Construction Engineering 建筑施工
All civil engineering projects have four distinct phases: planning, designing, construction and operation. The construction phase turns the project design into reality and the civil engineering contractor is responsible for the construction work. His overall objective is to complete the construction work efficiently within an estimated time to maximize his profits on the contract.
现场准备 包括移走和清理拟建场地地表上所有的建筑和生长物。对于小型建筑和树木采用推土机即
可，大型建筑必须拆除。
Unit 2 Construction Engineering
Earthmoving This includes excavation and the placement of earth fill. Excavation follows preparation of the site, and is performed when the existing grade must be brought down to a new elevation. Excavation generally starts with the separate stripping of the organic topsoil, which is later reused for landscaping around the new structure. Excavation may be done by any several excavaters, such as shovels, draglines, clamshells, cranes, scrapers .

《新编汽车专业英语(第3版)》Unit 2-Passage A
• Its reciprocating movements in the cylinder transform the energy of the expanding gases into mechanical energy．
• Crankshaft and flywheel group includes the • following components (see Fig. 2-5):
• Crankshaftis one of the most important parts in the engine．
• It is held in the crankcase in the cylinder block and converts the reciprocating motion of the pistons into a rotary motion for the drive wheels．
Unit Two Engine Construction
Passage A Crank Mechanism and Its Main
Components
• Crank mechanism is one of the major motion mechanisms of the engine．
• Its function is to transform the reciprocating movement of pistons into rotary movement of the crankshaft, offering torque to make the drive wheels turn (see Fig.2-1).
