报告了SrTiO 3在105 K相变附近弹性柔度分量s11的声共振测量结果。所观察到的临界奇异性比早期使用脉冲回波技术的测量所建议的更强，并且比理想晶体临界行为理论所预测的更强。这些结果是一个动态缺陷控制的中心峰现象的指示。
Reports acoustic-resonance measurements of the component s11 of the elastic compliance in SrTiO3 near its 105K phase transition. The observed critical singularity is stronger than that suggested by earlier measurements using pulse-echo techniques, and stronger than that predicted by the theory of ideal crystal critical behaviour. These results are indicative of a dynamic defect-controlled central-peak phenomenon.
