Pressure-shear waves were produced in Y-cut α quartz crystals by normal impact with their linearly elastic anisotropism. This provided a way to research the response of materials under pressure-shear loading, experimentally. Because of the piezoelectricity of quartz, VISAR technique was used in the experemental measureinent abroad. In our work,Manganin piezoresistive method and electric-magnetic partical velocity method were first adoptes for getting the internal state variation of samples. In our experiment the surfaces of quartz pieces were electroplated with silver lays of 1μm thick by means of magnetic-controlled shoot, which neutralized polarized current and covered polarized electric field. Lonsequently the piezoelectric interference was eliminated.
