在二进制位同步通信中，使用时钟脉冲来控制数据和控制字符的同步。
In binary synchronous communication, the use of clock pulses to control synchronization of data and control characters.
如果没有同步脉冲的话，接收机就不能把握住时机来预计下一个数据包的到达时间。
Without a synchronizing pulse, the receiver cannot use timing to predict when the next group will arrive.
该系统主要由分光系统、CCD传感器、光脉冲同步信号发生器、数据采集卡及计算机等部分组成。
The system mainly consists of a beam-splitting system, a linear CCD, a pulse laser synchronous signal generator, a sampling data card and a computer.
