由布里渊散射实验可以得到晶体弹性及压电系数。本文介绍了最优化方法在拟合正交晶体弹性及压电系数中的应用 ,并对几种主要的最优化算法的稳定性、初值选取、拟合数据结果的判断及评价等关键问题做了详细的讨论
The crystal elasticity and piezoelectric coefficient can be obtained from the Brillouin scattering experiment. In this paper, the application of the optimization method in the fitting of orthorhombic elastic and piezoelectric coefficients is introduced. The key problems of the stability, initial value selection, judgment and evaluation of the fitting data results of several main optimization algorithms A detailed discussion
