Incompatible element vs. incompatible element diagrams display smooth positive trends for the Tianshan Carboniferous rift-related volcanic rocks; the isotope ratios of the silicic lavas [^87Sr/^86S(t)=0.699880.70532; eNd(t)=4.76-8.00; ^206pb/^204pb(t)=17.435-18.017; ^207Pb/^204Pb(t)=15.438-15.509; ^208Pb/^204Pb(t) = 37.075-37.723] encompass those of the basic lavas. These data suggest a genetic link between rhyolites and basalts, but are not definitive in establishing whether silicic rocks are related to basalts through fractional crystallization or partial melting. Geochemical modeling of incompatible vs. compatible elements excludes the possibility that silicic melts are generated by the melting of basaltic rocks, and indicates a derivation by fractional crystallization plus moderate assimilation of wall rocks (AFC) starting from intermediate rocks to silicic rocks. Continuous AFC from basalt to rhyolite, with small rates of crustal assimilation, best explains the geochemical data. The presence or absence of bimodal volcanism (the "Daly Gap") might be related to cooling rates of magma chambers. In central and eastern Tianshan, the crust was thinner and the cooling rates of the magma chamber within the crust were greater. These conditions resulted in a rapid fall in temperature within the magma reservoir and caused a narrow temperature interval over which intermediate melts formed, effectively reducing the volume of the intermediate melts.展开更多

Based on an analysis of some official and nonofficial research reports published in the United States,this article holds that the China-U.S.trade imbalance is the symptom of a bigger issue stemming from the contradiction between the United States as the world's sole superpower and China as an emerging power.Economic globalisation came about due to the needs of western developed countries represented by the United States to boost economic development.Only by seizing the opportunities of economic globalisation, has China gained strong economic growth. Such a development is changing the world political,economic,military and cultural landscape that have been shaped since the post-cold-war era,and has to some extent raised doubt or suspicion on the part of the United States and its western allies.This is a manifestation of how unprepared some people in the United States and other western countries are in the face of China's rapid development and rising status.So,their immediate reaction has been to seek protection for themselves,and try their utmost to prevent China's rapid growth from impacting on the international framework and their vested interests.展开更多

Since the"nationalization"of the Diaoyu Islands by Japan in 2012, mutual trust between China and Japan has been declining, and bilateral security relations have reached a low point. China-Japan security relations are typified by ongoing dispute over the Diaoyu Islands, lack of mutual trust exacerbated by various actions by Japan, and the delay of China-Japan security dialogues. The evolution of China-Japan security relations derived from the Diaoyu Islands dispute is clearly beyond the scope of the dispute itself, with deep-rooted internal and external factors. In the near future,China-Japan security relations will face more challenges than opportunities. China should take measures, including enhancing mutual trust in politics and security between the two countries, to impose necessary pressure on Japan to change course, to win over neighboring countries so as to avoid pretext for Japan's intervention in regional issues,and to strengthen interpersonal communication and understanding between people of the two countries in order to stabilize security relations.展开更多
