The stress distribution of section in wide and thin box girder subjected to simultaneous bending and axial forces doesn't conform to the assumption of the plane section, and the transverse stress distribution is uneven; with the increasing of bridges' span and the lowering of security repertory, to consider the uneven of stress distribution in calculation of design and construction control, and to analyses the shear lag effect in the process of bridges' construction and using are bound to have important engineering value and theorical significances.

在压弯荷载共同作用下，宽而薄箱梁的截面应力分布并不符合平截面假定，沿横向分布不均匀；随桥梁跨度的加大和安全储备的降低，在设计计算和施工控制计算中考虑这种不均匀性，准确分析其在施工和使用阶段的剪力滞问题具有重要的工程价值和理论意义。

Prevision of education is very significant for engineering system of high education to adapt to the fast development of the advanced manufacture technology and mode,to satisfy the needs of high making persons for manufacturing modernization.

The electrically operated Swing Bridge (1865--1876), one of the greatest engineering achievements of its time, is on the site of Roman and medieval bridges.

电气操作的悬挂桥(1865～1876年)是那个时代最伟大的机械工程之一，它坐落在罗马时期和中世纪时期桥梁的遗址上。

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。
