| 1. | Vast quantities of soil reach the gulf of mexico to become ocean sediment .
有大量的泥沙到达墨西哥湾，变成了海洋沉积物。 |
| 2. | Determination of rare - earth elements in ocean sediments by icp - aes
等离子体发射光谱法直接测定海洋沉积物中的微量稀土元素 |
| 3. | Since time immemorial , methane and oil have seeped from beds buried beneath the ocean sediment off the california coast
自从远古时代开始，甲烷和石油便开始从海底向外渗出。 |
| 4. | The pb isotopic ratios show the characteristic of dupal anomaly and influence of ocean sediment to the source
Pb同位素研究也显示了dupal异常型的特征以及大洋沉积物对源区的影响。 |
| 5. | Because of their prominent advantages compared with other achieves of environmental change , the study of high - resolution sequence of environmental change during the late quaternary mainly depends on the polar ice - core and deep ocean sediment
由于冰芯与深海沉积和其它环境演化信息的记录载体相比优势明显，国际上的晚第四纪高分辨率环境演化序列研究多采用冰芯与深海沉积序列。 |
| 6. | In the recent years numerous scientists have found that there appeared many abrupt climatic changes during the last glacial by studying the high - resolution achieves of environmental change such as polar ice - core , deep ocean sediment and loess - palaeosol sequence et al
近十几年来，随着研究技术和方法手段的进步，许多科学家通过对极地冰芯、深海沉积物、黄土-古土壤等环境演化信息载体的研究，在末次冰期中发现了许多气候突变事件。 |
| 7. | The results improve our understanding of the utility of tl as an indicator of sedimentary environment and provide insight into what types of ocean sediments are amenable for study . the comparison of the 18o with the tl cycles indicates that the tl dose display the expected coupling relation with interglacial and glacial climate cycles
尤以位于东经90海岭上的以远洋沉积作用为主的md81349岩芯最为理想，陆源剥蚀产物在其沉积记录中所占比例较少，有孔虫和超微化石为代表的远洋成因的灰白色生物软泥构成主要的沉积组分。 |
