地球深部地震波速度的分析有着悠久的历史，并吸引着越来越多的研究者。几乎在地震波传播时间一得到，威廉姆森和亚当斯（1923）就用它们来获得速度剖面，并检查它们与均匀材料自压缩产生的密度的一致性。伯奇（Birch，1939年）通过将压力的影响纳入他对浅部地球密度和地幔深度波速的外推，解决了同样的均匀性和成分问题。由于地震波（广义上也包括简正波）构成了我们对地球结构的主要探测，这种传统的利用地震学数据来研究地幔性质和现象的做法仍在继续。例如，地核衍射的P波和S波（Wysession & Oka} 1988，1989）携带
The analysis of seismic velocities at depth within the Earth has a long history and attracts an increasingly broad spectrum of researchers. Almost as soon as seismic travel times were available, Williamson & Adams (1923) used them to obtain velocity profiles and check their consistency with the densities that would result from self-compression of a uniform material. Birch (1939) addressed the same question of homogeneity and composition by incorporating the effect of pressure in his extrapolation of the shallow Earth's density and wave speeds to mantle depths. This traditional use of seismological data to investigate mantle properties and phenomena continues since seismic waves (in a broad sense that includes normal modes as well) constitute our primary probe of Earth structure. For example, core-diffracted P and S waves (Wysession & Oka} 1988, 1989) carry
