摘　　要：目的:开发PC机与单片机相结合的穴位伏安特性计算机测试系统。方法:PC机与单片机通过串口通讯,给单片机发送控制参数,并将采集到的数据读回,绘出伏安曲线、记录和分析处理相应的数据。单片机系统根据PC机发出的控制参数产生扫描电流加到探头上进行测量,并将电压数据读取发给PC机。结果:用本检测系统对正常人体的穴位进行测量,发现人体穴位伏安曲线呈现明显的非线性特征,均表现为增程曲线上穿减程曲线,形成一个类似磁滞回线的惯性区域。结论:本检测系统可准确、稳定、可靠地检测人体穴位的伏安特性。Objective：It was to develop the detection system of acupoints＇ volt - ampere characteristics by combining both singlechip and PC. Methods ： PC and singlechip were connected through COM port. PC transmited control parameters such as scanning time, start signal, stop signal and etc. to singlechip, sended back the data gathered from singlechip to PC ,and then drew volt - ampere curve, records and analysed related data on PC. On the other hand, according to the control parameters it received, singlechip generated precise scanning electric and currented to the detector head to measure those acupoints and send back voltage data to PC. Result ：The experiment of measuring the acupoints of normal people under the detection system showed that the volt - ampere curves of human acupoints had nonlinear characteristic, for all ascending curves move upward across descending curves, which formed an inertia area. Conclusion：Our detection system can detect human acupoints＇volt - ampere characteristics exactly, stably and reliably.
