  1. The basic characteristics of the current data network are point - to - point, connectless, doing one ' s endeavor, no quality of service, etc. these characteristics do not meet the requirement of real - time services, therefore, the realization of voip need support of the some key technology. these technologies includes : speech sound coding and data compression, real - time transmission and control, mute compression and multicast, acoustic - echo cancellation and comfort noise generator, dynamic monitor and guarantee of quality of network service, as well as, the compatible of different network and different protocol with each other

    但現有的數據網路的基本特性：點對點的、無連接的、盡力而為的、沒有服務質量保證等特性並不適合與實時的業務要求，因此voip的實現需要一些關鍵技術的支持，這些技術包括：語音編碼和壓縮技術、實時傳輸和控制技術、組播技術、靜音壓縮和舒適噪聲生成技術、回聲消除技術、網路服務質量的動態監測和保證技術、以及不同的網路、不同的協議之間的互連互通等等。
  2. Abn airborne noise

  3. For recent years, adsl has world widely employed and widely used in many aspects such as vod, remote medical treatment and e - shopping etc. but we noticed that the traditional telephone networks are designed for the transmission of low frequency signals, and the adsl ' s frequency rang is from 0 to 1. 104mhz, so we must confront the signal attenuation, the loop line noise impairments, the crosstalk interferences, the bridge tap reflections and the rf disturbances problems and many other problems when transmitting the adsl signals one the telephone networks

    近幾年來， adsl在世界范圍內得到充分的使用，廣泛應用於視頻點播、遠程醫療、網上購物等各個方面。但是由於電話線網路是專門為傳輸低頻信號而設計，而adsl的頻譜范圍在0 1 . 104mhz內，因此在傳輸adsl信號時，面臨著信號衰減、線路噪聲、串音干擾、橋接抽頭反射和射頻干擾等等多方面的問題，這就要求在adsl開通之前對線路進行一系列的測試。
  4. At the same time this paper calculates the effect of train velocity on noise propagation, when mach number is 0. 1, sound velocity less effects on noise level ; when mach number is 0. 4, the difference value is about 2db whether to consider the sound velocity. so when the train velocity is not very high, the effect of sound velocity may not be considered

    本文同時計算了列車運行速度對噪聲傳播的影響，當馬赫數為0 . 1時，聲音的傳播速度對聲級的影響是很小的，當馬赫數為0 . 4時，考慮聲速與不考慮聲速影響的最大值的差值大約為2db左右，因此在列車速度不是很高的情況下可以不考慮聲速的影響。
  5. The fonnation of the effect of ideological - political education communication is formed in the communicating process of it, so the research to this process requires a construction mode. in the long run practice, especially in the condition of meditate economy, our ideological - political work had followed the mode of oneway imbue, which has some malpractices. firstly, it took the communicating process as a single process and ignored the feedback factors ; secondly, it did not take the complex and changeable factors into consideration ; thirdly, it lacked the systematic analyze of the connection among all factors, moreover, it did not realize the " noise " affluence during the communicating process

    在長期的實踐中，尤其是在計劃經濟體制下，我國的思想政治教育傳播工作形成了單向灌輸型的傳播過程模式，這一模式存在明顯的弊端：一是把傳播過程看成是單向的過程，忽視了反饋因素；二是把傳播看成單一條件下的傳播，沒有考慮復雜的、多變的環境因素；三是缺少對各要素間關系的系統分析，而且沒有認識到信息正傳播的過程中會受到噪音的影響。
  6. All this can resolve the problem of noise. to have better effects of denoise, this article propose that the core of denoise is to control the noise driving source adding to develop transmission path of noise

    本文提出以控制噪音激勵源為核心、控制噪音傳播途徑的綜合措施來實現電控門噪音控制的具體方法，是最為簡便和有效的噪音控制方法。
