超高压技术的发展,为人类认识自然打开了一扇新的窗户。它有力地推动了物理学、天文学、地学和材料科学的研究工作,并有可能揭示出周围物质世界中的一些奥秘和发现一些更新的现象。 地球物理和地球化学工作者长期以来很希望获得关于地球深部的资料。但这些资料很少,主要是根据地震和对假定存在于地球深部的某些矿物的电导及其它性质的测量而作出的推论。过去在实验室里建立下地幔的温度和压力条件(尤其是压力要达到300—1500千巴)有相当大的困难,即使用冲击波技术也只能在瞬间建立这种条件。因此大大地限制了人们对地球深部物质的状态和性质的认识。金刚石窗口压腔这一新技术的出现,为地球深部的研究工作打开了新的局面。
The development of EHV technology opens up a new window for human understanding. It has strongly promoted research in physics, astronomy, geosciences and materials science, and has the potential to reveal some of the mysteries in the surrounding material world and to discover some newer phenomena. Geophysical and geochemical workers have long been interested in obtaining information about deep earth. However, these data are rare and are mainly based on inferences from earthquakes and measurements of the conductance and other properties of certain minerals that are presumed to exist deep in the Earth. In the past there have been considerable difficulties in establishing the temperature and pressure conditions of the lower mantle in the laboratory (especially at pressures of 300-1500 kPa), which can only be established instantaneously using shockwave techniques. Thus greatly limiting people’s awareness of the state and nature of the Earth’s deep matter. The emergence of this new technology of diamond window pressure chamber opened up a new situation for the research on the deep earth.
