On the basics of chapter three, a new scheme of photon acceleration by which the large amplitude nonlinear density perturbation excited by a finite length driving beam in plasmas is used to upshift the frequency of an ultrashort laser pulse.

第四章在第三章研究基础上，提出一种新的光子加速机制，即，利用有限长电子束激励的大振幅非线性等离子体电子密度扰动来对入射的光脉冲进行加速。

It is shown that under certain condition the convection may also develop in a stable stratified atmosphere, because the ambient wind field and stratification variate with the development.

分析结果指出，对流除在不稳定和中性稳定层结条件下可以发展外，在稳定层结条件下也可以得到发展，并且扰动的振幅最后均趋于有限值。

It points out the relationship between energy vector diagram and amplitude vector diagram .

提出简谐振动"方根能量"矢量图的概念（以下简称"根能量"矢量），指出了根能量矢量图和振幅矢量图的关系。

Using particle image velocimetercombined with CFD dynamic mesh,an experimental and simulation study was carried out on flow field in the near-wall region outside a vibrating tube.The charts of velocity vector of flow field outside the tube under five conditions with amplitude 1.3 mm and frequency 5—25 Hz were obtained,and the cosine of average synergy angle of flow field outside the tube was calculated.

采用粒子图像测速与CFD动网格相结合的方法，对振动圆管外近壁区流场进行了实验及模拟研究，得到了振幅1.3 mm、频率5～25 Hz范围内的管外流场速度矢量图，计算了不同工况下管外流场的平均场协同角余弦值。

"In this process you're going to have up days, with five-plus percentage swings, and you're going to see down days, five-plus percentage swings," said Ryan Larson, head equity trader at Voyageur Asset Management in Chicago.

Ryan Larson，芝加哥Voyageur资产管理部交易经理称，在目前的市场状态下，你会看到市场的上涨下跌，振幅在5%左右。

For single vug,when the lateral scale of vug is smaller than Fresnel radius,and the vertical scale is smaller than tuning thickness,the reflection amplitude of vug is proportional to its scale. For carbonate reservoir with random arranged vug,seismic wave amplitude is proportional to vug density.Key words random medium;forward modeling;carbonate;vug

对于单个的溶洞而言，当溶洞横向尺度小于菲涅尔带半径，纵向尺度小于调谐厚度时，溶洞反射振幅与溶洞尺度成正比例关系；对于随机分布孔洞的碳酸盐岩储层而言，地震波能量与孔洞密度成正比例关系。

This paper presents a new method for water wave animation based on the theory of small amplitude wave and the technical model of c.

该文基于小振幅波理论和细胞自动机的模型，给出了一种实现水波动画的新算法。

Be in phase, and the amplitude of the wave pattern will be small.

通常，连续反射的波的位相不完全相同，因此合振幅很小。

The variation of wavelength, wave speed and amplitude of wave versus liquid pressure was obtained.

测得了不同压力下的扰动波波长、波速和振幅。

The fact that the speed of water wave s varies with wave length and with amplitude leads to a wide variety of effects.

实际上，水波速度的波长随着振幅改变，导致各种不同的效应。

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。
