  2. Bits supplies the synchronous timing signal to these equipments inside the telecommunicationt building, such as dps, atm, no. 7, dxc, tm & adm in sdh, don and in etc. the related techniques are involved in the content of synchronization ne twork, timing distribution, the timing signal transportations x impairments etc. the second chapter tells the structure and the function of the building integrated timing system. the third chapter summarizes the digital synchronization network techniques, which emphasizes the basic concept of synchronization networks analyzes the necessity of building the synchronization network and introduces all kinds of synchronization methods. the fourth chapter represents the transportation of the synchronization signal

    本文第二章講述了通信樓綜合定時系統的構成及作用：第三章概述了數字同步網技術，著重描述了同步網的基本概念，分析了建立同步網的必要性，講述了各種同步方法；第四章闡述了同步定時信號的傳輸；第五章介紹了bits設備所支持的同步狀態消息；第六章、第七章為本文的重點，通過對時鐘信號建立數學模型，從理論上分析時鐘內部噪聲和相位瞬變產生時鐘定時信號損傷的原理，企圖尋找到更好地控制頻率漂移的方法。
  3. The results showed : the stability of 2m holographic platform that of jqs - b holographic platform ; the property of tremble isolation was satisfied because the excursion was under 1 / 8 stripe for the outside disturb, the property of tremble elimination was also satisfied because the stripe couls be rapidly stabilified after the artificial stripe tremble

    結果表明， 2m多功能全息平臺比jqs - b型全息平臺的穩定性好；對于外來的干擾，檢測時產生的條紋漂移量不超過1 / 8條，說明工作臺隔震效果較好；對於人為引入的干擾，條紋急速晃動后能在幾秒鐘穩定下來，則表明平臺消震性能良好。
