摘要
A new approach to determine all the electro-elastic constants of the piezoelectric crystals in class 4mm has been put forward. As an example, all the constants of Lithium Tetraborate (Li2B4O7) crystal have been measured by means of the approach.The outstanding advantage of the approach is that it only needs to employ in measurement three crystal plates differently oriented.
