Technical development of elastic wave velocity measurement on partially molten peridotite at high pressures and high temperatures

部分熔融橄榄岩弹性波速测量技术的发展主要有以下三个方面：(1)在高于前人研究的温度下（高达1400℃）开展弹性波速测量；(2)在被封装的熔融样品中开展弹性波速测量；(3)研究超声波频率对部分熔融橄榄岩弹性波信号的影响。因此，我成功地开发了部分熔融橄榄岩的弹性波速测量，达到5 GPa和1700℃。

Technical development of elastic wave velocity measurement on partially molten peridotite was conducted mainly for following three issues : (1)Development of elastic wave velocity measurement at temperatures higher than previous studies (up to 1400℃), (2) Development of elastic wave velocity measurement for capsulated molten sample, (3) Investigation for the effect of ultrasonic frequency on elastic wave signal from partially molten peridotite. As a result, I succeeded to develop elastic wave velocity measurements on partially molten peridotite up to 5 GPa and 1700℃.
