The origin of metallogenic hydrothermal fluids was studied through simulating REE pattern of the balanceable hydrothermal fluids. The results indicate that the metallogenic materials come from the diorite and the metallogenic hydrothermal fluids come from the dioritic magma. The results also show that the rare earth elements are relatively mobile during metallization.展开更多

The structure of mixed TC 16 PyP(4)/AnQ LB films was characterized by π A isotherms, UV Vis absorption spectra and low angle X ray diffraction(LAXD). The experimental results indicate that the TC 16 PyP(4)/AnQ mixture can form a stable monolayer on the air/water interface. Most AnQ molecules are incorporated into the cavities between the long alkyl chains of TC 16 PyP(4) molecules in the mixed monolayer and LB films. Mixed TC 16 PyP(4)/AnQ monolayer can be transferred to the substrates. TC 16 PyP(4)/AnQ LB films have a good stability and periodicity. [WT5HZ]展开更多

However, the maintenance of urban ecological security, scientificity, integrality and continuity of ecosystem, as well as scientificity of the defining methods and the effective supervision of the basic ecological control line have become bones of contention. This paper, from the perspective of "anti-planning", synthesized the theories and methods such as urban-rural planning, ecology and GIS, coupled ecological sensitivity assessment and ecological security pattern to define the basic ecological control lines of the planning area in Anqing City. The basic ecological control line area includes ecological baseline area and ecological development area. Management and control strategies of basic ecological control line were elaborated from the following aspects: implementation of the basic ecological control line, protection and utilization of ecological resources within the lines, solutions to existing construction land within the lines, adjustment mechanism and implementation guarantee mechanism of basic ecological control line.展开更多
