分析结果表明，随着桥面板厚度的增加，板梁挠度及板梁底横向拉应力逐渐减小，铰缝内的横向拉应力和竖向剪应力逐渐减小；随着铰缝深度的加大，各板梁挠度差逐渐减小，板梁底横向拉应力逐渐增大，铰缝内的横向拉应力和竖向剪应力逐渐减小；并且随着桥面板厚度的增加，铰缝深度对板梁桥的刚度及受力性能的影响效果逐渐降低。

Given two bridge-builders, a man and a woman, given a certain bridge to be built, and given as always the unchangeable laws of mechanics in accordance with which this special bridge and all other bridges must be built, it is simply inconceivable that the preliminary instruction given to the two bridge-builders should differ in quantity, quality, or method of presentation because while the bridge is building one will wear knickerbockers and the other a rainy-day skirt.

假定分别有男女两位桥梁建造者，要去建造指定的一座桥，在建造这一独特的桥及其它一般的桥的力学规律总是不变的情况下，简直不可想象，男女建造者所受的基本教育应有所不同；更不可想象，只是因为在施工时，一个穿灯笼裤，另一个穿防雨裙，而必须让他们在质量、数量及教学方法上接受不同的教育。

在晴川桥的瞬态动力分析中，模拟分析了当移动荷载以不同速度通过桥面时的时间历程动力响应以及在冲击荷载作用下桥跨结构的时间历程动力响应，并对桥跨结构在移动荷载和冲击荷载作用下的动力放大系数作了较为详细的分析。

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。

We proposed that π-interrupted spiro framework is an effective tool to tune the intermolecular interaction of chromophore moieties, which has been confirmed by single crystal X-ray diffraction analyses.

另外，我们设想螺桥是调制光电功能基团超分子作用的有效工具，设计了一个含螺桥的氧化噻吩寡聚物，这是一个有效的讨论螺桥是如何通过自身的参与来有效地调制光电功能基团的相互作用的模型。

For example, in the past, when Gul Zar's customers couldn't find the proper goods in Keqiao, he had to help them to search in Suzhou, Guangzhou and so on. However, now it has completely become a small potato in Keqiao. Whatever demands of the purchasers' can be met in Keqiao, this authentic China Textile City.

他认为柯桥的经商环境正变的越来越好，以前客户需要的有些产品柯桥附近的企业生产不了，所以他必须带着客户到苏州、到广州去寻找，但是现在无论客户有什么样的特殊需求，柯桥都能找到生产厂家。

Procecding from the view of system theory and making the actual require-ments as a condition in piling work ,the velocity parameter of unloaders was caculated by the use of ideal point method in comprehensive evaluation.At the same time .the total power was minmum and the productivity was maximum.

本文从系统理论的观点出发，以装卸桥在贮木场从事归楞作业的实际要求为约束条件，同时以装卸桥系统总功率大小和生产率最大为目标，采用综合评比法中的理想点法对装卸桥的速度参数进行优化计算。

Superstructure design, first determine the type of bridge, structural design, the choice of beam layout and positioning, the bridge is used in assembly-prestressed concrete simple hollow plate girder bridge, followed has been set in accordance with the structural design and calculation with Tendons.
