摘　　要：介绍了一种微机化极性相关仪的硬件和软件设计考虑,以满足相关法在线测量流速之需要。系统中使用两个微处理机协同工作,因此可以在实时测量的同时进行人机对话和图形显示。仪器具有自相关、互相关、测量时延和速度等多种功能。For satisfying the requirement of on-line flow velocity measurement with correlation me thod, the design consideration of the hardware and software for a microcomputer based polarity correlator is introduced. Two microprocessors cooperate in this system. therefore real-time measruement and man-machine communication and graphic display can be implemented simultaneously. Multifunctions, such as auto correlation, cross correlation, time delay and ve locitv measurements are involved.
