The Yuanmou Basin of Yunnan Province is a hotspot for the research of early homind evolution and its environmental background.During the implementation of the Program“Research of the Origin and Evolution of Early Man and Its Environmental Baqckground” from 1998 to 2001,a huge quantity of hominoid and mammal fossils were collected.The present report systematically describes an Euprox robustus sp.nov.identified during the recent laboratory work on the collected material.Euprox is a group of earliest cervids with true antlers.The new species is the third one of the genus discovered in China.Judged by its morphologic characteristics,the new species feed on juicy and tender leaves of dicotyledon.It implies that the vegetation of its epoch in the Yuanmou Basin is a kind of southern subtropical evergreen forest and the climate is humid and temperate with evident seasonality.The latter is mostly influenced by the monsoon and secondly by the latitude.  相似文献

Shakespeare,the colossus in English literature,writes thirty-seven world-famous plays as well as one hundred and fifty-four universally appreciatedsonnets during English Renaissance period.His sonnets are the crystallization of his deep thought and his perfect art.Sonnets127-154 are addressed to a dark-skinnedwoman.This woman is not a fashionable beauty,but she is very attractive.Also she is dissolute in nature and experienced in loving affairs.The sonnets are focused on the entanglement between the poet and her.His point of view towards the woman is contradictory:he praises his deeply loving girl,and at the same time he blames her disloyalty.  相似文献

Graham Greene is one of the most important English writers in the 20th century.In Greene’s novels,readers easily find a literary world which is a dark land filled with violence,guilt,corruption and other forms of evil."The Destructors"also reflects this theme.Being interested in the story and the teenagers’growing-up,the author starts this paper-An Analysis of the theme and the characters in"The Destructors".First of all,this paper discusses the reasons that cause the gang to make destructions.The children are so violent;it has its intangible needs.It gives a new view to think about the children’s heart and makes us to recognize what the war left to people,especially to the children.And then,based on the analysis of the theme and characters,this paper discusses that the characters and their actions project the theme to a great extent,and that the teenagers’psychology and actions are greatly determined by their surroundings,which should be reconsidered by instructors.The moral and character education should gain a good deal of enlightenment from it.  相似文献

A new kind of fuzzy control scheme, based on the identification of the signal‘ s main frequency and the behavior of the ER damper, is proposed to control the semi-active suspension system. This method ad-justs the fuzzy controller to achieve the best isolation effect by analyzing the main frequency‘ s characters and inspecting the change of system parameters. The input of the fuzzy controller is the main frequency and the op-timal damping ratio is the output. Simulation results indicated that the proposed control method is very effec-tive in isolating the vibration.  相似文献

The traveling salesman problem (TSP) is a classical optimization problem and it is one of a class of NP- Problem. This paper presents a new method named multiagent approach based genetic algorithm and ant colony system to solve the TSP. Three kinds of agents with different function were designed in the multi-agent architecture proposed by this paper. The first kind of agent is ant colony optimization agent and its function is generating the new solution continuously. The second kind of agent is selection agent, crossover agent and mutation agent, their function is optimizing the current solutions group. The third kind of agent is fast local searching agent and its function is optimizing the best solution from the beginning of the trial. At the end of this paper, the experimental results have shown that the proposed hybrid ap proach has good performance with respect to the quality of solution and the speed of computation.  相似文献

The development of venture capital has drawn much attention, and many qualitative analysis and discussions have been proposed. A quantitative model is proposed based upon Reputation Model. The present compensation structure of U. S. venture capital limited partnerships is analyzed and a kind of new compensation structure is proposed. The relations between the venture capitalist' s effort level and the two compensation structures are given . The comparison of analytical results proves that the present compensation structure in U.S. may not be the best choice, and that the proposed one can give a better motivation for venture capitalist's management action.  相似文献

We present two recent methods, called UTAGMS and GRIP, from the viewpoint of robust ranking of multicriteria alternatives. In these methods, the preference information provided by a single or multiple Decision Makers (DMs) is composed of holistic judgements of some selected alternatives, called reference alternatives. The judgements express pairwise comparisons of some reference alternatives (in UTAGMS), and comparisons of selected pairs of reference alternatives from the viewpoint of intensity of preference (in GRIP). Ordinal regression is used to find additive value functions compatible with this preference information. The whole set of compatible value functions is then used in Linear Programming (LP) to calculate a necessary and possible weak preference relations in the set of all alternatives, and in the set of all pairs of alternatives. While the necessary relation is true for all compatible value functions, the possible relation is true for at least one compatible value function. The necessary relation is a partial preorder and the possible relation is a complete and negatively transitive relation. The necessary relations show consequences of the given preference information which are robust because “always true”. We illustrate this methodology with an example.  相似文献

Diagnosis and prediction of satellite fault are more difficult than that of other equipment due to the complex structure of satellites and the presence of muhi-excite sources of satellite faults. Generally, one kind of reasoning model can only diagnose and predict one kind of satellite faults. In this paper the author introduces an application of a new method using multi-modal reasoning to diagnose and predict satellite faults. The method has been used in the development of knowledge-based satellite fault diagnosis and recovery system (KSFDRS) successfully. It is shown that the method is effective.  相似文献

William Faulkner’s style of works earns the popularity of the modem stream of consciousness technique. A Rose for Emily is one of his most impressive short stories, whose theme may challenge readers to work out from different perspectives. This paper mainly presents a psychoanalytical account of the reflections of its theme by way of the social and psychological conflicts between erotic passions and human cruelty portrayed in the story.  相似文献
