| 摘 要： | 通过增加脉搏波采集电路和信号处理电路，扩展短余辉电子示波器的测量功能。脉搏波采集电路采用HK-2000B型脉搏传感器；信号处理包括信号采样、储存和扫描三部分，并通过凌阳SPCE061A型微处理器实现。上述电路使短余辉示波器具有显示和测量脉搏波的功能，该功能丰富了医学物理学中“电子示波器的使用”的实验内容，提高了医学专业学生对物理学实验的兴趣。

| Abstract: | The measuring function of short persistence oscillograph can be extended by adding pulse wave collecting circuit and signal processing circuit.Pulse sensor of HK-2000B was applied as a pulse wave collector.Signal processing function,which was composed of signal sampling,memorizing and scanning,was implemented by Microprocessor of SPCE061A.Those circuits can add function of pulse wave measurement and display to short persistence oscillograph.So the medical physics experiment, application of oscillograph,can be developed.Also,medical students would take more interests in physics experiments. |
