Analysis of biological dirt on the sewage-source heat pump exchange surface Li Bai1,a Tan Liu1,b Yingzi Lin1,c (1Jilin Institute of Architecture and Civil Engineering, Department of Municipal and Engineering, Changchun, China) abaili0308@163.com,bltmapro@163.com,clinyingzi1000@163.com, Keyword: Heat exchange surface; Moisture content; Dirt component; Abstract: This experiment research the dirt adhere on heat exchanger in the sewage-source heat pump system，which contained moisture content test, ash content test, a digital microscope observation, scanning electron microscope observation, X-ray diffractometer analysis.
Because the actual engineering of tube heat exchanger are not easily do dirt sample preparation and intact observation, it is less that the research of the tube type heat exchanger’s dirt property study in China, but the actual engineering of heat exchanger is mainly tube type , therefore the research of tubular heat exchange surface’ dirt have more practical value[2].

Architectural design using AutoCad and Sketchup Yun Ma1 Shanhong Zhu2 1 School of civil engineering and architecture ,Xinxiang university, Henan, China 2 School of Computer and Information Engineering ,Xinxiang university, Henan, China Email: 14878670@qq.com zshazhu@163.com Keywords: Architectural design; AutoCad; Sketchup; application technology Abstract: Architectural design is a creative work, the final results of it is image and visually expressed in the form of drawings.
Introduction Architectural drawing is a required professional course for architectural engineering,The abstractness of the course has always been the difficulty in the teaching process, especially the descriptive geometry which needs to have a strong imagination space[1].SketchUp is popular in recent years the building design is generally a 3 d modeling software, three-dimensional model is established by means of it can quickly, and can get a visual on three sides by orthogonal projection characteristics( widely applied to the projection way in teaching),feedback to the teaching, the abstract to figurative, help students to understand and solve problems.With AutoCad software developing more than ten years in our country.AutoCad software also is continuing to improve its function.
Conclusion Through the above analysis, realize SketehUp on architectural cartography teaching has great advantages, after mastering the basic operation SketehUp at the same time, a comprehensive grasp of CAD drawing skills,with AutoCad software applying in the engineering design, a comprehensive grasping of CAD drawing skills is a concerned program in realize the standardization, standardized operation.It is a relevant procedures to achieve standardization, standardized operation.

Impact Analysis of Geogrid Node Size in Stretch Forming Zhenhua Yi School of Civil Engineering, Shandong University, Jinan 250061,China; Zhenhua_yi@163.com Keywords: Plastic geogrid; Node fracture; Stretch forming; Punching size; Numerical simulations Abstract.
It shows that the biggest engineering strain along the stretching direction decrease gradually with the increase of the radius.
Fig.10 Mises stress and maximum engineering strain along the tensile direction with different radius As shown in Fig.11, compared deformation contours on the symmetry plane along plate thickness direction. it shows that the contours of rib part is basic coincidence when mesh stretching with different radius get to the same draw ratio.

The dynamic testing method for damage diagnosis of multi-story masonry buildings Fengge Li 1, a, Hong Yu 2, b 1 Architecture and Civil Engineering School, Inner Mongolia University of Science and Technology, Baotou, 014010, P.R.China 2 No.5 middle school of Baotou steel & iron, Baotou, 014010, P.R.China alfg0626@sohu.com, byuhong450@sohu.com Keywords: damage diagnosis; dynamic detection; artificial neural network Abstract.
In this case, dynamic testing method is paid attention to by the engineering.
Using this method, it is easy to measure structural dynamic response in engineering structure, and high detection efficiency can be achieved and the test isn’t influenced by decoration materials cover, and this method has broad application prospects.
The former engineering experience according to literature [1], the structure frequency of the field measurement is less affected by noise, having high precision measurement, while each mode of vibration is influenced by noise, having low precision measurement.

In the subway engineering, the stray current caused by leaking in the rails with high strength.
It will be likely to activate the bound chloride ions of internal concrete and lead to the release of bound chloride into free one, thus forming a potential threat of concrete durability in subway engineering.
Thereby, concrete in subway engineering is often under a coexisting condition of stray current corrosion and chloride-induced corrosion.
Consequently, this paper mainly studies the effects of the strength and action time of stray current on chloride binding and give more suggestions for improving the service life of concrete in subway engineering.
