimate the channel response on data subcarriers using linear interpolation in the frequency domain.

其次我们在频率域上使用线性内插法来得到在资料载波上的通道响应。

The analytical expressions of modal damping and frequency, logarithmic decrement and dynamic magnification factor, which represent the dynamic properties of the system, were obtained by theoretical analyses.

分析表明，Alford力会促进正向涡动而抑制反向涡动，增大正、反向涡动的模态频率，降低正向涡动的稳定性，而提高或降低反向涡动的稳定性则取决于系统的相对阻尼，增大或减小系统的动力放大系数则取决于比转速，并改变系统响应的相位。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
