摘　　要：目的:介绍为物理教研室研制的计算机多导生理参数记录仪设计的波形曲线测量程序。方法: 硬件系统由传感器、A/D转换器和486微机组成,软件系统由设计的相应的程序对波形的特征参数进行测量、存贮与打印输出。结果:该系统能测出1-4根曲线的平均幅值、平均周期(频率),存贮一个周期中10点以上感兴趣点的值并具有误测修改功能。结论:本系统采用光标移动法测量,使用简便,操作容易,以微机代替通常采用的四导生理记录仪进行测量,无论从准确性还是使用方面都有很大的好处。Objective： To introduce the design of a computer program of measuring the parameters of recorded wave curve for the Computerized Physiological Parameter Recorder designed By the Department of Physics. Methods： Hardware system was made up of detector, A/D converter and a ,186 computer. Software system was designed by homologous program that could measure, store and print out the characteristic parameters of the wave curve. Results： This system could measure one-four curve average amplitude, average cycle, storage the value of the interested point over ten points in a cycle and had function of revising error. Conclusion： This system adopts cursor motion s way to measure, uses simply, manipulates easily and measures data with microcomputer to substitate the use four leads physiological recorder, Whether the correctness or usage has great advantages. Not only certitude but also use have a great percentage.
