Over the past 50 years, Chinahas experienced a dramaticturn in its petroleumproduction. Today, our country isfacing the same challenge it met 50years ago. Therefore, we have torenew our once high vigor to seekmore petroleum deposits in order tomeet the needs of national develop-ment in the new century.Before the founding of thePeoples Republic of China in 1949,China was looked on as a countrywith few petroleum reserves. Sincethen, oil explorers painstakinglycombed the plains, wilderness ando…  相似文献

Engineering nano-materials & their impact on human health or environmental security constitute a newly emerging R&D hot spot and a key problem now urgently waiting for its solution in supporting the sustainability of China’s nano-science and related technology development. At present, water bodies in Chinese cities have been seriously polluted by metallic nano-particles (MNPs) while related monitoring data are found woefully lacking throughout the country. Based on the above understanding, this article gives a round-up explanation on distributive characteristics of MNPs in the river mouths or water bodies of Chinese cities, their ecological hazards as well as our research in this regard, providing some inspiring ideas and data for control over this scourge. In addition, our exploration probes the discharge traits of MNPs themselves and the mechanism underlying its impact on water pollution.  相似文献

The temperature of the upper reaches of theYellow River, the second longest river in China,is clearly related to the worldwide warmingtrend, according to a study conducted by CAS research-ers and their colleagues from Administration of Hy-drology and Water Resources of the Upper Reaches ofthe Yellow River. They warn that, due to the possibletemperature hike and drastic decline in localprecipitation, the runoff in the reaches may face a trendof continued decrease over the next decade.The p…  相似文献

Noodles have been a popu-lar staple food in manyparts of the world for atleast 2,000 years, although it is de-batable whether the Chinese, theItalians or the Arabs invented themfirst. A recent study by CAS re-searchers and co-workers fromhome and abroad reveals that thepreparation of boiled noodles wasalready invented in China about4,000 years ago. The work was re-ported in the October 13 issue ofthe journal Nature.Prior to this finding, the earli-est record of noodles only appearedin a bo…  相似文献

The act of indirect/contributory infringement of patent is relative to the act of direct infringement of patent.The con- ception of indirect/contributory infringement of patent is,to a large extent,to meet the practical need for the protection of the patent right.In practice,to avoid liability for patent in- fringement,one sometimes does not exploit all,but only some,technical features defined in a claim of a patent,or several people jointly exploit all the technical features of the claim.According to the All Elements Rule in determination of patent infringement,if an accused article does not cover all  相似文献

Lichens are believed to playa pioneering role in trans-forming the earth surfacewhen they appeared on land hun-dreds of million years ago, pavingthe way for the evolution of terres-trial plants and animals. But mosthabitats where lichens dominate,such as tundra, mountains, anddeserts, have a very low chance ofpreserving fossils. Until recently theearliest known lichen fossils werediscovered in 1995 by Thomas N.Taylor, a University of Kansasresearcher, from 400 million-year olddeposits in Sco…  相似文献
