The outer surfaces of eggshell fragments from Gashunyinadege are smooth with a sting pore pattern, while their entire thickness is around 2.12 mm. In a cross-sectional view, the surface crystal layer is very thin and the ratio of cone layer to the those from Gashunyinadege, but seem much thinner and have a lower pore density. Both characteristics fit aepyornithid-type eggshells, implying that the distribution of aepyornithid-type eggshells can be extended to East Asia. The sediments at Gashunyinadege date to approximately 17.5 Ma, implying that the specimens from this locality are relatively early examples of aepyornithid-type eggshells. Aepyornithidtype eggshells seem to have appeared in Eurasia much earlier than struthionid-type eggshells. The faunal compositions in the two localities reflect gradual drying of the Mongolian plateau during the Miocene. A reduction in the number of pores 10 Ma ago, probably occurred in response to this drying process.展开更多

Middle Holocene climate and sea level change on North China coast were correlated to warm marine environment events in about 8–3 ka B.P. The sea level in about 8 ka B.P. was higher than present mean sea level, then fluctuated for 5 000 years and after that it became even in 3 ka B.P. The highest sea level occurred in about 6–5 ka B.P.; the maximum was about 2–3 m and minimum was about 1–2 m.展开更多

Nations are scrambling to gain greater influence. The intemational strategic pattern is being adjusted. Many countries have problems with public management, and are faced with a new array of social trends and increasingly popular movements. The world is entering a new era full of chaos and anxiety. Mankind once again faces significant trade-offs and choices in peace and conflict, development and recession, openness and isolation, liberalism and conservatism. China strives to advocate win-win cooperation and lead the trend of reform and opening to maintain a favorable external environment despite world chaos, and enhance status and institutional fights in the international system. China＇s 30 years of development was successful in the process of integrating into the existing international system; China is a participant as well as a builder of the international system, rather than a challenger or a subversive. In the future, with a constructive attitude, China will promote the international system in a more reasonable direction together with international partners, in order to better safeguard world peace and security, and promote sustainable development throughout the world.展开更多

It would be very difficult to identify a causal relationship between the two imbalances. In any case, this is an outcome of the past few decades. The same situation can also befound in other countries. Where are China＇s economy and its reform heading towards？ At the macro-level, the econmnic policies guiding China＇s economy and its performance are closely related to the two imbalances. One thing is for certain： world economic equilibrium will help balance various economies including China. But the world economy cannot automatically balance itself. Various economies must restore their balance before equilibrium can be achieved at the global level. For individual countries, balancing their domestic economy is what they can concentrate on. In other words, China needs to rely on its own efforts to achieve internal economic balance through reform. Internal econontic balance will promote sustainable development and contribute to the world economic balance. The questhm is where will such internal balance come from？ How can China achieve an internal rebalance？展开更多
