1986年，我们纪念了地球内核发现50周年。在原子物理学中，一个同等的行为将会获得诺贝尔奖。这归功于英格·莱曼(图1)，他在1936年作为一名地震学家在哥本哈根的丹麦皇家大地研究所工作。她的建议发表在《国际地震局，特拉沃科学》上[Lehmann，1936]：需要对P3‘波[即PKIKP]作出解释，因为现在很难认为它是由衍射引起的。这里将提出一个假设，它似乎具有一定的概率，尽管它无法从手头的数据中得到证实。我们把它当作…在核的内部有一个内核，它的速度大于外核。
In 1986, we marked the 50th anniversary of the discovery of the earth's innercore. In atomic physics an equivalent act would warrant a Nobel prize. The credit is due to Inge Lehmann (Figure 1), who in 1936 was working as a seismologist at the Royal Danish Geodetic Institute, Copenhagen. Her proposal was published in the Bureau Central Seismologique International, Travaux Scientifique [Lehmann, 1936]:An explanation of the P3′ wave [i.e., PKIKP] is required, since now it can hardly be considered probable that it is due to diffraction. A hypothesis will be here suggested which seems to hold some probability, although it cannot be proved from the data at hand. We take it… that inside the core there is an inner core in which the velocity is larger than the outer core.
