So we need consider the effects of the earth curvature. In global integration, the requirement of the data coverage and the computation are comparative high. In this thesis, a moving coordinate system is used to overcome the effects of the earth curvature. And a differential calculation concept is proposed that assumes the difference of geoid calculated between the central point and its marginal point is constant when the integration area is far away from the central point.

论文中提出了利用柱体积分时采用移动坐标系来顾及地球弯曲的影响，并利用差分的概念，设想离计算区域到一定距离后，流动点对计算区域内的中心点和边缘点的影响之差为一常数，并用试验的方法，统计分析了它们对大地水准面的有效积分拓展范围。

Combining a new geoid model (EIGEN-GL04S) recovered from GRACE mission and the KMSS04 model, a new mean dynamic ocean topography model are estimated over the Antarctic region. The surface Antarctic Circumpolar Current field and its Polar Front and sub-Antarctic Front are derived from MDT after filtering with a wavelet denoising method.

For cartographical purposes heights are necessarily recorded above the geoid.

就制图的目的来说，所以需记录的高程是高出大地水准面的高程。

The performance of retracking is assessed by comparing SSH with geoidal heights from a high resolution geoid model around Taiwan.

重定之成果是藉由大地起伏比较海水面高来评估，该大地起伏是由台湾周围高解析度大地水准面模型而得。

Based on the summary of newest progresses of global gravity field models, isostatic models and flexural theory of Hthosphere and making used of global gravity model (UTCSR GRACE/GFZ EIGEN-GRACE), First, I calculate geoidal anomalies with different degrees and orders, isostatic residual geoidal anomalies of Hthosphere and horizontal stress distribution in Chinese mainland and vicinity and make an interpretation with multi-levels isostatic equilibrium. Secondly, combination with surface geology and others geophysical data, I analyze detailed structure of lithosphere within various segments of the central orogenic system, respectively. Then, On the basis of making a comparative analysis with among East-Asian tomography, anomalies of geoid and satellite magnetic field for lithosphere and gravity and aeromagnetic, I propose a the lithospheric structural framework model for the Chinese mainland and adjacent area, specially the COS.
