In view of the limitations of the mathematical method used in the co.tainer terminal logistics system, this paper uses Unity3D to establish a co.puter simulation model for the co.tainer automated yard, which dynamically displays the operation process of the co.tainer automated yard logistics system in real time. Through the plane four-parameter co.rdinate co.version method and by taking the Shanghai urban co.struction co.rdinate system as the medium, it co.pletes the co.version from the satellite positioning reference ellipsoid co.rdinates to the three-dimensional virtual scene co.rdinates. The example results show that the method is reliable and practical, improves the accuracy and efficiency of positioning, and provides a reliable reference basis for the co.tainer terminal logistics system.

Rising co.plexities in co.struction projects management has boosted the importance of relationa co.tracting(RC) in the field. RC is based on reco.nition of mutual bene fits and win-win scenarios gained through more co.perative relationships between co.tracting parties There have been a range of RC initiatives across many co.ntries towards deeper co.laborative relationships; however, such formal RC approaches are not yet wel established in china. In this paper, the feasibility of implementing RC in the china's public co.struction projects is investigated. The results indicate that RC is highly feasible for implementation in china due to its theoretical bene fits, its alignment to Chinese culture, and its behaviors in past public co.struction projects. three strategies for facilitating the implementation of RC in china are proposed.

By co.bining sequencing batch reactor (SBR) activated sludge process and co.structed wetland (CW), this study is to achieve the domestic wastewater treatment. Our purpose was to determine the optimum operating parameters of the co.bined process. The process involved advantages and shortages of SBR and CW. Under normal temperature, the 3rd cycle (SBR’s operation cycle is 8 h: inflow for 1 h, limited aeration for 3 h, sediment for 1 h, outflow for 1 h, and idling for 2 h; CW’s hydraulic retention time (HRT) is 24.8 h and hydraulic loading is 24.5 m3/m2 d) was the best cyclic mode. The effluents can meet the standard GB/T18921-2002: "The reuse of urban recycling water: water quality standard for scenic environment use". In the 3rd cycle, the efficiency of CW was the maximum, and energy co.sumption of SBR was the minimum. Under the co.dition of low dissolved oxygen, the removing efficiency of chemical oxygen demand (co.) and ammonia was not affected obviously. Simultaneously, nitrification and denitrification phenomena occured and phosphorus was absorbed obviously.
