Numerical weather prediction (NWP) has become one of the most important means for weather forecasts in the world. It also mirrors a nation's comprehensive strength in meteorology. In 2000, China Meteorological Administration (CMA) established the National Innovative Base for Meteorological Numerical Prediction in the Chinese Academy of Meteorological Sciences (CAMS), to work on developing a new generation of the national operational NWP system-Global/Regional Assimilation and PrEdiction System (GRAPES), to enhance meteorological services in China in the new century. In recent years, the GRAPES has witnessed a fast development. The GRAPES has been set up as an integration of the model framework, data assimilation, regional and global NWP system, which can be commonly used for both operation and research. In this paper, a brief review is made for illustrating the GRAPES system, including the advanced designs of the GRAPES, its diverse applications in multi-fields, and efficiencies of the regional and global GRAPES in operational applications based on hindcast results.  相似文献

Owing to the influences of Greek's view of fate, Dorset peasant's fatalism and Schopenhauer' s pessimistic philosophy, Hardy showed more or less a pessimistic tendency in his early writings and this tendency illustrated itself in his writing of Eustacia, heroine of The Return of the Native. He believed that Eustacia' s tragedy resulted from the disagreement between her aspiration for a brilliant life outside Egdon Heath and the fate imposed on her by some mysterious force working at odds with her. This is what the paper attempts to prove.  相似文献

This essay analyzes the famous French writer's novel Candide from the perspective of gender roles. It introduces some literary terms related to gender, and explains my understanding of the gender roles some characters have played from the aspects of wars and masculinity, Candide and masculinity, female characters and femininity, and Candide related to feminism.  相似文献

The cooperation of multi-robot that is based on the multi-agent system (MAS) theory of distributed artificial intelligence has become a hotspot in the robotics R&D. In the research the multi-robot is regarded as multi-agent. So the communication and cooperation of multi-agent become the key problem for gaining the dynamic running information of cooperating robots. In this paper the authors introduce the communication modes for agent and provide a common strategy which aims at the communication resources of multi-agent model-the CSMA/CD (Carrier Sense Multiple Access with Collision Detection) protocol which is based on the transmittal medium. It supports the cable-communication of multi-robot and the experiments prove its validity.  相似文献

The methods to enhance the heat transfer in heat exchanger may be classified into two levels: one is to improve the heat transfer coefficient; the other is to upgrade the whole arrangement of the heat exchangers. For the second level, the performance of heat exchanger can be upgraded by increasing the coordination degree between the temperature fields of cold and hot fluids. When the temperature distributions are similar to each other, the temperature difference field (TDF) is more uniform, which means that the temperature fields are more coordinated with each other. For the cross-flow heat exchanger, rearrangement of the heat exchange surface area should improve the heat transfer effectiveness, which is even equal to that of the counter-flow heat exchanger when the surface area is reassigned optimally. For the multi-stream heat exchanger, the thermal performance is also dependent on the uniformity of the TDF, and the parallel-flow arrangement may achieve higher heat exchange effectiveness than the counter-flow arrangement, which indicates that the performance of heat exchanger depends on the coordination degree of temperature fields instead of the flow arrangement.  相似文献

Discussions on the age of the Daohugou fauna—evidence from invertebrates   总被引:6,自引:0,他引:6  
Volcanic tuff deposits near Daohugou village, Ningcheng County of Inner Mongolia have yielded many wellpreserved fossils. Here we briefly introduce our recent findings of invertebrates from the Daohugou fauna: mainly insects, conchostracans, anostracans, and spiders. The age of the Daohugou fauna is considered to be Middle Jurassic on the basis of an analysis of various invertebrates especially insects and conchostracans, showing strong similarities to the Yanliao fauna of north China and the Karatau fauna of Kazakhstan.  相似文献

From the relationship between culture and language,we know language is a carrier of culture;each nation has its own distinctive culture.Through comparing cultural connotation between Chinese characters and English words,we know it is more important for us to master the cultural connotation of words than just knowing their spelling and pronouncing.Only under this condition,we can use English properly and freely.  相似文献

Based on the measured activities,the phase diagrams and the annexation principle,the calculating models of mass action concentrations for Ag-Bi and Ag-Bi-In melts have been formulated.The calculated results agree with practice and obey the mass action law,showing that the models formulated can reflect the structural characteristics of both melts.Meanwhile,it confirms that annexation principle is applicable to the Ag-Bi-In metallic melts.The melts involving eutectic which give rise to phase separation,and in which activcities exhibit positive deviation from Raoult‘s law is the basic cause of melts transforming from homogeneous to heterogeneous ones.  相似文献
