桥塔

The dynamic properties of the tower of Runyang Yangtze River Nancha Suspension Bridge were studied before and after installing coble by finite element method and the modal experiment analysis based on environmental stimulation.

通过有限元分析和基于环境激励的模态试验分析，研究了润扬长江公路大桥南汉悬索桥挂缆前后桥塔的动态特性。

Captain Roland of the 99th Division recalled the sign on one of the west bank towers:"Cross the Rhine with dry feet, courtesy of the 9th Armored Division."

第99师罗兰德上尉回忆，西岸一座桥塔上挂着告示标语："过河不湿脚，装甲9师不得了。"

The varying temperature stress in the prestressed concrete pylon caused by sunshine is analyzed in this paper.

分析了预应力混凝土桥塔塔壁在日照作用下随时间变化的温度应力。

The temperature stress in the cross section of the pylon in sunshine is educed by the finite element method.

利用有限元方法，分析了桥塔断面在日照温度作用下的温度应力。

Fault condition includes the descent of cable force, sinkage of bridge tower and structure change of the main girder. Data recorded are cable force, girder stress, girder linetype, frequency response function, mode shape and etc.

其中损伤的形式有索力下降、主梁局部刚度变化以及桥塔不均匀沉降等，监测的参数主要有拉索索力、桥面线型、主梁应变等静态参数以及主梁固有频率、频响函数和振型等动态参数。

A combination of the wave superposition method and the modified spectral representation method is applied to a wind field simulation for whole bridge including the deck and the towers.

将谐波合成法与修正的谱描述法结合用于大跨度桥梁主梁及桥塔上的随机风场模拟。

This allowed the 1st Battalion, 86th Infantry Regiment, to cross the Meuse and secure a bridgehead.

这使得第一营和第八十六步兵团得以渡过默兹河并取得了一个桥塔。

When the Allies did mount an air attack against the Meuse bridgehead, German flak defences shot down over 40 percent of the French and British aircraft.

当盟军对默兹河边的桥塔发动空袭时，德军的高射炮防御击落了法军和英军超过40%的飞机。

The basic frequences of the two types of bridges are heightened by increasing vertical curve curvature of stiffening girder, setting vertical supporting members and stiffing connection.

增大加劲梁竖曲线曲率，桥塔处设置竖向支撑和缆梁跨中固结均能提高悬索桥的自振基频。

In traditional systems, anchorages within the pylon required large tension ties to resist the high splitting forces that would be generated.

在传统的系统中，桥塔内的支座要求连接有很大的拉力以抵抗可能产生的突发的力。

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。
