扰动

The famous Kolmogorov-Arnold-Moster theory studies the perturbations of integrable systems, anti-integrable limit theory proposed several years ago studies the perturbations of"totally"chaotic system.

著名的KAM（Kolmogorov-Arnold-Moser）理论就是研究了可积系统的扰动。

The thixotropy of wetland soil is studied at three depths of soil, which can obtain the coupling effect of depth and stewing time on recovery of soil shear strength.

对湿地软土的触变性进行了3个不同深度处的试验研究，得到了深度和静置时间对扰动后土体抗剪强度恢复的耦合影响。

Secondly, we discuss the features of prediction models GM (1, 1) and SCGM (1, 1), and indicate that both are modeling methods for energy system, in which GM (1, 1) model requires a tiny develop coefficient while SCGM (1, 1) model not, while both are sensitive to disturbances and mutations.

讨论了GM（1，1）预测模型和SCGM（1，1）预测模型的特点，指出两者都是对能量系统建模的方法，其中GM（1，1）模型要求发展系数较小，而SCGM（1，1）模型则无此要求，两者对于扰动和突变都相当敏感。

After studying this phenomenon, the author finds that, the covariance matrix of the complex expressions of horizontal gradients of the disturbing gravity field elements has a structure of blockwise repetitive Toeplitz matrix, though the covariance within the disturbing gravity field elements is still anisotropic. Therefore, the collocation problem of the complex combination of horizontal components is similar to that of gravity anomaly, which makes the degradation be able to be completed by FFT transformation matrix.

作者研究发现，利用水平梯度的复组合，即复数表示后，扰动重力场元复组合之间的协方差函数尽管还是各向异性，但它们对应的协方差矩阵却具有分块 Toeplitz 循环阵的结构，因而水平分量复组合的配置问题与重力异常的配置问题相似，可以利用傅立叶变换矩阵进行降阶处理。

减小背景梯度是实现暂态电能质量扰动检测的关键。

The main work is as follows:(1)A professional program MANDISP2007 is developed to study the shaft torsional oscillation and fatigue loss problem.

本文将主要研究电力系统大扰动对汽轮发电机组轴系扭振的影响，主要包括：(1)开发研究机网扭振相互作用的专业软件MANDISP2007版程序。

In this paper we have shown that if the partial derivative of function f with respect to x is uniformly continuous then total stability of zero solution of system implies uniformly exponential asymptotic stability of zero solution.

本文证明了若系统有一致连续的偏导数，则系统的零解在经常扰动下稳定可推出零解一致指数型渐近稳定。

Under both disturbance conditions, the variation of total phosphorus was the same as PP.

扰动作用下，TP的变化规律与PP一致。

In order to improve power quality, the first problem to be settled is to monitor and analyze on transient voltage fluctuation.

为了分析电能质量问题，并为采取合理措施提高电能质量提供依据，对电能质量扰动进行监测与分析是首先要解决的问题。

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。
