考虑了以轮廓模式振动的方板对确定压电系数的适用性。这种板上的压电测量为各种模式的理论解提供了检验，特别是为位移的分布提供了检验。最近出版的方板的解构成了这项工作的基础，并讨论了这些解的可靠性。所用材料为氯酸钠、溴酸钠、石英、磷酸二氢铵和酒石酸乙二胺(EDT)。对这些材料的弹性系数和压电系数进行了新的测定，但EDT除外，其数据已在以前的一篇论文中发表
The suitability of square plates, vibrating in contour modes, for the determination of piezoelectric coefficients is considered. Piezoelectric measurements on such plates provide checks for the theoretical solution of the various modes and in particular for the distribution of displacement. The recently published solutions for square plates form a basis for this work and the reliability of these solutions is discussed. The materials used were sodium chlorate, sodium bromate, quartz, ammonium dihydrogen phosphate and ethylene diamine tartrate (EDT). New determinations of the elastic and piezoelectric coefficients of these materials have been made, with the exception of EDT, the data for which were published in a previous paper
