lower mantle

基本解释

Like the core of earth, the mantle can also be divided into two concentric layers, the lower mantle and the upper mantle.
就像地球的核部一样。地幔也可分为两个同心圆圈层，下地幔和上地幔。
PREMA(FOZO) is a popular end member of mantle for all ocean island and flood basalts, probably representing the lower mantle.
PREMA(FOZO)则是洋岛玄武岩和溢流玄武岩公共端员。
These forces change the configurations of electrons in the mineral ferropericlase in the lower mantle, making it "softer" than previously estimated.
这些力量改变了在低地幔中矿石低铁黑硬绿泥石中电子的结构，使其比之前估计的更“软”。
Comparing low degree geoid anomaly with mantle density anomaly, The authors think the earth shape asymmetry is mainly caused by lower mantle density inhomogeneity.
对比分析低阶大地水准面异常和地幔密度异常结果表明，地球形状非对称性主要是由下地幔的物质密度不均匀引起的。
These researches supply the fundamentals phycical constrains on establishing the mineralogical model of the Earth's lower mantle and the chemical composition of core-mantle boundary (CMB).
这一问题的研究将对限定下地幔的矿物学模型和核-幔边界处的物质成份,以及对下地幔和核一幔边界处的地震波速结构的解释提供基础物理依据。
