扰动

As we know, perturbed and optimization and varia-tional principle play an important role in nonlinear analysis.

It is defined as the difference between the expectation of the perturbed statistic and its true value.

它定义为受扰动统计量的期望值与实际值之差。

This design was developed to minimize disturbance of the soil core and use petrolatum to prevent edge flow.

Martin Luther stands as the originator of the doctrine of justification by faith alone, for he hoped that in this way he might be able to calm his own conscience, which was in a state of great perturbation, and consequently he took refuge behind the assertion that the necessity of good works over and above mere faith was altogether a pharisaical supposition.

马丁路德立场为发端的中庸之道，因信称义，单人，因为他希望他这样做或许能够平息自己的良心，这是在一个国家的大扰动，因此他躲避后面的断言必要性好的作品超越单纯的信念是全然是pharisaical假设。

Simulation results show that using the improved phase diagram several types of SDPQD can be detected and classified easily and effectively.

仿真分析表明，利用改进后的相位图可以简单有效地实现对常见的短时扰动的检测与分类。

The algorithm avoids the calculation of integral phase constant by exploiting the differential Doppler frequency data, thus its capability of detecting weaker ionospheric irregularities has been enhanced.

在数据采集过程中引入了GPS标准时间；重建算法的特点是利用差分多普勒频率数据避免了相位积分常数的计算，提高了对较弱的电离层扰动和不规则结构的检测能力。

In PAUT, variations existing in the testing material and those in the system lead to phase and amplitude aberrations in ultrasound signal.

在相控阵列超声检测中，检测材料以及检测系统等方面存在的扰动因素引起了超声检测信号的。。。

A parameter design means of power system stabilizer is proposed in this paper, which uses both smalldisturbance method and time-domain digital simulation based on analysis of phase compensation of voltage vector.

在电力系统稳定器参数的设计、优化中，研究采用了一种基于相位补偿原理，结合小扰动分析与时域数字仿真的PSS参数设计方法，以及频率响应测量与相位观测相结合的现场试验方法。

Therefore the disturbance of the phase velocity or meander amplitude could make the motion of the fluid particles chaotic.

Constant study indicates that atmosphere turbulence is one of the primary factors that affect the precision of measurement in photoelectricity large-scale measurement instrument.

经过长期的研究，发现大气扰动是影响大尺寸光电测量精度的主要因素之一。

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。
