Abstract：An orthogonal plate is an orthorhombic aggregate of tiny crystallines. The orientation distribution of crystals in the polycrystal (described by the texture coefficients in the orientation distribution function ODF) affects the propagation velocity of Rayleigh wave. Introduced the texture coefficient of polycrystalline into material elastic tensor, through the characteristic value method and the linearization processing, get the relation between the texture coefficient of cubic crystallite orthorhombic with Rayleigh wave velocity. On this basis, through the measurement of Rayleigh wave velocity to get the texture coefficient, and compared with the texture coefficient which measured by ultrasonic transverse wave and longitudinal wave velocity. The results measured by two methods are similar.
