对东太平洋 Ｃ Ｃ 区内 １ 万多公里的浅地层剖面探测资料进行了统计分析， 并对深海浅地层剖面特征及其与多金属结核丰度的关系作了研究， 结果表明： 多金属结核的富集度与海底声反射率呈正比关系， 影响和控制结核丰度的主要因素是海底地形。一般透明层愈厚， 结核愈富集， 但不是对应关系； 层状层或散射层发育， 则多金属结核富集， 反之则不富集
Based on the statistical analysis of the shallow formation profile data of over 10,000 km in the C C area of the eastern Pacific Ocean and the relationship between the profile characteristics of the deep layer shallow sea layer and the abundance of polymetallic nodules, the results show that: There is a direct relationship between the enrichment degree and the acoustic reflectivity of the seafloor. The main factor affecting and controlling the abundance of tuberculosis is the seafloor topography. The thicker the transparent layer generally, the more concentrated the tuberculosis, but not the corresponding relationship; layer or scattering layer development, the enrichment of polymetallic nodules, and vice versa is not enriched
