Abstract.A high precision reverse engineering design method for complex structural component which based on the meta feature is presented.
Introduction The design of complex structural component covers multi-disciplinary field and largely adopts reverse engineering at present.
As the measurement for impeller’s exterior shape and inner channel can’t be conducted in the same coordinate, 3-datum point location method is usually adopted in engineering for the alignment of multi-view point cloud data [4].However, the point features of silicone mould are difficult to extract as it is a soft material.
Although the average error has increased slightly, the increment is within 0.005mm, satisfying actual requirements in engineering.

Carbon Footprint Research of Landscape Engineering Based on Life Cycle Analysis—Take the Unoccupied Space Landscape Engineering of Wuhan Optics Valley Road(Optics Valley Road one—Liufang Road Section) for Example Tang Feiyun (Hunan Urban Construetion College ,Xiangtan, 411103 ,China) Key words: Carbon footprint Life cycle analysis Carbon emission Landscape engineering Carbon sink Abstract: Carbon footprint calculation has important guiding significance to carbon emission reduction, especially the carbon footprint research of landscape engineering based on life cycle analysis fully reflects the whole condition of carbon emission in the construction process and effectively guide the whole process conducted with low-carbon.
This essay attempts to preliminarily investigate the carbon footprint of life cycle analysis in the landscape engineering by combining with landscape engineering case and provide reference for following landscape engineering to reduce carbon footprint.
It is mainly appeared in stages of construction, maintenance management, operation and demolition with consuming actual materials, fossil energy and machinery machine-team. 3.2 Definition of calculation boundary of life cycle carbon footprint for landscape engineering This essay discusses the definition based on planning and design, construction, maintenance management and refurbishment and demolition of landscape engineering.
Since lack of plenty of quantitative research indexes, the carbon footprint is estimated according to normal processes of landscape engineering construction and management and with the help of empirical value, which are the key and difficult points to this research.

Study on the Cooperative Learning in the Teaching of Civil Engineering ZHANG Jintuan Hezhou University of the Guangxi Zhuang Autonomous Region, china 349853900@qq.com Key words: The teaching reform.
Civil engineering courses.
The biggest feature of cilvil engineering is the strong practicalness.
To construct a building we have to learn lots of knowledge, such as geotechnical investigation, engineering geological mapping, soil mechanics, engineering mechanics, engineering design, building materials, construction equipment, engineering machinery, engineering economy, etl.
Therefore, to carry out Autonomous and cooperative learning mode in civil engineering courses is in line with the professional training of civil engineering.

At the same time, proceed strict management and distribution of project funds, all materials purchased all open tendering procedures, put an end to all violations, actively cooperate with the audit department and finance department tracking audit drinking water safety project, project budget, step by step award of bid, completed award of bid, all must be strictly and prevent deformity engineering appearance, will let the limited funds to do more for the people. 2.4 Adjust measures to local conditions, scientific planning, careful construction, strictly the “four key” For each project must be through scientific analysis and demonstration, multiple scheme comparison according to the local natural conditions, the economic and social development, eventually determine the type and scale of drinking water and water supply engineering reasonable.
To strengthen the construction of quality management, we should conscientiously do a good job of each key link, mainly to do good “four key”.
Namely: material and equipment quality, construction, engineering quality and engineering completion acceptance.
The main engineering materials will been unified by the procurement of government; the establishment of quality supervision system of drinking water project tendering system and project, open tendering to drilling engineering construction team; in strict accordance with the drawings, design documents, engineering card and the related standard construction, the key parts of the important hidden engineering or engineering are timely check and acceptance, and at any time should accept supervision by the masses, and to be passed acceptance inspection, it can enter the next procedure.
The latter must be used for classes, there are plans to implement, make the limited funds to play as much as possible engineering benefit.

Furthermore, the analysis of fracture mechanism shows that, to the same material, the fracture mechanism is different under different stress states, and the key factor influencing fracture is also different.
The key factors influencing shear fracture angle Influence of stress state on shear fracture angle.
In the uniaxial compression test of brittle materials, frictional force between end face of test piece and pressure head of testing machine, and additional tensile stress produced in the materials when harder crystalline grain wedge in softer medium have changed original stress state at the fracture point, influenced the direction of fracture surface, and even fracture forms and mechanisms of materials.
