测地线

This thesis aimed at this hotspot, also one of the important regions during the Ninth-and Tenth-Five-Year-Program periods of Chinese Antarctic research. It made use of Radio Echo-Sounding data, surface horizontal ice flow velocity data, digital elevation model data, surface mass accumulation data and the data concerning melting at the bottom of Amery Ice Shelf , to study the grounding line, mass balance, and ice kinematic characteristics of grounded ice sheet and floating ice shelf respectively.

本论文瞄准国际上的这一研究热点地区，同时也是我国"九五"及"十五"期间的南极研究重点地区，利用无线电回波测厚数据、冰面流速数据、数字高程模型数据、冰面物质积累数据及冰架底部融化数据等，对该地区的接地线、物质平衡、陆地冰盖和漂浮冰架的冰川运动学特征等进行了研究。

It is useful for the direct and inverse solution of geodesic problem and applying in digital elevation model and 3D GIS model. geodesic coordinate system ; direction angle ; geodesic line ; differential relationship

本文则进一步探讨测地坐标的一些微分性质和微分关系式。1 基于测地坐标的大地线的二阶微分方程按照曲面的内蕴几何学，由

In order to tr a nsform conveniently the direction a l a ngle of a geodesic line into the geodetic a zimuth,the solution of the meridi a n a l convergence is expressed by geodesic coordin a tes of this point.

该解式直接采用该点的测地坐标来求解子午线收敛角，从而能方便地将测地坐标系中任一大地线的方向角转换为大地方位角。

We don t expect students to be sponges. You can t expect to absorb everything and not have any questions to ask.

我们并不期待我们的学生是一块海绵，你没可能接收所有的东西而不提出任何问题。
