It was completed at the end of 1985. A 300 msw trimixed saturation diving experiment was successfully conducted in the complex by Chinese Underwater Technology Institute(CUTI) from May 22 to June 12 of 1987. During the experiment, 4 divers habitated in the complex for 20 days, and they performed 16 person-time excursion dives and 8 other tests. The result of the experiment indicates that the complex is well designed, suitably configurated, wholly integrated and steadily run, as well as of low leakage. The main functions of the complex have approached to those of the same kind in the world. The complex can be used as a basic facility for serving the nation's saturation diving technology, underwater operation, personnel training, etc.展开更多

However, along with the dramatically economic growth, there constantly emerges environmental and social constraints which may be great challenges of China＇s future sustainable development. In order to optimize the developmental mode, the latest national plan, ＂The 12th National Economic and Social Development Plan （2011-2015）＂, is establishing the ＂Main Function Zoning Strategy＂, which could be considered as a new prototype of national spatial plan and may cover all Chinese territories. Based on the latest ＂Main Function Zoning Strategy＂ stipulated in ＂The 12th National Economic and Social Development Plan （2011-2015）＂, the article builds main interlinks between the spatial development strategy and urban regulatory planning. Secondly, regulation factors in Chinese regulatory planning, which may implement the task of main function zoning, have been clarified and categorized. For each regulation factor, its regulation capability is defined by applying a coding method developed by the author. Finally, according to the output of the study, the spatial regulation approaches to implementing the ＂Main Function Zoning Strategy＂ in Chinese regulatory planning are analyzed.展开更多

A restricted development zone is a type of main functional area which provides agricultural products and ecological products, assures the supply of national agricultural products and the stability of ecosystems, as well as safeguards the ecological functions and agricultural functions of wider regions by restricting its own development. Therefore scientific, complete and operable industrial policy support is needed. Restricted development zones are distributed widely in western China. With the restriction of their main functions, differential industrial policies should be implemented in the development of the restricted development zones: Dealing well with the relationship between industrial development and ecological protection, developing special industries which are friendly to resources and environment and appropriate for local conditions, guiding and encouraging industries to learn from regions with favorable development conditions, orderly withdrawing industries and enterprises adverse to main functions, facilitating industrial structure upgrading, optimizing industrial organization, improving industrial technological level and rationalizing industrial layout.展开更多

Odorants generate different changes in the concentrations of oxy- hemoglobin. Our results suggest that NIRS technology might be useful in discriminating various odorants in a non-invasive manner using animals with a superb olfactory system.展开更多
