摘　　要：介绍了测试系统静态、动态特性参数的分析方法,指出了传统方法的不足。在此基础上,运用图形化编程语言LabVIEW设计了测试系统特性参数分析软件。利用最小二乘拟合、样条插值等数学工具实现了静态特性参数(灵敏度、线性度等)和动态特性参数(固有频率、阻尼比等)的实时计算和分析。实验结果表明:软件具有良好的人机界面、易于操作,计算结果准确、效率较高,完全可以满足工业测试的需要。The analytical method of static and dynamic characteristic parameter of measurement system was introduced. Some faults of the traditional method were indicated. The analytical application of characteristic parameter was designed based on the graphical programming language LabVIEW. Static parameters（sensitivity, linearity, etc） and dynamic parameters（inherence frequency, damp, etc） were carried out on real-time by mathematic method such as least-squares and spline interpolation. The experimental results show that the application has friendly user interface and is operated easily. The result is correct, the efficiency is higher. So it can be competent for industrial measurement.
