Microscopic analysis of this from the perspective of three structural steel not typical for internal initiation mechanism

从微观角度分析本文三种结构钢没有出现典型内部萌生机制的原因。

An important part of this is making sure that structural steel is not only an ideal solution for building purposes, but an environmentally responsible solution as well.

一个重要组成部分，这是保证结构钢不仅是一种理想的解决办法，为建设目的，但对环境负责的解决方案等。

The structural system of steel grid bearing wall is a special structural system of residential building.

摘要钢格栅墙承重体系是一种较为特殊的住宅结构体系。

According to the general principle of material mechanics and section form of heavy steel structure,derives the calculation formula of polar moment of inertia J_ρ of heavy steel structure on torsion.

根据材料力学的基本原理，针对重型结构钢截面的形式，推导出其扭转时极惯性矩Jρ的计算公式

This paper discussed the lowering as a whole technology of Sutong Bridge 5 800 t weigh steel cofferdam from 6 respects such as selection of lowering scheme, design, fabrication, lowering techniques, synchronousness controlling and orientation.

从沉放方案选择、结构方案设计、制作和安装、整体沉放工艺、同步性控制及定位等方面阐述了苏通大桥主塔基础5 800 t钢吊箱的整体沉放技术与工艺。

This paper adopts the method of the combination of theoretics and experiment. It guides the experiment by academic analysis. On the contrary, results of the experiment can verify the correctness of the theoretics. It has provided the foundation for the conformation design of the connection area between arch rib in the side and rigid tie bar of the Xinguang bridge and its conclusions can also provide references for the design of other same type bridges.

本文采取理论分析与试验研究相结合的方法，通过理论分析指导试验研究，反过来用试验研究验证理论分析，为新光大桥边跨钢拱肋与刚性系杆连接区域构造设计的完善提供了依据，其结论也可供其它同类型桥梁结构的设计研究提供借鉴。

And it is meant to be a department responsibility there, in the same way as the responsibility for the design of the steel topside is the responsibility of the structural department

并且被认为是部门责任那里，以与对钢顶边的设计的责任是结构部门的责任

Its main structure is a triangular steel frame.

它的主体结构是一个三角形的钢屋架。

Friction and wear behaviors of Ti6Al4V alloys against GCr15 steel under dry sliding were investigated on high-speed pin-on-disc tribometer. Contact temperatures due to friction heat were measured by a thermocouple inserted into the hole of the Ti6Al4V pins. Morphology, composition and phase structure of the surface and subsurface for Ti6Al4V were examined by means of scanning electron microscopy, X-ray diffraction and transmission electron microscopy.

在高速销－盘式摩擦磨损试验机上考察了Ti6Al4V销与GCr15钢盘摩擦副的干滑动摩擦磨损行为，并在线测量了销试样的摩擦接触温度，利用扫描电子显微镜、X射线衍射仪及透射电子显微镜分别对Ti6Al4V摩擦表面和次表层的微观形貌、组织成分、相结构进行研究。

Integral joint is a new-type structure that has been already adopted in the long span steel truss bridge in the last few years.

整体节点是近年来在大跨度钢桁桥中采用的一种新型结构型式。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
