摘要：
Manganin stress gauges have been used to determine the Hugoniots of two ferroelectric ceramics, lead zirconium titanate (PZT) and a similar material modified with tin (PSZT). Comparison with previously published data shows close agreement between our results for PZT and earlier work. The Hugoniot Elastic Limit has been determined, and also agrees with previous data. In the case of PSZT, the Hugoniot in terms of stress and particle velocity is similar to PZT. In terms of elastic wave velocity - particle velocity, results show an overall increase, in contrast to PZT, where wave speed was observed to decrease with increasing particle velocity.
