振幅

It uses the constant amplitude property of inphase and quadrature components of these modulations to achieve an improved performance.

它在这些调制信号中使用了同相和正交分量的恒定振幅属性来确保性能的提高。

In turbulent flow the instantaneous velocity at a point will vary about the mean value of ui .

但是在比临界流速更高的流速下波动稳定且振幅加大，引起高度的径向混合。

Twenty sinewaves of different frequencies may be conceptually complex to us, and the output of a symphony orchestra even more so, but to an amplifier both composite signals resolve to a single instantaneous voltage that must be increased in amplitude and presented at low impedance.

二十种不同频率的正弦波可能对我们来说概念上有点复杂，交响乐团的输出会更多，但是对于一个功放来说，混合信号会分解到瞬间电压（瞬间电压必须在振幅中增加，并且在低抗阻中显示。

However, one major limitation of the standard 12-lead ECG is that it lacks of an integral representation of the time and the amplitude information when depicted on the standard recording chart. Physicians need to visually scan all of the 12 leads for significant abnormalities and then integrate the abnormal features in his mind to learn the location and extent of the cardiac abnormality.

由於十二导程心电图是三度空间的心电讯号投射结果，然而传统的心电图所呈现资讯仅限於时间与振幅的二维变化，缺乏时间与空间整体资讯的呈现；以致於判读诊断上，由於欠缺整体资讯呈现，医师需在脑中进行组合辨识，过程较为繁琐，且对某些病症不易以目视判断。

Find that when the intensity of driving current is not much smaller, action potential of the cell oscillates in mode-lock style.

另外还研究了在周期电流驱动下系统的运动，发现在驱动电流振幅不是很小时，系统作锁模运动。

The zero-contours of the real and imaginary parts of complex amplitude are closed curves. The number of intersection points of the zero-contour of the real and imaginary parts is even, and positive and negative singularities are equal.

复振幅的实部和虚部零值线多为封闭的曲线，零值线交点的个数为偶数，并且正负相位奇异点的个数相等。

The one order differential model and convolutional model of impedance formula of amplitude versus offset inversion were established. Impedance inversion formula from AVO was derived based on Bayesian framework. Methods of using Huber function as prior model parameter distribution and covariance matrix from well log as constrains were developed. The P-wave impedance, S-wave impedance and density were calculated by the conjugate gradient algorithm.

为此建立了振幅随偏移距变化波阻抗反演公式的一阶差分模型及褶积模型，推导了基于贝叶斯理论的AVO波阻抗反演公式，给出了采用Huber分布作为模型参数的先验分布及测井数据的参数协方差矩阵作为约束条件的实现方法，并利用共轭梯度法计算了纵、横波阻抗及密度。

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 technique of stratal slices can reveal the isochronism of sediment disperal patterns with high-resolution. And the sedimentary systems can be analyzed with lithologic log data. A shelf-edge deltaic system including fluvial plain, deltaic plain, deltaic-front, prodelta, and incised valleys was identified in Olmos formation of Gold River North Oilfield.

相位转换后可以通过地震振幅分析岩相；地层切片技术能更精确地反映研究区等时的沉积分布特征，结合岩性测井资料可以较准确地分析沉积体系；Olmos组可以识别出一套河流－三角洲沉积体系，包括前三角洲亚相、三角洲前缘亚相、三角洲平原亚相、曲流河相和下切谷沉积等。

In conclusion this phase is actually important in the framework of KMT theory.

这个结果充分说明N-N振幅的相位对KMT类型的理论计算也起重要作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
