| 7. | Multispectral data for bathymetry is often performed in relatively clear shallow waters , up to now , no one use multispectral data for bathymetry in estuary waters of yellow river , where the highest sediment concentration in the world has been observed . in another part of this thesis , multispectral data acquired by landsat - 5 tm and in situ data are used for bathymetry in estuarine waters of yellow river . statistical models based on one band and two bands of tm respectively are developed
利用两期水深的比对可以揭示黄河水下三角洲的冲淤演变规律，但由于实测水深资料获取较为困难，因而利用遥感来反演水深是一个重要的选择，为此，本文在黄河口海现代黄河三角洲冲淤演变规律与遥感应用研究端走取两个试验区进行了多光谱遥感水深反演试验，试验结果表明，在极高泥沙浓度、较强水动力条件的黄河口海域，用多光谱遥感反演水深是可行的。 |

| 10. | Amore 2001 has successfully investigated the gakkel ridge and arctic ocean in vicinity of its geological and geophysical nature , as well as the nature of sea ice and biology in this area . the preliminary onboard petrology and bathymetry results show that the mantle beneath the gakkel ridge with low temperature has only encountered very low degree partial melting during the spreading and there is no any direct relationship between the crust nature and the spreading rate along the gakkel ridge in any simple petrologic way . mantle temperature and fracture zone density also play a major role on the crust nature , besides spreading rate
对所取得资料的初步研究表明gakkel洋中脊之下的地幔仅经受了较低程度的部分熔融，具有较低的温度。 gakkel洋中脊处的地壳性质和岩浆活动与扩张速率之间不存在任何直接的岩石学相关性，扩张而导致的岩石圈顶部的冷却并不是决定洋脊处地壳性质的最重要因素。地幔温度和断裂带的存在与否及其密度对地壳性质具有重要的影响意义。 |
