英文摘要 | The variation of complex compliance with temperature (20-50℃) and frequency (0.5-18MHz) were calculated from the ultrasonic velocity and absorption. The imaginal part of the complex compliance is very small compared with the real part. The variation of the real part of the complex compliance with temperature and frequency had the same tendency with the variation of valocity and absorption, and these variation had no influence in high frequency. But the imaginal part, it can be seen that it had a minimum while the frequency is about 2.0 MHz. |
