A trial experiment is done on the damage region detection of latticed shell structures based on the difference of high-order modes.

提出了一种基于高阶模态振型差的网壳结构损伤区域检测设想，并进行了试验探索。

In this paper,a recursive least squares algorithm for frequency domain identification of non-integer order systems is presented.

本文提出了一种非整数阶系统频域辨识的最小二乘递推算法。

In this paper, the propagation and focus properties for several modes describing hollow beam are analyzed, and the focus properties for hollow gaussian mode are particularly discussed. Furthermore, a new mode, high-order Bessel-Gauss mode, is put forward to describe hollow beams. The results for high order Bessel-Gauss beams propagating through lens focusing system and free space are derived by terms of Collins integral formula.

本文分析了几种描述空心光束数学模型的传输特性和聚焦特性，着重讨论了描述非中空光束的数学模型的聚焦特性；同时提出了一种描述完全中空的空心光束的新模型――高阶贝赛耳高斯模型，并且运用Collins积分公式，分析了这种新模型的空心光束的传输特性和聚焦特性。

Lignite also has an analogical structure similar to lignin, it has wide usages in the fields of industry, agriculture, medicine and so on.

褐煤是植物残体经过漫长的地球物理化学过程转变而来的一种低阶煤，具有与木素相似的结构。

A new modified limiter is presented, which increases the stable convergence rate.

研究提出了一种高阶精度TVD格式的限制器，具有稳定快速的收敛特性。

The chapter two, by using reduction to absurdity and estimating the differential inequality, we investigate the oscillation of a kind of even order half- linear differential equation, and we give an example to validate the theorem.

在第二章中，我们利用反证法及对微分不等式的估计研究了一种偶数阶半线性微分方程解的振动性，接着举了例子验证所得定理。

high - grade gentle type ; lack one type ; positive power function ; successive integral ; linear differential equation ; solution

定理1： '卜'阶线性微分方程〔呻〕+ f的通解为：，二命{卜二〔丁〔·'一叮。·，dxldx…〕dx证明：两边同乘积分因子。，得： e

The general constitutive equation of the rheological component model is a linear ordinary differential equation of N order, which is a typical SISO linear stationary system.

岩石流变组合模型的本构方程通式—n阶线性常微分方程，是一种典型的SISO线性定常系统。

Now we have used the big dictionary for seat works, it is named Longman Dictionary of Contemporary English.

现在我们在做练习册时，使用一本大字典，叫做《当代朗文高阶英汉词典》。

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。
