摘　　要：本文描述了一个基于LabVIEW的虚拟仪器系统。该系统能采集、记录和处理人体多处典型部位的脉搏波,用改进的高斯函数(钟形波)叠加模型,通过非线性拟合算法――Levenberg-Marquardt(LM)算法提取脉图特征。实验表明:该模型和算法能简单有效地对各类脉图进行特征识别,识别率达到90%以上。This paper describes a virtual instrument system based on LabVIEW. This system can sample, record and handle various pulse waves which are obtained from different body point, and also, use an improved Gauss function combination model to acquire the characteristic of pulse wave by nonlinear curve fitting -- Levenberg-Marquardt （LM）arithmetic. Experiments show that it is an effective and simple way to identify the characteristic of pulse wave by using this arithmetic model, the identification ratio can reach to 90%.
