摘　　要：本设计为一种压电材料复参数自动测量系统,提出了该测量系统所用的一种快速、精确的自动测量算法—自动迭代算法。其优点是:与常用的Smits迭代法相比,参数初值的选取是与Smits迭代精度接近的Sherrit算法的终值,更加接近真值以减少迭代次数,加快算法速度;频率点的选取遵循一定的规则,以保证迭代的收敛性和测量的自动运行。The paper designed a piezoelectric material complex parameter automatic measuring system, and gave a fast, precise automatic measuring algorithm that themeasuring system used. The algorithm＇ s merit was that selection of the first para-meter value further approached real value. It not only reduced iterative frequency, but also accelerated algorithm speed. Frequency spots＇s selection followed fixed rule and ensured iterative constriction and measurement＇s automatic operation.
