The modern technology give a chance for the pattern of transmitting knowledge with network, the course based on network have opened up it ' s way in china, our pursuer paid more attention to the mode, but in america, pursuer have studied the more width aspect, thereinto the investigation and design of the information in the course based on network is very important, for the design of the information decide the pattern how the student receive the information, which will effect the way of knowledge understanding and memory, and the way is related to the study pattern, so the design of the information in the course based on network is very important to the efficiency and effect. so the core of the paper is the investigation and design of the information in the course. i have the entropy from the information science as the analyse tool to analyse the information, these work tell us the efficient pattern to transmit information, based on the result, i design the net page, of course, study theory and the character of the net itself are also the factors i employ for design a good net page. then, links and navigation is constituted for students adapt to the course based on network
當今技術的發展給知識以網路為媒介來傳播的學習方式帶來前所未有的機遇,網路課程在國內迅速開展起來,但是國內研究者的注意力主要集中在對網路課程模式的探索上,放眼國外,他們的研究觸角已經涉及到網路課程比較細致的方面,尤其是對網路課程信息的研究構成了國外網路課程研究中的比較重要的一個方面,而網路課程中信息的設計是重要的,因為信息的組織設計是為了接受者能對信息進行有效的信息加工,信息的呈現模式影響著學習者對知識的理解和記憶方式,進而決定了學習者的學習模式,因此網路信息的設計在網路課程傳遞的效
率和效果中就佔有很重要的位置。基於這個觀念,本文把網路信息的組織設計作為研究的重點,引入了信息科學作為研究的主要工具對網路中的信息作以量化分析研究,主要應用了信息科學中信息
熵的公式進行推導,得到學習內容信息組織的基本模式,並充分利用網路自身特性和學習理論對知識信息進行細致的設計,此外還對鏈接和導航信息進行了設計,在網路課程的適應性方面作出了努力,把交互信息與輔助學習信息的分析設計與應用和對網路頁面信息的總體調節優化作為主體信息設計部分的補充,最終形成了網路信息組織設計的方案,力求創設一個能夠有效傳遞知識信息,減少網路自身弊病,並帶有一定適應性的網路學習環境,也使更多的網路課程的設計者關注網路信息這個因素。
It has been shown that : the little indentation which represents the quantum noise of the system appears in the evolution curves ; the quantum noise which is caused by virtual photon field gradually becomes weak when w increases, the quantum noise increases when n increases ; the virtual photon process make the antibunching effect strengthen, make the squeezing degree deepen obviously, and lead to the additional vibration of entropy, the oscillation extent of the additional vibration of entropy increases when n increases and decreases when co or g increase. besides, the quantum dynamics of two coupling atoms interacting with a single mode ligh t field in a kerr medium is studied in this paper ; the influences of the kerr effect on the mean photon number, the degree of second order coherence of field, the evolution of the field entropy and the squeezing effect are also discussed

In this paper, management entropy theory and its integrated evaluation system was introduced into enterprises ’ human resource and its management evaluation process, and we revealed the law of the decrease in the efficiency of human resources management systematically when enterprises ’ human resource and its management were under a closed system ; but in an open system, because of the exit of management dissipation and dissipation structure, human resource management system exchange materials, energy and information with the outside world constantly, the rule makes negative management entropy and management entropy showed shiftily in an enterprise
