摘要：
Ultrasonic velocity and attenuation in copper-tellurite glasses of different compositions were measured in the temperature range 80-300 K. For the samples with CuO content less than 20 mol% a remarkable change in the behaviour of ultrasonic properties is observed with temperature. However, for the sample having more than 20 mol% of CuO no such changes occur. These changes in behaviour are attributed to the structural,change in coordination polyhedron which are induced as the controllable parameters, namely, temperature and composition are varied.
