摘要:
The contradiction among population, resource and environment has become increasingly evident that requires the manufacturing industry to improve the compatibility of its activities and the environment. Green supply chain management is a valid way to resolve the conflict between manufacturing industry and the environment based on a systems point of view and the concept of integration. In the content of this paper, the concept of green supply chain would be combined with the method of DEA and it is established from the perspective of input and output in order to offer academic reference and practical guidance to automobile manufacturing industry for moving toward green development that is a set of complete carbon performance evaluation system of automobile manufacturing industry in green supply chain.

摘要:
Single nanowire becomes attractive as a basic component of various nanodevices. Nanowire joining is one of the crucial operations in micro-nano manufacturing. Compared with other joining methods, such as electrical current heating and mechanical pressure, laser illumination can yield metallic contacts through local precision nanosoldering. In this paper, the authors report the joining of one single copper nanowire (CuNW) to a silver film by a laser illumination method. They first cut the silver film on a flexible substrate to form a gap of about 1–4 μm by a 1030 nm femtosecond (fs) pulsed laser. Then, they coat CuNWs by dripping nanowire solution onto the gap, bridge the gap, and then join single CuNW with the fs pulsed laser. By comparison with scanning electron microscope images after and before laser illumination, it is found that the local silver film melts, then wraps partial CuNW, and finally crystallizes. So, the joining is through a part of CuNW embedded in a silver film. In addition, the authors further analyze the joining situation by directly measuring the resistance variation between after joining (Ra) and before joining (Rb). It is demonstrated that the resistance ratio of Ra to Rb decreases from 0.835 to 0.172 with increasing laser power from 10 to 40 mW for 3 s of the laser illumination time. The resistance ratio of Ra to Rb decreases from 0.936 to 0.368 with an increment of the laser illumination time from 1 to 4 s at a laser power of 30 mW. Finally, the authors find that the welded single CuNW enables sensing of glucose at a concentration of 10−5M.

BIM Technology;Construction Project;Cost Control
摘要:
The cost management of traditional construction projects has the following shortcomings. The calculation accuracy of engineering quantity in bidding quotation is not high; the drawing is not easy to identify; call of historical data is inconvenient; dynamic management and refined management are lacking. This article discusses the connotation of BIM technology specifically and the application of BIM technology in cost control management of construction project. BIM technology can improve the quality and efficiency of cost management, and has become one of the main trends in the development of construction. BIM technology has significant advantages. Applying it in cost management can help reduce engineering costs to a large extent, promote the progress of the project, and gain good practical results.

摘要:
After analysis for the defects and limitations of the existing calculation have been put forward. Regarding the unawareness about a percentage of brick dregs in the recycled aggregate, it designed a test about the water absorption of recycled aggregate with brick dregs and studied the features of water absorption of recycled aggregate with different proportions' brick dregs. Based on the existing calculation methods, it put forward a calculation method of the additional water in the mixing proportion design about the recycled aggregate with brick dregs allocating recycled concrete. It has certain value of application and promotion.
