With the globalization of world economy,na- tional sovereignty is changing.Our country is now confronted by three major challenges: the independence of economic sovereignty,the integrity of political sovereignty and the equality of cultural sovereignty. This research probes how to maximize national benefits under globalization.展开更多

The results show that the primary fluid inclusions contain vapor and liquid phase type (Type I), daughter mineral-bearing type (Type II) and pure liquid phase type (Type III). The compositions of vapor are mainly H20 and CO2 with a tiny amounts of CH4 and H2; the liquid phase mainly contains Mg2+, Ca2+, Na+, K+, CI- and SO]-, and w(Na+)/w(K+)〉l; the homogenization temperatures of the primary fluid inclusions can be divided into 190-250 ℃, 250-340 ℃ and 360-420 ℃, corresponding to the salinities of 4%-9%, 9%-14%, and 14%-20.43% (NaC1 equivalent mass fraction), respectively. The mineralization process can be divided into three episodes: the silicatization stage, the quartz-sulfide stage, and the carbonatization stage, and all of them are associated with the ore-forming hydrothermal fluid activity. The origin of the hydrothermal fluid is from magrnatic water mainly, and later it mixes with the groundwater and meteoric water, which lead to the decrease of temperature and salinity. The decrease of salinity, temperature and pressure are the main causes of the metallogenic elements unloading and enriching in the favorable position.展开更多

However, the inherent urban and rural differences and path dependence determines the integration of urban and rural low-cost integration is far from the standard can be achieved, the institutional environment and the operating environment are not in the same starting line of the facts, determines the "integration" will need to go through a long period of time Time of urban and rural development can be gradually achieved.
