 note = {This paper is described on the eigen-value equation and the secular equation for plane elastic waves in single crystals about which the piezoelectric repulsion stress is strictly considered. Also the conditions are shown under which pure plane elastic waves, that is, pure modes in crystals must be satisfied. Applying this theory to the thickness quartz crystal plate, the following main points are shown. 1) All the cutting angles of the crystal plate with pure modes. 2) All the inclined angles of the displacement vector for the wave vector of quasi-modes in the crystal plate. 3) The relation between the purity of modes and its frequency temperature coefficient in the crystal plate., Article, 信州大学工学部紀要 34: 155-166 (1973)},
