摘要

在实验数据的基础上，采用三维慢面法对BaTeMo2O9单晶的纯模轴进行了研究。研究了慢速面与纯模态轴的关系。在考虑压电效应的情况下，计算了压电加筋弹性常数。利用软件程序确定了BaTeMo2O9晶体的纯模轴，并在慢速表面上进行了绘制。结果表明，Y轴和Z轴是单晶BaTeMo2O9的纯模轴。理论计算证明了计算结果的有效性。

Pure mode axes of single crystal BaTeMo2O9

The three-dimensional slowness surface method is used to investigate the pure mode axes of single crystal BaTeMo2O9 on the basis of the experimental data. The relationship of the slowness surface and pure mode axes is studied. Under the condition of taking account of the piezoelectric effect, the piezoelectrically stiffened elastic constants are calculated. Pure mode axes of the BaTeMo2O9 crystal are determined and plotted out on the slowness surfaces by software program. The result indicates that Y axis and Z axis are the pure mode axes of single crystal BaTeMo2O9. The validity of the result has been proved by theoretical calculation.
