摘要： 弹性是物质的一个主要性质,不论在科学技术研究方面,还是在材料应用方面都要知道材料的弹性,因而弹性的测量是物质的基本参数测量之一。

Abstract: To make total elastic parameter measurements of crystals is very difficult due to the fact that the size of crystals is small, especially for new materials. We improved the Brillouin scattering technique, and using a small crystal as a spherical sample, measured the sound velocity and anistropy. The fitting programs are made to deduce the total elastic parameters from Brillouin measurements. The possible problems in fitting and ways of solving the problems are discussed.
