With the current condition , the paper raises the point of synchronization in the qe1 ' s development , including the synchronization of bit , frame , multiframe and network and analyses the performance frame synchronization system based on the theory of probability and finally explains the realization of the technology of synchronization . the hardware circuit diagram of qe1 and some software flow chart have been offered in the paper 在针对qe1中继板卡系统实际的开发情况后，本文分析了该系统所涉及的同步问题(包括位同步、帧同步、复帧同步和网同步) ，在概率论的基础上分析了qe1系统的帧同步系统的性能，并研究了各种同步技术在qe1中的实现。
