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的问题：(1)高于以往研究(高达1400℃)的弹性波速测量技术的发展；(2)包裹式熔融样品弹性波速测量技术的发展；(3)超声波频率对部分熔融橄榄岩弹性波信号影响的研究。因此，我成功地在部分熔融的橄榄岩上进行了高达5 Gpa和1700℃的弹性波速测量。

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℃.
