查询词典 mascon

From the view of conservation of organic matter, the water body in evaporates basin takes on the character of density stratification; the niederschlag below mascon has high oxidation-reduction potential, which contribute to the conservation of organic matter. From the view of generation of hydrocarbon, bacteria, algae and lithology on the bottom of salt-water basin play important role in generation of hydrocarbon; furthermore, clunch from the redbeds acting as catalyzer, alkali metals making the hydrocarbon mobile.

从油气生成条件看，细菌、藻类及咸水盆地底层的岩性对油气的生成具有重要作用，此外红层中的粘土对烃类的生成起到催化的作用，碱金属可使生成的烃类发生流动；从有机质的保存条件看，蒸发岩盆地水体中具有密度分层的特点，在高密度层以下的沉积物具有强的氧化还原电位，从而使有机质保存下来。

This paper reviewed main progress in lunar gravity field and topography modeling, and summarized main results of lunar gravity study, especially those related to the lunar crust and mascon structure.

本文回顾了月球重力测量及月球重力场模型、月球地形模型等主要研究进展，总结了月球重力场在月球内部结构研究，特别是在月壳结构以及月球质量瘤等方面取得的研究成果。

According to authors' understanding on the density contrast of the lunar crustal and mantle materials, depths of typical mascons were estimated using various approaches. The estimations indicate that the mascon in Mare Orientale may caused by a lunar mantle plum, a basaltic lava with high density.Key words lunar gravity; mare; Mascon; clementine; lunar prospector

从宏观角度看，月球布格重力异常与月球地形起伏是相关的，统计结果表明它们呈弱负相关，从均衡角度来说，在月球停止大规模内部物质运动之前，月球壳幔可能已基本达到均衡；从Mascon深度估算结果来看，一些大型的Mascon基本属于玄武岩浆&充填&型的，少数Mascon可能与月幔柱有关，如东方海Mascon。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.
