Truss bridge and the arch bridge demand the introduction, there is how they prevent excessive bending of the bridge - has been answered ...

求桁架桥和拱形桥的介绍，还有它们是怎么防止桥面过分弯曲的-已回答。。。

Downstream, the next bridge is Westminster Bridge; upstream the next is Vauxhall Bridge.

在其下游相邻的桥是威斯敏斯特桥，上游相邻的桥是活克斯豪桥。

Until 1750, when Westminster Bridge was opened, London Bridge, first built in the 10th cent., was the only bridge to span the Thames.

是唯一的桥梁，横跨泰晤士河。

The theoretical study shows that the central frequency is linear with the square of the voltage applied on the Wheatstone bridge. The adjustable frequency range can be extended by decreasing the wide of the bridge and the resistance of the Wheatstone bridge.

理论研究表明：中心频率与电桥电压的平方成线性关系；中心频率的可调节范围可通过减小梁的宽度和压敏电桥的电阻来扩展。

A conclusion is given that the cable-stayed arch bridge is novel and artistic. It is more important that the arch axile force of the cable-stayed arch bridge may adjust, thus, the bridge may develop to the great span direction.

由此得到结论：斜拉拱组合桥不仅桥型新颖美观，更重要的是拱肋轴力可调，该拱桥桥型可以向大跨度方向发展。

There are three different dismountable bridges: Arched Bridge, Bascule Bridge and Pillar-Support Bridge.

这是三组可拆装的桥梁：拱桥、吊桥和柱桥。

A Bascule Bridge can span the longest distance because of its light weight. Arched Bridge: A curved arch is fixed at both banks to support the bridge.

吊桥能跨越最长的距离，因为它们重量轻；拱桥：一道弯曲的桥拱牢固地固定在两岸，支撑起桥梁。

First across a wood bridge, being the middle span of it, hear the sound of "Caca", and the bridge is broken with our car down. We are shocked after the var passes over, the bridge reform to the original style!

先是经过一座木桥，到了桥中央，只听桥咯砟一声响，桥断了，我们的车也向下一沉，咯噔一声，吓人一跳，车过以后，桥又恢复原状！

A new organic compound, trans-2--5-dimesitylborylthiophene (abbreviated as DMASBT, 5) with dimesitylboryl, dimethylamino and styryl-thiophene as electron acceptor, electron donor and conjugate bridge respectively, was synthesized. Its crystal structure determined by X-ray diffraction method indicates that the B-C bond between B atom and it bridge is obviously shorter than those of between B atom and mesityl groups. This remarkably strengthened B-C bonding can be regarded as an evidence of additional p-7t conjugation between the B atom and n bridge.

合成了以含硼基团为电子受体，以二甲胺基为电子给体，以苯乙烯基噻吩为共轭桥的新化合物2-[（4'-N，N-二甲胺基）苯乙烯基]-5-二米基硼-噻吩 trans-2-[(4'-N， N-dimethylamino) styryl]-5-dimesitylboryl-thiophene（简写为DMASBT，5）。X射线衍射方法测定其单晶结构表明，硼原子与π共轭桥之间的硼碳键相对于其它的硼碳键明显缩短，硼与π共轭桥之间存在除了σ键之外的p-π共轭作用。

In order to understand the dynamic property of extradosed cable-stayed, built up its plane continous rigid-frame model and compared with each other, concluded that the former is more complex due to the remarkable coupling effect of cable, pylons and box-girder. The dynamic property of box-girder decide the dynamic property of the bridge, whose whole structure is comparative rigid. This paper indicated that the bridge is not attribute to flexible structure, because its basic free vibration cycle is more shorter than the cable-stayed bridge.

为了更好的理解矮塔斜拉桥的动力特性，还建立了平面梁单元的连续刚构模型，并与平面梁单元的矮塔斜拉模型进行了对比分析，结果表明，矮塔斜拉模型由于索、塔、梁的高阶振型耦合显著，其振型较连续刚构复杂，灵江大桥的动力特性主要由主梁的动力特性决定，其结构整体刚度较大，基本自振周期较斜拉桥短，不属于柔性结构。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。

On one hand, there are discussions with the works council and union about extension of short time working up to the end of September.

一方面，有讨论，工程理事会和联盟关于延长工作时间短至9月底。
