摘要：
The elastic properties of the vitreous system Bi2O3-B2O3 have been measured by ultrasonic pulse echo overlap technique at a frequency of 10 MHz and at room temperature. For the purpose of measuring the ultrasonic velocity with high accuracy, the McSkimin criterion for determining the correct cyclic overlap between echoes is used. The elastic properties of the present glass system as a function of composition are discussed on the basis of the elastic internal energy due to the deformation. Also presented is a full discussion of the Poisson's ratio; which is found to be rather sensitive to the glass composition.
