| 摘 要： | 将压电材料参数作为复数考虑，对分析压电材料性能有着实际意义。该文从曲线拟合的思想出发，运用非线性最小二乘法(高斯-牛顿法)来估计压电材料复参数，仿真结果显示，估计值与真实值比较接近，算法的收敛性较强，是压电参数测量的一个实用方法。

| Abstract: | The consideration of the parameters of piezoelectric materials as complex is significant at analysing the performance of piezomaterials. Based on the idea of curve fitting, the nonlinear least squares method (Gauss-Newton method) has been applied to estimate the complex parameters. The emulation results show that the estimated value is close to the real value ,the astringency of algorithm is strong. So as one way of piezoelectric parameter measurement, it is feasible. |
