頻散媒 的英文怎麼說
中文拼音 [bīnsǎnméi]
頻散媒
英文
dispersive medium-
Vod ( video on demand ) system can be widely used in many fields, such as long distance education, digital library, news on demand, tv on demand and etc. video server is the key part of vod system, whose performance has direct effect on the service quality of vod system
視頻點播系統可以廣泛地應用於遠程教學、數字圖書館、新聞點播、電子商貿、電視點播等文化、商業及娛樂的各種領域，具有很高的實用價值。視頻服務器（ videoserver ）是視頻點播系統中最關鍵的組成部分，它的性能直接影響視頻點播系統所提供的服務質量，因此視頻服務器的設計是分散式多媒體領域的重要研究課題。Then, the auxiliary fields fdtd is used to the periodic structure made of dispersive material, such as the pyramid absorbers in anechoic chamber. the permittivity vs frequency property of the absorber is approached by some dispersive equation model, such as debye model and lorentz model, so the broadband response of the absorber can be gotten through one calculation
然後將輔助場fdtd應用到色散媒質周期結構中，導出了色散媒質中的迭代式，並以暗室吸波材料陣列為例進行計算，提出用某一類型的介電常數色散函數（如debye型、 lorentz型等）來逼近材料的介電常數頻率特性的方法，從而可以對吸波材料進行一次性寬頻計算。Distributed multimedia applications such as videoconference, video on demand, long - distance education, automatic monitor system etc. are slowly coming into people ' s life. they also bring much facilities and fun to people ' s work and life
視頻會議，視頻點播，遠程教育，無人監控等分散式多媒體應用逐漸走入人們的生活，給人們的工作和生活帶來了極大的便利和無窮的樂趣。The discourse describes the architecture and implementation of the collaboration framework. it provides a distributed architecture for collaboration using synchronous communications like multimedia conferencing, instant messaging, shared web - browsing and asynchronous communications like discussion
該框架為同步通信和異步通信提供了分散式的體系結構，同步通信包括:多媒體會議，即時消息，共享web瀏覽等等，異步通信包括:論壇，共享文件，語音和視頻郵件等等。With the rapid prevalence and explosive development of internet, there have been many new applications such as the network conferencing, the update of distributed database, distributed database exploitation, cscw, etc, transmitting information of these applications will deal with not only the point to point way but also the ones that will be much of the video frequency and sound frequency, this produces new challenges for traditional routing selection mechanism
隨著internet的迅速普及和爆炸性發展，在網路上產生了許多新的應用，如網路會議、分散式資源發現、分散式數據庫開發等，這些應用不再是簡單的點對點的文本信息傳輸，而是一般需要傳輸大量的音頻、視頻等多媒體信息，這就對傳統的路由選擇機制提出了新的挑戰。分享友人
