无变形线

The use of the free undamped normal modes is seen to ensure that the linear and angular momenta of the distortional motion vanish.

看来采用自由无阻尼正规模态可保证变形运动的线动量和角动量为零。

Collarband, no occupiers whether round, square, acuminate or in ironing all keep it open deformation, had better be fixed shape and ironing, If there is a lead of iron wire, don't general plait, just after death, while it is still hot, with warm hands, gently press fold look like this will lead to live.

领口部位，无领者不论是圆形，尖形或方形，在整烫时都注意不要把它拉开变形，最好是固定形状再加以熨烫；如果是有领片的，不要将领褶线烫死，只要再烫以後，趁它还是温热的，用手翻折轻压，这样子领片看起来会比较活。

Considering minimization of total wire length as the objective, it allows virtual blocks to transform into rectilinear shapes without overlaps and selects the optimum shapes for virtual blocks. It is based on the dead space block assignment and pin allocation during the process of packing.

该算法以线长最小化为目标，通过在位置优化过程中对虚拟模块进行无重叠的直角多边形变形来实现虚拟模块的形状优化，形状优化过程是基于模块填装过程中的空白区分配算法和引脚分配算法，并以降低线网在半周长模式下的线长下限为其主要理论依据。

Based on new WuhanGuangzhou railway passenger dedicated line engineering practice,this paper introuduces the key technologies for the deformation monitoring, data management and analysis system, the prediction method and assessment criterion are put forward to determine the reasonable time of unballasted track laying to guarantee the quality of unballasted track.

以武广铁路客运专线为基础，系统地介绍了线下结构物沉降变形观测关键技术，数据管理与分析预测系统，提出了工后沉降的预测方法及评估条件与标准，合理确定无碴轨道开始铺设时间，以保证客运专线无碴轨道结构铺设的质量。

The use of the free undamped normal modes is seen to ensure that the linear and angular momenta of the dis to rtional motion vanish.

看来采用自由无阻尼正规模态可保证变形运动的线动量和角动量为零。

The results of filtrating LPS under low pressure showed that metamorphosing property between LPC and polymer coils in a normal polymer solution was different.

LPS形成后改变体系盐浓度，LPC的尺寸即发生变化，说明LPC比较松散，具有良好的变形性，LPS中分散的LPC与聚合物溶液中聚合物线团的水化性能无本质差别，不是凝胶微球。

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。
