Methanobactin mediated the reduction of chlorauric acid by 1,4-resorcinol Figure 1.
The structure of methanobactin as well as growth and physiological data argues for its function as a copper-sequestration compound[8~10].

Process and technology Compared with developed countries, our process and technology in oil industry are backward, especially in energy conservation and emission reduction.
Compared datum of 2009 with datum of 2008, we get Table 1.

Besides, garment hangtags are comprised by double sided printed card, single page printed card style, double back as well as book style, which have been found preferable to hangtag design for multiple brand and types of garment, such as the double sided printed card for “A02”, book style for “B.TBoy” cowboy series as well as the double back for“DIADORA” Several redesigned hangtags have been found as per new garment series by garment brand during data analysis process so as to meet the style of new product for incremental sale such as “KITTY” series garment of Metersbonwe brand.
Reduction of intuitive judgment during design process.

Prefabricated concrete construction and used precast Hollow slabs of masonry buildings as two of the most important architectural systems, applied a penetration rate of more than 70%.But precast concrete technology in China is relatively backward, on the one hand because of the large number of precast concrete structural in Tangshan earthquake damage which lend to more conservative application of prefabricated structures.The other hand,the precast concrete elements exist span is small, low bearing capacity,ductility, and a single species, and many other issues, these are also a serious impediment to the development of precast concrete structures in China[3]. 3.Present situation of study on precast concrete frame structure system at home and abroad As the level of application of precast concrete in China is relatively backward, and lacks the associated experimental data and theoretical analysis.
Many researchers study the connection of the precast concrete structure at home and abroad.Such as: (1)In 1994, the United States national earthquake disaster reduction committee recommended a ductile connection, it can be used for precast concrete frame system, can also be used for precast concrete slab-column structure, ductile connection with excellent non-linear response characteristics, but its layout does not need to avoid the plastic hinge region and node coincide

Fig.6 Scratch test data of CrNx coatings with different interlayer Fig.4 Nanohardness, Elastic Modulus and H3/E2 values of CrNx coatings with different interlayer Fig.5 Typical load-displacement curves of CrNx coatings with different interlayer The measured nanohardness and elastic modulus of chromium nitride coatings are in the range of 23-31GPa and 259-283GPa, respectively.
Coupling with its surface morphology characterized by AFM, The reduction in root mean square roughness of CrNx coatings in sample 1 also indicates the mechanisms for stress relaxation.

Influence of Shield Tunneling on a Nearby Buried Pipeline Dayong Li 1, a, Lixue Cao 2,b and Dewei Fan 3,c 1Key Laboratory of Civil Engineering Disaster Prevention and Mitigation, Shandong University of Science and Technology, Qingdao, Shandong, 266510, China 2Key Laboratory of Civil Engineering Disaster Prevention and Mitigation, Shandong University of Science and Technology, Qingdao, Shandong, 266510, China 3Research Institute of Structural Engineering and Disaster Reduction, Department of Civil Engineering, Tongji University, Shanghai, 200092, China aldy@sdust.edu.cn, bhuanxue.1@163.com, cvanderveer@163.com Keywords: Shield Tunneling, Buried Pipeline, Winkler's Beam on elastic foundation, Displacement of buried pipeline, Stress of buried pipeline.
Substituting the above data, we get initial parameters: Substituting the above initial parameters into Eq. 25 to Eq. 28, we may get displacement, rotation, bending moment, shearing force at any position along the buried pipeline.

In case of buses, the selection of new technologies is somewhat restricted compared to passenger cars, due to the fact that heavier buses already use very efficient diesel engines, and that the potential for weight and air drag reduction is constrained by the payload carrying requirements.
As the original engine model may not be used in the system. therefore, mathematical models of controllable motor may be replaced for the engine model whose specific data can be determined by characteristics of the engine.
