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。Finally, we can not use electric power but the engine of bus or subsidiary engine to drive air compressors of bus air conditions. because the change range of turnaround speed of engine is very wide, that brings difficulties in controlling the rate of flow of cold - producing medium. in the control of bus air - conditions, preventing evaporator from freezing to make the air - conditions work with high efficiency and controlling the temperature of railway carriage are the basic tasks in air - condition control
與一般的建築空調相比，汽車空調的工作環境惡劣，條件差，控制難度要增加很多，主要體現在以下幾個方面：一是車外熱負荷變化大，難以確定控制參數；二是要求空調負荷大，而且要控制空調使其降溫迅速：三，不便於用電力作為動力源，必須用汽車發動機或輔助發動機來帶動壓縮機，當採用汽車發動機作為動力源時，由於汽車的車速變化大，發動機轉速的變化可從600r min到4000r min ，壓縮機轉速與發動機轉速成正比，其轉速變化高達7倍，給空調系統製冷劑流量控制帶來困難。Firstly, by an in - depth study on chinese commercial banking and their foreign counterparts, this paper points out the great differences of intermediate business innovation between chinese and western commercial banks regarding innovation products variety, scale, technology, etc. secondly, comparing the institution regarding intermediate business innovation and microeconomic - body behavior of chinese commercial banking with foreign ones within an analysis framework from the perspective of institutional economics and game theories, this paper shows that a number of reasons account for the emerging of intermediate business innovation, including external economic environments as well as internal factors within the financial system and technology, among which the institutional factors within the financial system being the most important. at the same time, by comparison with western developed countries " counterparts, the innovation of chinese banking institution lags far behind the development of banking business in main aspects of property rights, managerial system, compensation arrangement and organization system. thus, the backward innovation of banking institutions and twisting microeconomic - body behavior seriously strict intermediate business innovation
