这些问题的提出就使得深海海底表层沉积物的保真取样技术研究非常有必要。
So, all above mentioned makes it necessary to study the truth-preserving sampling technique for the deep-sea surface layer sediments.
这些结果与海底浅表层沉积物的物理力学性质、颗粒接触状态、颗粒的微结构等特征有关。
These results are related to the characteristics of seafloor surface sediments such as physical-mechanical features, grain contact state and sediment microstructure, etc.
