导纳谱方法(阻抗谱方法)是电化学测试技术中一类十分重要的方法，现有的商用仪器无法实现快速动态测试，且价格昂贵，体积庞大。文中提出将虚拟仪器技术应用于导纳谱仪的研制，实现了导纳谱仪的动态化。文中通过选择合适的模型，可以直接求得电容参数；通过与传统的电化学工作站进行测试数据的比较，验证了该仪器的准确性；最后对蔗糖溶解的动态过程进行了动态测试，并对实验结果进行了分析。文中首次通过“微元法”原理实现了导纳谱的动态化测试，不仅对目前电化学仪器的动态化设计开发，而且对动态进行的化学和生物等变化过程都具有较大的理论和实际意义。

Admittance spectroscopy method ( impedance spectroscopy electrochemical testing technology) is a kind of important method in electrochemical testing technology. The existing equipment cannot achieve fast dynamic test,and they are also expensive and huge. Pro-pose the application of virtual instrument in the development of admittance spectroscopy instrument,so the instrument can realize dynamic testing. In this paper,by choosing the appropriate model,can directly obtain the capacitance of the system. And the instrument is proved to be reliable compared with conventional electrochemical workstation. Finally,analyze the dynamic process of sucrose dissolving. Firstly re-alize the dynamic testing by “differential method”,it is of great theoretical and practical significance on the design and development of dynamic electrochemical instrument and the dynamic chemical and biological process.
