Numerical test shows that the method presented in this paper can be applied in the lateral inhomogeneity study of the earth interior 数值检验表明，本文所提出的横向非均匀介质接收函数的数值模拟与偏移成像可用于地球内部介质横向不均匀性的研究。
Sir joseph larmor , an irish mathematician , proposed in 1919 that it was generated spontaneously by the swirling of molten metal inside the planet 1919年，爱尔兰的数学家约瑟夫?拉莫尔提出它是随着地球内部已溶金属（导电流体）的旋转而自然形成的。
To recreate the effect of heat flowing through the planet ' s interior , the researchers stirred this brew with iron paddles attached to iron discs placed at each end of the tank 为了能重现地球内部热量运动的效果，研究人员将与容器两端的铁盘相连的铁桨浸于溶液内，并搅拌。
The displacement vectors caused by the tide - generating force are different for different points inside the earth , hence tidal strain and stress fields are formed inside the earth 地球内部各个质点在月亮和太阳的起潮力作用下产生的位移矢量不同，在地球内部形成固体潮应变场和应力场。
This study provides plentiful information for the interpretation of the material property and geodynamic of earth interior of china area , and also help to understand the interior viscidity structure of china area 这为解释中国大陆区域地球内部介质性质和探讨地球动力学提供丰富的信息。
Two of the most predominant characteristics of surface wave are dispersion and attenuation which are the effective tools to study the velocity structure and viscidity structure of the earth interior 频敌和衰减是面波传播中的两个基本特征，利用面波频散和衰减可以有效地研究地球内部速度结构和粘弹性结构。
It was the compass , too , which revealed that the earth itself has a magnetic field and thus led to the first serious question about the planet ' s internal structure : what is down there that generates this field 这样也就引起了第一个关于地球内部结构的严肃提问：地球内部到底存在何物致使了磁场效应的产生？
It may sound like the latest fantasy adventure game or a new indiana jones movie , but it happens to be what scientists discovered in 1995 with a sophisticated computer model of earth ' s inner core 它听起来像最近的幻想冒险比赛或新的印地安那州琼斯电影,但是这正好是科学家在1995年以地球内部中心复杂的计算机模型模拟发现的。
There ' s the legend . . . that hitler and many of his nazi minions escaped germany in the closing days of world war ii and fled to antarctica where at the south pole they had discovered an entrance to the earth ' s interior 有个传说. . .西特勒和他的许多亲信在第二次世界大战结束的日子里逃离了德国而逃到南极洲，在南极他们发现一个通向地球内部的入口。
Most of earth ' s internal heat is generated by four long - lived radioisotopes ? potassium 40 , thorium 232 , uranium 235 and uranium 238 ? that release energy over billions of years as they decay into stable isotopes 地球内部的热能主要来自半衰期较长的四种放射性同位素钾40 、钍232 、铀235与铀238 ，它们在几十亿年来逐渐衰变成稳定的同位素，同时释放能量。
