扰动

Fast locking time, low jitter performance and low power consumption are required in nearly all PLL applications in modem IC systems. Thus the design of PLL must generally deal with a tight tradeoff between the locking time and the amplitude of the ripple on the control line of oscillator.

It combines algorithmic derivations, perturbation theory, and rounding error analysis, all enlivened by historical perspective and informative quotations.

它结合算法的语源，扰动理论和舍入误差分析，被历史远景和信息丰富的摘引使活泼的全部。

Using the properties of base solution vectors of the linear restriction equations, a condition to maintain the same discriminant result between the sampled observations of changed and unchanged was obtained: the disturbed row vector of sampled observations was satisfied all linear equations whose coefficients were the base solution vectors of linear restriction equations.

利用约束条件方程组基础解向量的性质得出了使数据变化前后的判别分类结果保持不变的条件：数据扰动行向量必须满足所有以约束条件方程组的基础解向量为系数的线性方程组。

Analyzed by our numerical method, Sakharov small disturbance experiment can give a credible viscosity coefficient.

利用本文数值解建立起来的实验数据分析方法，Sakharov小扰动方法可以给出更为可信的粘性系数测量结果。

Disturbances with various patterns were exerted to the open channel flow in a flume to quantitatively investigate the variation of turbulence structure during sand ripple formation and its influence on sand movement and river bed evolution. The variation process of flow velocity is measured by means of ADV with sampling frequency of 50Hz.

本文通过在水槽实验中采集的流速过程数据，定量地研究了沙纹阶段明渠水流在不同形式扰动作用下的湍流结构，以及湍流结构对泥沙运动和床面演化的影响。

Finally, in Chapter 5, the mechanics of sandpile avalanche has been studied using a horizontal vibration as an outside perturbation.

第五章中，通过可调的水平振动作为扰动，我们研究了沙堆受外力崩塌时的物理机理。

They are the effect of boundary restriction on the granular flow, the bulk elasticity of granular assemble and the effect of horizontal vibration on the sandpile avalanche.

本论文通过实验和计算机模拟的方法研究了颗粒物质流动和静态的几个问题，主要包括三个方面：外界约束对颗粒流状态的影响，颗粒系统整体的弹性和水平扰动对崩塌的作用。

Supracrustal sequences free of early strong deformation The early deformation of Jingangku formation complex of Hengshan Wutai group complex has formed a bedding parallel S〓 gneissic and schistosity, occasionally bedding parallel recumbent folds in layers. The early deformation of the near-horizontal ductile shearing isn't very strong in Wutai group complex. The orientation of shear movement is NNW—SSE.

经受早期强烈变形的表壳岩系岩系恒山五台岩群金岗库岩组和五台山五台岩群最早期的变形是平行地层层理的S1片麻理和片理，偶见层内的顺层掩卧褶皱，这些早期近水平韧性剪切变形在五台岩群大都不甚强烈，对地层层序的扰动也很弱，剪切运动方向是北西西——南南东向的。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
