| 1 | The characteristics of atmospheric CO_2 concentration variation of four national background stations in China显示文摘Atmospheric carbon dioxide is an important kind of greenhouse gas which influences global temperature. Its concentration variation could indicate the distribution of human and natural activities in various regions. Through the non-dispersive infrared method, flask sampling of atmospheric CO2 concen- tration was measured weekly at four national background stations including Waliguan, Shangdianzi, Lin’an, and Longfengshan. Based on the data collected from September 2006 to August 2007, along with the Waliguan station’s experience on in situ observational data processing, the selection methods for sampling data through the atmospheric background CO2 concentration analysis were preliminarily discussed. On the basis of this result, the variation features of the four typical regions’ atmospheric background CO2 concentration was analyzed for the first time. The results show that the atmospheric CO2 concentration at Waliguan, Shangdianzi, Lin’an, and Longfengshan is 383.5, 385.9, 387.8, and 384.3 ppm, respectively. During the research period, CO2 concentration at the Waliguan station changed slightly. However, the CO2 concentration changed sharply at the Shangdianzi and the Lin’an stations due to the great influence of human activities in the Jingjinji and the Changjiang Delta economic zones, and changed regularly with seasons at Longfengshan station under dual influences of human activities and plant photosynthesis. The results from this study can lay the foundation for more profound studies on atmospheric CO2 concentration level of different areas in China, and could be used to improve the understanding of carbon source and sink distribution. | LIU LiXin, ZHOU LingXi, ZHANG XiaoChun, WEN Min, ZHANG Fang, YAO Bo & FANG ShuangXi Key Laboratory for Atmospheric Chemistry, Centre for Atmosphere Watch and Services (CAWAS), Chinese Academy of Meteoro- logical Sciences (CAMS), China Meteorological Administration (CMA), Beijing 100081, China | 2009 | Science China Earth Sciences2009，52，11： | 26 |
| 2 | Modeling the impact of Australian Plate drift on Southern Hemisphere climate and environment显示文摘Using a global atmosphere-ocean coupled model with the present-day and 14 MaB.P. oceanic topogra- phy respectively, two experiments are implemented to inves- tigate the effect of different locations of Australian Plate on the atmospheric circulation in middle-high latitudes of the Southern Hemisphere. The results show that when Austra- lian Plate lay south at 14 MaB.P., both anticyclone circula- tions in the subtropical oceans and cyclone circulation around 60°-70°S are strengthened. Subtropical highs and circumpolar low pressure appear stronger, which results in much stronger Antarctic Oscillation and shorter period of Antarctic Oscillation Index (AOI) at 14 MaB.P. The rainfall and the surface air temperature also change correspondingly. The precipitation decreases around 40°S and increases around 60°-70°S, and the surface air temperature rises in high latitudes of the South Pacific and descends over the Weddell Sea and its north side. Besides, due to the changes of the temperatures and winds, Antarctic sea ice coverage also changes with its increasing in the Ross Sea and its west re- gions and decreasing in the Weddell Sea. | ZHOU Botao1,5, ZHAO Ping2, JIAN Zhimin3 & HE Jinhai4 1.

| 3 | Experimental study on the P wave velocity in rocks from lower crust and crust-mantle transitional zone beneath the Hannuoha显示文摘Cenozoic basalt-borne mafic granulite-facies plagioclase pyroxenite and eclogite-facies garnet pyroxenite xenoliths from the Hannuoba, as well as nearby Archean terrain granulites, are selected for the experimental study on the P wave velocity at high temperature and high pressure in order to reveal the present-day compositional features for the lower crust and crust-mantle transitional zone. Results show that mafic xenoliths have high Vp (7.0~8.0 km/s), in contrast, the Archean terrain granulites have low Vp (<7.0 km/s). High Vp mafic xenoliths can represent the present-day compositional features for the lower crust and crust-mantle transitional zone beneath the Hannuoba. This provides new evidence for the crust vertical growth and the formation of the crust-mantle transitional zone resulting from the magma underplating. Low Vp Archean granulite still remains the characteristics of the early lower crust. | FAN Qicheng SUI Jianli ZHANG Hongfu ZHAI Mingguo and XIE Hongsen(1.

| 6 | A method for solving Nash equilibria of games based on public announcement logic显示文摘Describing the interactional behavior of rational agents and seeking equilibria are two main domains of game theory. The epistemic foundation of the above two domains is based on the assumption that all players are rational. However, game theory itself cannot precisely model the higher-order information changes of mutual knowledge among players, so in the current studies of game theory the interpretations of rationality are vague. In this paper, a concept of the rationality is redefined through incorporating an epistemic ingredient. Then a method is proposed to solve and refine Nash equilibria which is grounded on public announcement logic, and it is proved that the iterated announcement of this rationality assertion characterizes the iterated admissibility algorithm in game theory, which offers a dynamic epistemic foundation for this algorithm. Finally, an implementation of this method, based on the extended DEMO, is shown to be correct. | CUI JianYing & TANG XiaoJia Institute of Logic and Intelligence, Southwest University, Chongqing 400715, China | 2010 | Science China(Information Sciences)2010，53，7： | 2 |
