First, the absorption peak of 1 465 cm 1 was selected as the characteristic peak for determining their kinematic viscosities. And then correlation of the kinematic viscosity and the absorbance at characteristic peaks of corresponding infrared spectrum of standard oil and used oil samples was analyzed, re- spectively, and two regression equations were proposed. Finally, the regression equation of standard oil was corrected through other 20 new oil samples. The results show that determining kinematic viscosity of new lubricating oil 50-1-4Ф and the used one by FTIR is feasible and reliable.展开更多

It leads to a reasonable solution to space expansion by reclamation. Construction of new deepwater terminal is the best usage of land resources and can strengthen the status of Shanghai as an international shipping center,thus support the preparation and strategic decision of future urban development of Shanghai.展开更多

文摘From a strategic perspective,the paper presents a forward-looking thinking supported by interdisciplinary of modern logistics,estuary and coast,environment and ecology,economic management and mathematical statistics. It leads to a reasonable solution to space expansion by reclamation. Construction of new deepwater terminal is the best usage of land resources and can strengthen the status of Shanghai as an international shipping center,thus support the preparation and strategic decision of future urban development of Shanghai.
