Of the total, exports topped US$266.16 billion, 6.8% up over the previous year, imports reached US$243.61 billion, up 8.2%, and accumulated trade surplus climbed to US$22.55 billion. The results were fairly outstanding if we take a general look at the world economy, which experienced significant slowdown in 2001 mainly due to the serious downturns in the United States and Japan. The increase can be attributed to a number of factors including the rise展开更多

An essential element for continued economic prosperity is a water supply of guaranteed quality and quantity, providing critical insurance for food safety, health, and political stability. However, China＇s economic success has come with serious water resources problems, intensified by human activities and climate change. The nation is now facing extreme levels of water pollution, soil erosion, and sedimentation, along with floods, droughts, and urban storms. Taken together, these impacts have provided a serious headwind to socioeconomic development in China. This article discusses the problems and emerging opportunities for the coming generation of water scientists and engineers.展开更多

However, the exploration of these shales is presently at a relatively immature stage. The Upper Paleozoic shales in the northwestern Guizhong Depression, including the Middle Devonian Luofu shale, the Nabiao shale, and the Lower Carboniferous Yanguan shale, were investigated in this study. Mineral composition analysis, organic matter analysis(including total organic carbon(TOC) content, maceral of kerogen and the vitrinite reflection(Ro)), pore characteristic analysis(including porosity and permeability, pore type identification by SEM, and pore size distribution by nitrogen sorption), methane isothermal sorption test were conducted, and the distribution and thickness of the shales were determined, Then the characteristics of the two target shales were illustrated and compared. The results show that the Upper Paleozoic shales have favorable organic matter conditions(mainly moderate to high TOC content, type Ⅰ and Ⅱ_1 kerogen and high to over maturity), good fracability potential(brittleness index(BI) > 40%), multiple pore types, stable distribution and effective thickness, and good methane sorption capacity. Therefore, the Upper Paleozoic shales in the northern Guizhong Depression have good shale gas potential and exploration prospects. Moreover, the average TOC content, average BI, thickness of the organic-rich shale(TOC > 2.0 wt%) and the shale gas resources of the Middle Devonian shales are better than those of the Lower Carboniferous shale. The Middle Devonian shales have better shale gas potential and exploration prospects than the Lower Carboniferous shales.展开更多

It is expected that the total volume of the world’s commodity trade will reach US$5.6 trillion in the year 2000; and this figure will rise to US$10tillion in 2010. The development trend in commodity composition shows that the trade volume of manufactured goods continues to expand, the market for primary goods is declining, and mechano-electrical products, especially high-value technical products, will be the items with the highest predicted growth in展开更多
