The vehicle - carried communication system is the one which equips vehicle with advanced communication technology 車載通訊系統(tǒng)是指裝載在車輛上的移動通訊系統(tǒng)。
In the more than 10 years development process of china ’ s telecommunications market reform , with the government policy guidance and support , the entire telecommunications industry rapidly developed , he scale of users rapidly expanded , the most advanced communication technologies was used , fee levels continued to decline , and the quality of services were significantly enhanced . domestic telecommunications market has experienced a series of reform measures , including inducing competition , dividing the corporate from the government , and restructuring corporate , and has scored brilliant achievements and made tremendous contributions in the development of the national economy 本文以有效競爭理論、規(guī)制理論為理論基礎,從我國電信改革客觀實際出發(fā),對國內(nèi)電信市場競爭模式的轉(zhuǎn)變過程進行了分析,并與國外競爭模式轉(zhuǎn)變情況進行比較,分析了競爭模式轉(zhuǎn)變過程中的產(chǎn)權(quán)改革問題,建立定量模型對競爭模式轉(zhuǎn)變過程中資源配置效率進行了系統(tǒng)的研究,提出了我國電信市場競爭模式選擇的系列建議。
I warmly congratulate you on the publication of telecommunications construction and hope that it will introduce to the readers information about the development of china ' s information and communications industry and the development and application of advanced communications technology and make contributions to the cultivation of young professionals and the exchange and cooperation between colleagues in the information and communications circle 熱烈祝賀《電信建設》創(chuàng)刊,希望《電信建設》向廣大讀者介紹中國信息通信產(chǎn)業(yè)的發(fā)展、先進通信技術的開發(fā)與應用,在促進通信科技人才的成長和進步、增進信息通信界同行之間的交流與合作方面作出有益的貢獻。
The system adopts mature and advanced communication technology to make the centralized controls distributed on the network . it allows users to be able to monitor detailed status of the ups , the leaking , the air conditioning , the video capturing , the electric power supplying and the access switching in the central control room conveniently 系統(tǒng)采用成熟先進的技術,實現(xiàn)了在計算機網(wǎng)絡上的集中分布監(jiān)控,使用戶可以方便地監(jiān)控機房內(nèi)ups漏水空調(diào)視頻配電及機房門狀態(tài)等具體情況,將各種報警信息及時的通知相關的管理人員,從而有效地進行機房管理。
Distributed control system ( dcs ) makes system function distributed , rank by using micro computer . it keeps closed relation and coordinated action between every sub system and control center by using advanced communication technology . it has many advantages for example high reliability , high flexible , and powerful system function 分散型控制系統(tǒng)( dcs )利用微型計算機使系統(tǒng)的功能分散化、階層化,采用先進的通訊技術,使各子系統(tǒng)與控制中心保持密切的聯(lián)系及進行協(xié)調(diào)動作,它具有可靠性高、靈活性大、系統(tǒng)功能強等優(yōu)點。
