摘　　要：以非平稳、非线性的轮扫掠力信号为例,围绕其采集及处理来进行陈述,重点研究了利用VC6.0与MATLAB7.0混合编程方法中的动态链接库技术对信号进行经验模式分解(EMD)。程序结合了VC与MATLAB的优点,使得数据采集与处理可在同一VC工程文件中完成,执行速度快,运行稳定且数据处理准确、方便。The acquisition and processing of non-stationary nonlinear wheel-scan force signal, and how to process signal by the method of Empirical Mode Decomposition （EMD） were studied in this paper. The dynamic-link library method of Mixed-Language Programming for VC 6.0 and MATLAB7.0 was used in the procedure, which combines the advantages of VC with MATLAB, ensures the data acquisition and processing finished in the same VC project, makes the signal processing run faster, stable, accurate and convenient.
