downward continuation meaning in Chinese
向下延拓
Examples
- The mathematics required for more sophisticated treatment of downward continuation is beyond the level of this book .
对于向下延拓更完善的论述所需要的数学已越出本书的范围。 - Discrete approach with 15 ' 15 ' grid is adopted in order to numerically simulate and calculate the gravitational potential field generated by the homogeneous rotation - symmetric ellipsoid , and it is verified that the method , the fictitious compress - recovery and the fictitious downward continuation of the gravitational field , is reliable and valuable at the relative accuracy level higher than 10 ^ ( - 4 )
摘要采用15 ' 15 '网格离散化手段对均质旋转对称椭球体产生的引力位场进行了数值模拟计算，在相对精度优于10 ^ ( - 4 )的水平上，验证了引力位虚拟压缩恢复法以及重力场虚拟向下延拓法的可靠性和有效性。 - For solving the problems that downward continuation of the space gravity anomaly can not be used in downward continuation of sea surface gravity anomaly , on the basis of prey principle used to compute gravity in the surface - layer of the earth , and with considering the density of sea water and sea bottom topography , two new methods are proposed
摘要针对空间重力异常向下延拓方法不适用于海面重力异常向下延拓的问题，根据珀雷原理求地球表层内部重力的方法、海水密度及海底地形的特征，提出了两种海面重力异常向下延拓的算法。
